Top 8 Nature Moments of 2008

This meme seems to be making the rounds again (see here, here, also here), so here are my top nature moments of 2008.

1. Working with raptors in Cape May – not really a "moment" but still the top nature-related experience of the past year.
2. Seeing a Golden Eagle for the first time (up really close).
   
3. Seeing a Scott's Oriole in Union Square – my 300th life bird!
4. Watching a flock of redpolls.
5. Participating in the 10th C&O Canal Count.
6. Waiting for Short-eared Owls in Franklin Twp.
7. Watching Peregrines slicing through wind and rain.
8. Participating in the Lower Hudson and Raritan Estuary CBCs.
   

It is not really a "nature moment," but this event got the year off to a good start.

The State of the Chesapeake

Over the weekend, the Washington Post published a series of articles on the poor health of the Chesapeake Bay and its tributaries. Cleaning up the bay, which has been in serious trouble since the early 1980s is especially complicated since its tributaries pass through multiple jurisdictions; New York, Pennsylvania, Maryland, Delaware, the District of Columbia, Virginia, and West Virginia all contain part of the watershed, which is fed by two major rivers (the Potomac and Susquehanna) and numerous smaller tributaries. That means that cleanup strategies have to be coordinated among the various stakeholders, which then have to fight their own internal battles over funding and enforcement priorities.

In the meantime, work is being left undone.

Maryland, Virginia and Pennsylvania all pledged that their farmers would put up fences along streambanks to keep cows out. But they didn't make it a legal requirement: Officials feared this kind of regulation would be a burden on farmers and would be difficult to enforce....

But in Virginia, many farmers simply didn't want the hassle. And reimbursement funding, which came out of state budget surpluses, was often short. From July 2006 to June 2007, Virginia turned away 144 farmers who wanted to fence off 84 miles of streambank.

Now, Virginia has reached only about 20 percent of its goal for fencing off streams. Across the Chesapeake watershed, the figure is 27 percent.

The problem with cow manure is that it contains nitrogen that feeds algae blooms, which in turn cause dead zones throughout much of the bay. Cow manure is just one of many nitrogen or phosphorus sources within the watershed. Sources include fertilizers, sewage, detergents, and septic tanks, among others. While the cleanup has effected some reductions in nitrogen and phosphorus, and stabilized some underwater life, it has fallen far short of its goals.

Raritan Estuary CBC 2008

Yesterday my mother, sister, and I participated in the 2008 Raritan Estuary Christmas Bird Count. As we have for the past several years (see previous accounts from 2005, 2006, and 2007), we covered a section along the Raritan River in Highland Park and Piscataway. One additional birder joined us this year, so we were able to split into two equal parties to cover our territory more thoroughly.

Despite our best efforts, the numbers of many species seemed down this year. Whether it was the balmy temperatures, the general gloominess of the day, or some other combination of factors, birds were not active or vocalizing in the morning. We had record lows among Song Sparrows, White-throated Sparrows, and Dark-eyed Juncos. Songbirds generally seemed scarcer than usual in both numbers and species.

All was not gloom, however. We had two new species for our section: Green-winged Teal, found by my sister in a Johnson Park pond, and Brown-headed Cowbird. Raptors included a Peregrine Falcon and eight Red-tailed Hawks. One of the latter, a local nester, was almost all white, matching what Brian Wheeler describes as "incomplete albinism." We flushed another (normal) Red-tailed Hawk, which flew off clutching a squirrel. Aside from that, the many flocks of geese, gulls, and starlings kept us busy counting.

We ended the count day by watching an adult Bald Eagle harass gulls in Donaldson Park.

More on the Tennessee Coal Ash Disaster

The flood of water and coal ash from a TVA plant is much larger than the original reports announced – over 1 billion gallons of sludge.

Officials at the authority initially said that about 1.7 million cubic yards of wet coal ash had spilled when the earthen retaining wall of an ash pond at the Kingston Fossil Plant, about 40 miles west of Knoxville, gave way on Monday. But on Thursday they released the results of an aerial survey that showed the actual amount was 5.4 million cubic yards, or enough to flood more than 3,000 acres one foot deep.

The amount now said to have been spilled is larger than the amount the authority initially said was in the pond, 2.6 million cubic yards.

This material is highly toxic. So far TVA officials have announced positive tests for lead and thallium, at levels that cause health problems for humans. The water also contains high levels of iron and manganese, which apparently affects taste but not safety. In addition, federal studies have reported high levels of heavy metals and carcinogens in some coal ash, but so far it is not clear if that is true of the ash at the spill site.

General environmental news

• A dam burst in Kingston, Tennessee, released 300 million gallons of toxic coal ash into nearby towns and the Clinch River and Tennessee River watersheds. The ash had been dumped within the dike by a TVA power plant. State and federal officials so far are playing down the potential hazards, but past government studies have shown that coal ash contains sufficient amounts of carcinogens to pose a health risk.
• Striped bass living in the San Francisco Bay estuary are exposed to multiple toxins prior to birth, with many birth defects (e.g., smaller brains, dysfunctional livers) as a result.
• The FDA is re-opening its investigation of bisphenol-A, a chemical found in many plastic food containers (including baby bottles) made from polycarbonate (plastic #7).
• Meanwhile, the National Resource Council recommended that the EPA investigate the cumulative risk from long-term exposure to phthalates and chemicals that could cause similar problems.
  
• Those decisions come none too soon, since explosure to endocrine disruptors like bisphenol-A has been linked to a variety of birth defects in all major classes of vertebrates. (via)
  

Review: A Guide to the Birds of East Africa

Nicholas Drayson's A Guide to the Birds of East Africa is not actually a field guide (such as this one), but a novel. This book is set in Kenya, a country blessed with one of the most diverse bird populations in the world. (Its principal competitors for that title are in northern South America.) The rich bird diversity makes it a natural setting for the birding competition that comprises most of the narrative.

The premise is as follows. Two old acquaintances (but not exactly friends) find out that they both want to invite the same woman, Rose Mbikwa, to one of Nairobi's premier social events. One, Mr. Malik, has lived in Nairobi for years. The other, Harry Khan, has roots in Kenya but lived most of his life abroad. The two, with the instigation of members of Malik's social club, decide that the proper thing to do is to compete for the right to ask first; whoever sees the most species of birds in one week wins. While the premise has obvious problems, the subsequent plot is executed fairly well with some unexpected twists and turns, and the ending resolves some of the tensions satisfactorily.

So what to make of that title? The author states in an interview that he borrowed the title based on an actual field guide written by a friend. As one might expect in a tale of competitive birding, a great many bird species are mentioned, and in some cases elements of their natural history are discussed. The title makes sense on that level, but I suspect one other meaning. One of the central characters, Rose Mbikwa, is literally "a guide to the birds of East Africa," as she leads weekly bird walks and trains young tour guides to serve the booming ecotourism industry.

There is a good deal of commentary in this Guide regarding Kenya's political and social climate. Rose Mbikwa is the widow of a former government official, and Malik writes pseudonymous political fables for a popular newspaper. Unfortunately I am not in a position to evaluate this commentary since I know little of the Kenyan context. It would be interesting to hear from someone who does know whether Drayson's portrayal is accurate.

A Guide to the Birds of East Africa is a fast and exciting read. It held my attention sufficiently to distract somewhat from my virus-induced misery for a few hours over the weekend. This book is definitely worth a look for anyone who is interested in birding-related fiction.

Penguin Listing

The U.S. Fish and Wildlife Service has proposed listing seven penguin species as either threatened or endangered under the Endangered Species Act. Contemporary penguins face a variety of threats, from climate change altering their habitat to prey declines from overfishing to mortality from longline fishing and predation. Oil spills have also harmed some penguin populations.

Here are the proposed listings.

Endangered

• African Penguin (Spheniscus demersus)

Threatened

• Yellow-eyed Penguin (Megadyptes antipodes)
• White-flippered Penguin (Eudyptula minor albosignata)
• Fiordland Crested Penguin (Eudyptes pachyrhynchus)
• Erect-crested Penguin (Eudyptes sclateri)
• Humboldt Penguin (Spheniscus humboldti)

Threatened in part of its range

• Southern Rockhopper Penguin (Eudyptes chrysocome)

Considered but not listed

• Emperor Penguin (Aptenodytes forsteri)
• Northern Rockhopper Penguin (Eudyptes moseleyi)
• Macaroni Penguin (Eudyptes chrysolophus)

If you would like to comment on the proposal, you can visit www.regulations.gov and search for "penguin." There are three separate dockets for this proposal.

Listing penguins is relatively controversy-free for the government. Since penguins do not occur naturally within the boundaries of the United States, the decision will not impinge significantly on American business or landowner interests. Instead, the main effects of the listing would be that importing or exporting penguin specimens would be illegal without a permit and that Bush's Interior Department would get to increase its paltry list of newly-protected species by a few more birds. While I am pleased to see the Interior Department moving ahead with species protection, I would much prefer to see that movement among those candidate species where U.S. governmental action could do the most good.

Goose Eggs on the Menu for Polar Bears

Snow Goose on Nest / Photo by Matthew Perry (USFWS)

Polar bears may switch to eating snow goose eggs in early spring if accelerated melting pushes them off the pack ice before other prey is available.

"Over 40 years, six subadult male bears were seen among snow goose nests, and four of them were sighted after the year 2000," says Robert Rockwell, a research associate in Ornithology at the American Museum of Natural History and a Professor of Biology at City College at City University of New York. "I've seen a subadult male eat eider duck eggs whole or press its nose against the shell, break it, and eat the contents. This is similar to a different research group's observations of polar bears eating Barnacle Goose eggs on Svalbard, an island near Norway."

Polar bears, Ursus maritimus, are listed as a threatened species under the United States' Endangered Species Act and are classified as "vulnerable with declining populations" under IUCN's Red List. Polar bears' habitat rings the Arctic south of 88˚ latitude. Most of this area is sea ice from which bears hunt seals, although the breakup of sea ice over the summer forces some bears to move north, to pack ice, or onto land. More often, it is subadult males that are pushed to these less ideal conditions, where they live, in part, off stored fat reserves.

When bears switch to the tundra in some areas, they may enter the nesting grounds of snow geese. Goose eggs and developing embryos are a highly nutritious source of food to opportunistic foragers. Although geese populations were in decline in the early 1900s, the population rebounded and expanded. There are now too many geese for the Arctic to support in the summer, mainly because their over-wintering habitat has increased to cover the northern plains, where they eat waste corn and forage in rice fields.

Polar bear and snow geese populations come into contact in the Hudson Bay. Here, some bears routinely live on land for 4-5 months of the year, subsisting on fat reserves. The new research shows that the effects of climate change will bring additional sources of food as the movement of both populations begins earlier each spring. Rockwell and his graduate student, Linda Gormezano, calculated that the rate of change in ice breakup is, on average, 0.72 days earlier each year, and that hatching time is also moving forward by 0.16 days each year. Current trends indicate that the arrival of polar bears will overlap the mean hatching period in 3.6 years, and egg consumption could become a routine, reliable option. At this point, a bear would need to consume the eggs of 43 nests to replace the energy gained from the average day of hunting seals. But within a decade, because timing changes would put bears in contact with even more nests with younger embryos (younger embryos are more nutritious), a bear would only need to consume the eggs of 34 nests to get the same amount of energy.

I wonder if this would have a substantial impact on the snow goose population. Only time will tell.

Counting Birds for the Lower Hudson CBC

As I mentioned in a previous post, on Sunday I participated in the Lower Hudson Christmas Bird Count. I traveled up with my mother and sister. We joined three other birders early in the morning to cover the Liberty State Park portion of the count.

The Lower Hudson CBC is somewhat unusual in that it crosses state boundaries, with observers covering sites on both sides of the Hudson River. In New Jersey, the count covers the Meadowlands, Jersey City, the Palisades, and parts of towns along the western edge of the Hudson. In New York, there are observers in Central Park, the Battery, Riverside Park, and elsewhere. Lower Hudson has a link to one of the oldest counts, as the first Christmas Bird Count was conducted in Central Park.

Despite our smaller numbers, New Jersey birders found 100 species of birds on the western side of the Hudson, plus two more count week species. The total included some species that can be difficult to find in urban landscapes, such as Rough-legged Hawk, American Kestrel, Virginia Rail, and Short-eared Owl. It also included some late lingering species, like Great Egret, Greater Yellowlegs, Gray Catbird, and Marsh Wren. Plus there were a few westerners like Orange-crowned Warbler. I have not seen any full results from the New York portion of the count, but I understand that they found an immature Red-headed Woodpecker, among other birds.

Liberty State Park is so named because only a little over 600 yards of water separate it from the Statue of Liberty, while only about 400 yards separate it from Ellis Island. The park consists mainly of grassy lawns, which are great for finding open-country birds, but not much else. The park also has a restored marsh and a shrubby (but toxic) back area, which both provide opportunities for finding a more diverse set of birds.

We started out searching for waterfowl on the southeastern corner of the park, which looks out over Upper New York Bay. In addition to the flocks of 650 Brant and 400+ Canada Geese, we found a Canvasback, some Common Goldeneye, and many Bufflehead. That corner of the park also had a flock of about two dozen Horned Larks in the grass. Our next stop at the restoration area produced a selection of dabbling ducks: Gadwall, American Black Duck, American Wigeon, Northern Pintail, and Green-winged Teal, as well as a solitary American Coot. A Common Loon tried to sneak past behind us, but since I had gotten separated from the rest of the group I caught sight of it as it flew overhead. Brush around the nature center also had a smattering of sparrows – mostly Song, but also a Field and several Swamp Sparrows.

We spent the rest of the morning tramping around the park's back area looking for woodland species. While we did not find our target birds – Wild Turkey, American Woodcock, and Long-eared Owl – we did find some pretty cool birds. For example, there was a flock of around eight (!) Hermit Thrushes all of whom were very talkative. Then there were Fox Sparrows, always a treat. Plus, we flushed a Wilson's Snipe – a species we did not expect, and the only one seen in the New Jersey portion of the count.

For the afternoon we visited a housing development for a different angle on the bay, and a different look at some mudflats. That stop produced our only Yellow-rumped Warblers and Northern Shovelers of the day. It also gave us killer looks at a lingering Dunlin. The rest of the day we spent mopping up – back to the marsh to find Killdeer and a Black-crowned Night Heron, to a nearby field to look (unsuccessfully) for Snow Buntings. Our last birds for the day were two American Tree Sparrows.

Our group finished with 61 species in about ten hours of birding. Not bad at all for an area as heavily urbanized as Jersey City in the middle of December.

For more on a different section of the count, see the Meadowlands Blog.

Rock Creek Park CBC

Washington-area readers who are interested in participating in a Christmas Bird Count might consider joining the Rock Creek Park sector this weekend. Possible birds include wild turkey, northern harrier, and great horned owl, in addition to the park's more common winter residents. Follow the link to learn more.

Political Meddling Undermines ESA Enforcement

When Obama's administration takes power in January, they will have a real mess to clean up. This week the Interior Department released a 141-page report on political interference by Bush's appointees. The investigation focused on the actions of Julie MacDonald, an Interior official who frequently forced the Fish and Wildlife Service to alter endangered species or critical habitat designations.

In one case, the Fish and Wildlife Service was trying to identify which counties should be included in the critical habitat designed as important for the survival of the vernal pool species. These are plants and animals that rely on the seasonal wetlands once common throughout the Central Valley.

MacDonald directed that "huge chunks of critical habitat" be excluded, based on the apparent economic impact.

"MacDonald made math errors of an order of magnitude that led to the exclusion of critical habitat based on the erroneous calculations," one Fish and Wildlife Service official told investigators.

The vernal pool critical habitat errors led to the Fish and Wildlife Service being sued. The agency lost, was forced to pay attorneys fees and had to spend several hundred thousand dollars doing the work all over again, investigators noted.

"MacDonald's zeal to foster her agenda caused significant harm to the integrity of the Endangered Species Act decision-making process," investigators concluded. "Moreover, her actions resulted in the untold waste of hundreds of thousands of taxpayer dollars in unnecessary litigation."

While MacDonald has received most of the negative attention surrounding the Bush administration's endangered species policies, it seems to me that she was implementing the preferences of people higher up in the administration. It is notable that, even after she left the department in May 2007, the US Fish and Wildlife Service still has not designated any more species under the Endangered Species Act, despite ample evidence of species needing protection. The last year has also seen the publication of rules weakening the Endangered Species Act. Of course, the king meddler in endangered species decisions is Dick Cheney himself. MacDonald is simply one aspect of a blighted administration.

Environmental Nominees

Obama announced most of his energy and environment appointees yesterday evening. They are:

• Steven Chu for Department of Energy
• Lisa Jackson for Environmental Protection Agency
• Nancy Sutley for White House Council on Environmental Quality
• Carol Browner for assistant to the president for energy and climate change

Chu looks like an inspired choice. It will be a major change to have someone with his depth of knowledge about energy running the department. It is encouraging that he is concerned with climate change and wants to improve energy efficiency. Lisa Jackson has inspired some controversy but seems to be far better than the last New Jerseyan picked for the job. In addition to her experience in the Clinton White House, Carol Browner chairs Audubon's board of directors. Nancy Sutley also has an interesting background. All told, the next four years ought to be a lot better than the previous eight.

The nominee to head the Interior Department has not been announced, but it appears to be Ken Salazar. From what I had read about him, Salazar seems an improvement over some of the other picks being floated, but not nearly as exciting as Raúl Grijalva would have been. The good news is that he opposes oil drilling in Arctic NWR (no more annual battles!) and oil shale development. The latter practice is a major killer of birds in the boreal forest and would probably have similar results if introduced to western states. He also has a good voting record.

Counting Day

Today marks the beginning of the Christmas Bird Count season, which runs from December 14 to January 5. I will be participating in at least two this year: today's Lower Hudson CBC and the Raritan Estuary CBC on December 28. Each count works slightly differently. Some (like Washington, DC) have loads of volunteers. Others have rather small teams covering large amounts of territory (such as Raritan Estuary). This will be my first time participating in the Lower Hudson CBC, which covers parts of Hudson and Bergen Counties, such as the Meadowlands, Liberty State Park, and the cemeteries of Jersey City.

CBCs are a lot of fun, so considering signing up for one in your area. If there is not one in your area, you can always start one.

Review: Birdwatcher: The Life of Roger Tory Peterson

Roger Tory Peterson is probably the most famous birdwatcher of the 20th century. I recently had the pleasure of reading a new biography of Peterson by Elizabeth Rosenthal, Birdwatcher: The Life of Roger Tory Peterson. The book is based on interviews with many people who knew Peterson, as well as Peterson's own writings. Birdwatcher is the most thorough account of Peterson's life that I have read so far. It covers his entire his, from childhood to death.

Peterson's career spanned several generations and multiple decades. When Peterson was coming of age as a naturalist, market hunting, including hunting of raptors at migratory concentration points, was still common; field guides were unsuitable for easy field identification; and bird watching was still in its infancy. More than anyone else, Peterson influenced the transformation of bird study from a pursuit of specialists to a popular pastime. His field guide, first published in 1934, simplified the identification process such that each bird could be identified by noting a few key field marks. Peterson's field mark system, illustrated with schematic drawings, set the standard for future field guides. In future years, the expansion of his field guide series opened better understanding of not just birds, but also insects, flowers, trees, and many other taxa to the general public. He influenced the growing environmental movement not just through his field guides, but also through his writings in popular publications such as Audubon magazine and Bird Watcher's Digest, as well as through direct contact with naturalists in younger generations.

While many of the events were familiar to me – his childhood in Jamestown, his naturalist publications, his wartime service – many were not. In particular, I was pleased to learn that Peterson increasingly used his fame in later life to promote conservation. His travels abroad were designed to raise awareness of the places he visited, and many of them resulted in specific conservation actions or helped raise funds to purchase critical habitat. In this country, he helped arrange funding for some of the research that connected raptor declines in Connecticut with DDT.

To her credit, Rosenthal does not shy away from less attractive aspects of Peterson's biography. For example, his family life was extremely strained. His second wife, Barbara, seems to have left him out of frustration with her role as his unpaid secretary and social manager, even years after Roger achieved fame and fortune. His third wife, Virginia, seemed to shut out his children from his second marriage; how much Roger attempted to fix the problem is unclear.

The book would be stronger without the discussion of whether Peterson's paintings should be considered art. Answering that question would require a better explanation of the categories of "art" and "illustration," and why they should be considered distinct (if at all). The discussion is further muddled by the reliance on art dealers and other wildlife painters rather than art critics or historians who might be able to compare Peterson to his artistic contemporaries. I am not entirely sure what is at stake in that argument anyway since Peterson's reputation will ultimately rise or fall on the basis of his contributions to ornithology and conservation rather than his artistic efforts.

Some portions could stand to be more concise. In particular, chapters dealing with Peterson's middle and later years could probably have left out some material without losing much substance. Since the source material included many interviews, the narrative style occasionally becomes chatty; this may or may not bother a prospective reader.

Overall, Birdwatcher is a strong and thorough biography of Roger Tory Peterson. Even those familiar with Peterson ought to learn something from it. This book's publication is particularly timely given that this August marked the 100th anniversary of Peterson's birth. It is a good time to reflect on how far we have come since August 28, 1908, and where birding and the environmental movement might be going.

• A bird species's clutch size depends on its life history and environment. For example, cavity nesters and species in temperate environments have larger clutches; longer-lived species tend to lay fewer eggs.
• A satellite study of snowy owls found that some spend their winter on sea ice. What they are doing at sea is not entirely clear; one possibility is hunting sea birds like eiders. Other owls migrated long distances from their breeding grounds.
• Breeding birds in the Great Plains are losing habitat as farmers clear fragile land to plant more commodity crops to take advantage of high prices and federal subsidies.
  
• Predation from mice appears to be a major cause of decline for the Tristan Albatross and Gough Bunting, both endemic to Gough Island in the South Atlantic. The albatrosses also suffer from longline fishing.

Government-sponsored Greenwashing

The third article of the Philadelphia Inquirer series on the EPA under the Bush administration deals with a program called Performance Track. This program, begun under the Clinton administration, was designed to encourage companies to improve their environmental impact voluntarily. If a company meets a series of goals, it gets positive publicity and recognition from the EPA, along with other benefits. In theory, this should give companies enough incentives to behave well (beyond the threat of enforcement) . Under the Bush administration, the program has been so poorly administered that it is difficult to determine whether member corporations are actually meeting their goals.

As early as 2005, internal records show, EPA enforcement officials discovered violations by Performance Track companies, and began to ask questions about compliance and corporate promises.

In 2006, these EPA enforcement officials prepared a confidential and comprehensive analysis of the program. The Inquirer obtained a copy.

"The data in this analysis clearly show that there is considerable non-compliance among [Performance Track] facilities and that many members who are widely touted as meeting or exceeding regulatory requirements actually do not," the analysis said.

At the time, a check of enforcement records showed six Performance Track companies with serious environmental violations and 43 with other pending formal enforcement actions....

Last year, an EPA inspector general's audit confirmed some of the enforcement division's findings. "EPA had hoped to achieve ambitious goals through Performance Track, but EPA cannot show how its program can lead to the desired outcomes," auditors wrote.

Only two of the 30 companies sampled by the inspector general met all four of the anti-pollution goals they set.

Coglianese's extensive research, some of it EPA-funded, said the EPA's claims that Performance Track is beneficial to the environment are simply rhetoric. There are no data to prove this, the Penn dean said.

In fact, said Coglianese, data show that there's little difference between the environmental records of companies that join and companies that don't.

The difference: "Companies who join Performance Track seem to do so because they seek attention," he said. They want that green EPA seal of approval....

Another critic, the advocacy group Environmental Integrity Project, studied Performance Track members' public toxic release reports. It found that seven large factories increased emissions after they joined the program - by a total of two million pounds between 2000 and 2004.

EPA officials said the study contained errors - though they have since decided to review such data to prevent this from happening again, they say.

But an Inquirer review shows that some of the same Performance Track companies that Environmental Integrity raised questions about two years ago continue to increase toxic emissions. According to EPA's latest Toxic Release Inventory data, emissions at the Verso Paper factory in Jay, Maine, have increased 160 percent since 2001, to 1.9 million pounds.

Performance Track relies on states, which enforce most federal environmental laws, to ease regulatory oversight of its members. At least 19 states partner with the program, but others remain wary - including Lisa Jackson, New Jersey's former Department of Environmental Protection chief and now chief of staff to Gov. Corzine.

"For a long time, they tried to pressure us to partner and we said no," Jackson said in October, before she became an Obama transition adviser. "I think it's just one of those window-dressing programs that has little value."

Francine Carlini, regional director for air quality in Southeastern Pennsylvania, said EPA had asked the state to dispense with some of its usual regulatory duties.

"It all sounds good . . . but you can't give away the store to get that done," she said. "Imagine if we went to a landfill and they said, 'We're in Performance Track,' and we said we wouldn't inspect them. There is kind of a disconnect here. That's the problem."

The article cites several egregious examples of Performance Track members that soiled their environment. One was a chlorine plant that emits 420 pounds of mercury each year. In another case, DuPont facilities remained in the program even after the parent corporation paid a $10.25 million fine for hiding evidence of the harmful health effects of perfluorooctanoic acid (released by many of its plants and used to manufacture Teflon) for two decades. Monsanto has also been lauded under the program despite serious violations.

Instead being used to ensure compliance, the program's $4.7 million budget seems to go towards providing government-sponsored P.R. for the member companies.

Over the last four years, Performance Track has paid two outside consulting firms more than $4.2 million.

Last year alone, records show, EPA paid ICF Consulting of Fairfax, Va., nearly $700,000, including $249,875 for member recruitment and $311,287 for "branding, outreach and communications."

The other consultant, Industrial Economics Inc. of Cambridge, Mass., has received $2.7 million to help run the program and operate its hotline, records show. Spokesmen for ICF and Industrial Economics declined to comment for this story.

In 2007, EPA placed public service announcements touting its corporate members' accomplishments in Forbes, Fortune and Business Week.

One full-page ad claimed that Performance Track members cut water use by 3.5 billion gallons: "That's a big drop in the bucket," the ad said.

There should be higher priorities for the Obama administration to reform at the EPA – with implementing climate change solutions at the top of the list. However, this program seems like it could be valuable with higher standards for membership and compliance (and perhaps some assistance for companies to meet their goals) – more substance and less hype. At the very least, it is encouraging that one leading candidate to head the EPA for the next four years is already well aware of Performance Track's flaws.

Desired Life Bird Meme

Corey at 10,000 Birds asks for everyone's top five desired life birds. This is a question I have answered before, but since I have seen some of those, and since some priorities have changed, the list could use some updating. Given that my life list is relatively short (I only passed 300 earlier this year), it is hard to narrow a wish list down to just five, but here is a try (subject, of course, to future revision).

1. Northern Goshawk – I had a few possible/probable goshawk sightings in Cape May, but what I would really like is one I can confirm with my own eyes.
2. Golden-winged Warbler – This is the last of the widespread eastern warblers (i.e., excepting Kirtland's) that I have not seen.
3. Any Crossbill – I have long been fascinated by the idea that a bird's mandibles could cross without the cause being a genetic defect. (Perhaps this winter?)
   
4. Any Godwit – These are pretty cool looking birds and have impressive migrations.
5. Painted Bunting – Like the crossbills, it looks like something that should not exist in nature (more like a color scheme I would have concocted when I was five).
   

I am not tagging anyone, but if you want to pick up the meme, go right ahead.

Stephen Johnson and the Misuse of the EPA

Via Thoughts from Kansas, I learned of a major new series of articles at the Philadelphia Inquirer on the state of the EPA. The first article of the series is a profile of Stephen Johnson, the current EPA administrator. Johnson's tenure has been noteworthy for controversy over a multitude of issues, from political interference with scientific research to denial of California's emission standards to foot-dragging on climate change. The Inquirer article has a behind-the-scenes look at one of the more egregious incidents involving Johnson, in which he was initially set to rule that greenhouse gases were causing climate change, that climate change endangered public health, and that the United States was a major contributor of greenhouse gases.

At 2:10 p.m., Associate Deputy Administrator Jason Burnett e-mailed the climate-change draft to the White House as an attachment.

What happened next became Johnson's defining moment and cemented President Bush's environmental legacy, serving as the low-water mark of a tumultuous era that has left the EPA badly wounded, largely demoralized and, in many ways, emasculated.

White House aides - who had long resisted mandatory regulations as a way to address climate change - knew the gist of what Johnson's finding would be, Burnett said. They also knew that once they opened the attachment, it would become a public record, making it too controversial to rescind. So they didn't open it.

They called Johnson and asked him to take it back.

The law clearly stated that the final decision was the EPA administrator's, not Bush's. Johnson initially resisted - something Burnett admired - but ultimately did as he was told.

Outraged, Burnett resigned.

In July, Johnson issued a new, censored version, a pale imitation of the original climate-change document.

The old muscular language - including key sentences about U.S. car emissions and the irrelevance of any lingering doubt - was gone. Most of all, the new document no longer declared global warming a danger to public welfare. The move effectively postponed any strong action on climate change well into the next administration.

Aside from his support for deregulation, Johnson shares at least one other trait with White House officials – public professions of faith (Johnson is an outspoken evangelical Christian who praises "the moral compass, that Taylor [University] offered") exist side by side with questionable ethics.

Clearly, Johnson has been eager to execute the Bush agenda. John D. Graham, who was the regulatory guru of the White House Office of Management and Budget from 2001 to 2006, said one of Johnson's biggest accomplishments as assistant administrator was the repeal of a Clinton-era ban on human pesticide testing....

The human testing studies were not perfect; some did not meet modern ethical standards, Graham said. But advocates were pushing for a ban regardless of their scientific value....

One of the new human tests was the Children's Health Environmental Exposure Research Study (CHEERS). Funded with $2 million from the chemical industry, CHEERS proposed to record the effects of household pesticides on low-income children in Florida. EPA gave participating families $970, a video camera to record exposure, and a CHEERS T-shirt, calendar and baby bib. EPA scientists would collect urine samples and the children would wear a watch-size sensor one week each month.

Several Democrats were aghast. Boxer and other Democrats put a public hold on his nomination.

"Ethics 101: Testing pesticides on small children and infants is wrong," Boxer said. "This is sick. It's a sick, sick thing."

EPA officials said that the senators were overreacting, that CHEERS merely paid families already using pesticides to monitor their children. Johnson, who began his EPA career in the pesticide office, said that although EPA had no improper ethical intent, it could no longer overcome such an appearance.

He canceled CHEERS - though not other human testing programs - and the senators removed the hold on his confirmation.

There is plenty more in this article about Johnson's background in private industry, his rise to prominence under the Bush administration, and coverage of his other controversial decisions as administrator. Even other Republican EPA administrators believe that Johnson's conduct has been overly political and insufficiently independent. The EPA, like other government agencies, is mandated to follow the best available science when it comes to issues like climate change and public health. It is fairly clear that Johnson used his position to stall for time and punt major decisions to the next administration, rather than obey his legal mandate.

Christmas Presents

The outgoing administration is working overtime to finalize ideologically-driven regulatory changes. To wit:

• Appalachian drinking water will come with extra heavy metals now that coal companies need no longer meet clean-water requirements when they fill valleys with surface mining detritus. (via)
  

  Under the changes in the final rule, EPA would consider mining valley fills incompliance [sic] with water quality standards if mining operators obtained "dredge-and-fill" permits from the U.S. Army Corps of Engineers. But, the standard for obtaining such a permit allows a greater level of damage than would be permitted under OSM's previous version of the buffer zone rule....
  
  Coal operators already can obtain variances to mine within the 100-foot buffer. To do so, though, companies must show that their operations will not cause water quality violations or "adversely affect the water quantity and quality, or other environmental resources of the stream."
  
  For years, the OSM and various state mining agencies have interpreted the buffer zone rule to not apply to valley-fill waste piles that bury streams.
  
  In 1999, then-U.S. District Judge Charles H. Haden II concluded that the rule did apply to valley fills. That decision was overturned on appeal, but federal regulators and the coal industry still moved to rewrite the rule.

• If you have a loaded firearm, you can take it to your favorite national park!
  

  As expected, the Interior Department decided to scrap its longtime ban on loaded weapons. Under the new regulation, individuals will be allowed to carry loaded, concealed weapons in parks or wildlife refuges if they have state permits to carry concealed weapons in the state in which the national park or refuge is located.
  
  Under current regulations, firearms in the national parks must be unloaded and inoperable. That means they must have trigger locks or be stored in a car trunk or in a special case....
  
  National parks range from Yosemite, Yellowstone and the Grand Canyon to the family home of the wife of Ulysses S. Grant in eastern Missouri and New York's Lower East Side Tenement Museum.
  
  Bill Wade, the president of the Coalition of National Park Service Retirees, said the new regulation would allow concealed, loaded firearms at 388 of 391 park sites. Only the three national parks in Wisconsin and Illinois, which don't issue concealed carry permits, are excluded, he said.

• There is still the issue of the revisions to the Endangered Species Act, which were recently finalized.
  

  The latest version of the rule goes further than the language Interior Secretary Dirk Kempthorne issued in August by explicitly excluding climate change from the factors that would trigger an interagency consultation. The move is significant because the administration has listed polar bears as a threatened species under the act on the grounds that their sea-ice habitat is shrinking, but Kempthorne has repeatedly argued that this move should not trigger a federal curb on greenhouse gas emissions linked to the melting of sea ice.
  
  The rule states: "Federal agencies are not required to consult on an action when . . . the effects of such action are manifested only through global processes and (i) cannot be reliably predicted or measured at the local scale, or (ii) would result at most in an extremely small, insignificant local impact, or (iii) are such that the potential risk of harm to species or habitat are remote."

Meanwhile, Bush also pardoned someone convicted of poisoning bald eagles. He has been very busy, and he still has a month and a half to work mischief.

Bird news

• Northern spotted owls are rapidly disappearing from their former range. There may be as few as 5,000 across British Columbia, Washington, and Oregon, and the population is down about a third since the 1990s. In addition to habitat loss, spotted owls have been affected by barred owl incursions. Meanwhile, a last-minute regulatory change would open 1.8 million acres of spotted owl habitat for logging. A lawsuit seeks to block the changes.
  
• A study of nesting bald eagles in the Catskill Mountains found elevated mercury levels in both adults and nestlings.
  
• While starlings in this country are often regarded as pests, in their native U.K., there is concern that starlings might disappear in the near future. The precise cause of their decline is unknown.
• The RSPB is searching for the rare slender-billed curlew, once common but now feared extinct. The last sighting was in 1999.
  
• A recent expedition found 1,224 species around the South Orkney Islands near Antarctica – more species than are known to occur around the Galápagos Islands and several other tropical locations.
• White-tailed eagles, closely related to North American bald eagles, may return to England after a 200-year absence.
• New York recently became the ninth city to sign the Urban Conservation Treaty for Migratory Birds, which requires its signatories to undertake educational and habitat preservation projects.
• Climate change could destroy habitat for 75% of the big penguin colonies in Antarctica.

Bird Surveys and Background Noise

I recently came across an article (originally noted here) with some discouraging news about bird surveys. One of the key datasets used to measure North American bird population trends is the Breeding Bird Survey, in which observers conduct routine point counts along standardized routes. These point counts involve some visual observation, but most identifications are made by ear. A study found that even experienced observers tended to underestimate when identifying birds in the presence of background noise.

In order to explore these questions, Simons and others worked to develop "Bird Radio:" a series of remotely controlled playback devices that can be used to accurately mimic a population of singing birds. Researchers could then control variables, such as background noise, to see whether it affected birdwatchers' ability to estimate bird populations.

The study found that even small amounts of background noise, from rustling leaves or automobile traffic, led to a 40 percent decrease in the ability of observers to detect singing birds. What's more, said Simons, "we also learned that misidentification rates increased with the number of individuals and species encountered by observers at a census point." In other words, the researchers found that traditional means of estimating the abundance and diversity of bird species are flawed due to complications such as background noise and the accuracy of the data observers collect on surveys of breeding birds.

But the Bird Radio research also points the way toward possible solutions. Simons explains that the Bird Radio findings are helping researchers develop better sampling methods and statistical models that will provide more accurate bird population estimates. For example, researchers are attempting to identify data collection methods that will help account for background noise or other outside factors in estimating bird populations.

The result may call into question the numbers undergirding some recent State of the Birds reports, which rely heavily on data from the Breeding Bird Survey and Christmas Bird Counts. Those surveys are used for other reports and management decisions as well, so it is important that they be as accurate as possible, so that conservation money is going to the right place. I hope that the study authors find a better way of sampling, and that they share it with the rest of us who participate in such surveys.

End of the Season

The end of the raptor banding season came over the weekend. We closed the last station a day early due to the threat of rain – rain that did materialize. Over the course of the season, banders recorded 2,155 raptors. Of that total, I probably handled around 500 of them in the course of retrieving hawks from nets and doing public demos. The season totals are on the project's weekly updates page. In the course of the season, I learned how to capture raptors, how to handle them (mostly without getting footed), and how to process and band them. I am hoping to learn songbirds as well in the near future.

My season in Cape May has come to an end as well. During the three months I spent at the Cape, I saw 173, including nine life birds. My stay there was extremely productive from a birding perspective, even though I had very little time to explore the Cape's hotspots.

Normal blogging will resume slowly this week. In particular, I hope to restart the Loose Feathers series this Friday.

Birding Notes

While I have been neglectful of this blog over the past two weeks, I have been seeing some good birds.

Last week was phenomenal for red-tailed hawk migration. At a single banding station we banded 102 for the week, including 36 on one day (tying a single day record for the project), and 27 and 24 on two other days. It appears that a lot of buteos were lingering north of here, until a series of strong cold fronts (and possibly some snow) pushed them south. The last two weeks have also brought three red-shouldered hawks, a peregrine falcon, and a merlin – all rather late migrants – to our station. The hawk watch had similarly impressive red-tail numbers last week.

At the same time that red-tailed hawks were barreling through, fox sparrows started to arrive in large numbers. I have been hearing their songs all over the island this week. At first the song confused me because it starts off like a cardinal's but does not end like one, and at times sounds almost like an oriole. Eventually I figured out what it was. Speaking of orioles, there are still some around here, including one that I saw outside of where I am staying.

Owls are also migrating through. Yesterday I followed a report to find a long-eared owl. It was mostly obscured by branches, but still identifiable. A northern saw whet owl was reported from the same location, but I did not find that species. Had I stayed and checked each tree thoroughly, I might have located the tiny bird, but I did not want to create too much disturbance in that grove.

This afternoon at the Beanery, I encountered a Cooper's hawk, a sharpie, a red-tail, a kestrel, and a merlin. That's not bad for a walk of only about an hour. Plus there were several sparrow species – all of which gave great looks in the low-angle sunlight – and a few meadowlarks.

Happy Thanksgiving! I'll be back to regular posting fairly soon.

Taking Aim

Background here.

Adult Male Harrier

We band very few adult hawks in Cape May, as most of the coastal migrants are hatch year birds. This is the first adult male northern harrier that I have seen in the hand; I still have not held an adult female.

Note the bright yellow eyes and gray facial disk.

While the breast is gray, the belly is white (with light brown barring).

The back is darker gray than the wings.

These birds stand out at a distance, so much so that they seem less in tune with their surroundings than the female and immature forms, which take the color of marsh and meadow grasses. Male harriers seem to belong on the tundra, like snowy owls or gyrfalcons.

How Many Rare Birds?

David Sibley has been running an interesting series of posts on how many rare birds are out there versus how many we find.

1. How many do we miss?
2. How many do we find?
3. Rare birds and the internet

The second post was partly in response to an interview that I did with Nick at the Birdist. I had already been changing my opinion somewhat since doing that interview because of my experience at Cape May. While there are a lot of birders here, it seems that the same few places get the bulk of attention from most birders, while other sites get less coverage. So a lot of rare birds could be slipping through, even here.

Hawk Personalities

N8 is right that bird species show different temperaments in the hand, and this holds for raptors as well as the songbirds that he helps to band. Among raptors, larger birds tend to be calmer than smaller birds. This is not always true, as bald eagles and northern goshawks both have reputations for being a bit high strung, but it holds for most raptor species.

Among buteos, red-tailed hawks are fairly docile, which is a good thing since their legs are powerful and their talons are particularly large. They just sit still with their mouths open and their wings spread wide until it is time for release. Red-shouldered and broad-winged hawks will try to bite and are often successful. (Bandages and hand wipes are very useful in a banding station.) The buteo-like golden eagle is also remarkably calm; both golden eagles this week tolerated many curious onlookers and extra measurements without struggling at all.

Accipiters are more likely to struggle and bite, though the majority of both sharp-shinned and Cooper's hawks will tolerate the handling necessary for banding. I have been bitten numerous times (and occasionally footed) by both of the common accipiters. Sharpies often act tough despite their small size, much more so than Cooper's hawks.

Falcons are the most high strung of all the raptors that I have handled this fall. Like N8's chickadees, they are very good at finding sensitive spots when they bite, which they do at every opportunity. They are also very flexible, especially kestrels. Both kestrels and merlins will scold during the banding process; merlins often keep scolding as they are flying away after release. Still true to the size rule, peregrines will not struggle or scream as much as the smaller falcons, but they do hiss (like a cat) and bite. Hissing makes their fish breath even more noticeable. Unlike other hawks, most falcons will perch near the banding station and try to pull their bands off immediately after release.

Those observations, of course, do not hold for all individuals of a species. From time to time we get a feisty red-tailed hawk or a calm merlin.

Sharing Checklists

EBird now allows checklist sharing, so that multiple users can submit sightings to the same checklist when they bird together.

Checklist sharing makes it possible to copy an eBird checklist to another user's account. Each user can edit the checklist to more closely match the species he or she saw that day. This allows multiple copies of the same checklist to be associated with a single birding event and ensures that we do not create unnecessary duplicates for our scientific analyses. At the same time, this gives our users the flexibility to make sure that their personal records are accurate. We are excited about this release for several reasons: 1) it will make data entry easier for eBirders that bird in groups; 2) it allow us to more accurately describe your group birding events; and 3) it provides an easy way to introduce people to eBird.

When birding as part of a group, we consider there to be two types of checklists: a Group Checklist and an Individual Checklist. A Group Checklist is the summation of the highest counts of each species seen by the group. Thus, if one person in the group sees 8 Painted Redstarts and 2 Red-faced Warblers, but the rest of the group saw 6 Painted Redstarts and 3 Red-faced Warblers, then the Group Checklist would show 8 Painted Redstarts and 3 Red-faced Warblers. When a shared eBird checklist is accepted by another member of the group, a unique Individual Checklist is created which can then be edited. In addition, a Group Checklist is automatically created that is a summary of reports by all members of the group, taking the highest value for each species from each checklist. Although each user's Individual Checklist will remain unique within his or her personal account, the Group Checklist that eBird uses for output (maps, graphs, bar charts) will be a combined checklist for all individuals.

The link has directions for how to do this.

More Golden Eagles

Yesterday was the first cold front followed by clear weather in about two weeks. As a result, a lot of birds that had been bottled up north of here started moving through. There were decent number of buteos – as many red-shouldered hawks as I have seen so far this season and some red-tailed hawks, too.

The real story were the golden eagles. One of our blinds banded a second golden eagle, also a hatch year male, but with darker wings and a narrower tail band. This was only the fourth time the project has banded more than one in a year.

Also, I hear the hawk watch had a record day for golden eagles. (Update: More on the record day here and here.)

Golden Eagle

We banded one of these yesterday. It was the first of the season to be banded, though nine have been counted from the hawk watch. This bird may have been seen from the hawk watch on the same day.

Snowy Owls, Part 2

Some bloggers north of here went to see snowy owls that have already been reported in the northeast.

Christopher went to see the snowy owl at Plum Island (MA).

Tom visited the snowy owl in Norwalk (CT).

Remember, if you do follow a snowy owl report and find the bird, keep a respectful distance and do not interfere with its normal activities.

Deformed Bills

Raptors with deformed bills are turning up along the West Coast.

Hundreds of other birds are not so lucky. The most commonly affected seem to be raptors and crows. But it’s easy to find distressing pictures of other species... from chickadees to hummingbirds....

Manthey surveyed fish and game departments and wildlife rehabilitation centers across the region. Reports of affected birds stretch from California to Alaska. Sightings appear to be concentrated west of the Cascades. It gets sketchier the further east you go; for example, nothing in Idaho. Among researchers, this has become known as “long billed syndrome.”

The cause of the deformity is undetermined.

Veterinarian Lindsey Oaks studies animal diseases at the university in Pullman. Other researchers are based at the Alaska Science Center in Anchorage and Oregon State University. Dr. Oaks says “many, many things” could cause a bird’s beak to grow abnormally.

Oaks: “Since there are no inflammatory cells, no evidence of infectious disease, it sort of makes you want to think about toxins. But of course there are all kinds of toxins, all different sorts of things. There is nothing consistently associated with this type of disease that we’re aware of. So it presumably would be something new.”

Oaks says genetic defects could play a role as well. The affected birds are a mixture of residents and migrants, which adds to the mystery....

Oaks hopes to unravel the mystery by figuring out what’s happening at the molecular level and then working backwards. So far, he’s found unusual proteins in affected birds that are not present in normal bird beaks.

I hope that the cause is found soon if this is being caused by an environmental contaminant or a contagious disease.

Murre

After several days in which rain shut down most banding activities, we finally reopened all of the banding stations yesterday morning. Unfortunately, the results were still not good. The "best" bird of the day (at my station, anyway) was a purple berry-stained sharpie. (Unfortunately, I did not get photographs of it.) Midway through the day, we got a call about a rare bird being seen at St. Mary's Jetty - a thick-billed murre.

Normally found off eastern Canada and New England, this alcid comes this far south only rarely. So we closed up and went down to see it. The murre was floating in the surf about 10-20 feet offshore. For a long time it hung around the jetty; then suddenly it started swimming westward towards the bay. It appeared to be injured, and gulls (both herring and great black-backed) would occasionally harass it. Eventually it grew more distant from land and disappeared.

While we were standing on the beach, with a flock of other birders, some other interesting birds passed by, including a parasitic jaeger, Bonaparte's gulls, northern gannets, and a lot of royal terns.

Snowy Owls on the Way?

Some bloggers in Connecticut are reporting that there has been a spurt of snowy owl sightings in their state. From sphere:

From Frank Mantlik:
11/05 - Norwalk, Calf Pasture Park -- 6:35-6:50am (at least) SNOWY OWL on ground in parking lot, located with the help of a few crows. I walked in, as gate was not opened till 6:50.

From Mardi Dickinson, Larry Flynn, et al:
11/05 - Norwalk, Calf's Pasture Beach Park -- 9:52 SNOWY OWL continued to the right of pier roosting on jetty rocks. The owl stayed in that area for most of the day. The Owl did however fly several times back in front of the stone wall, the grassy area next to the pier, and the fence along the path with incredible looks and photographs were taken. Sara Zagorski and I stayed till 5:15PM watching the owl sitting on the post fence looking around gearing up for it's evening hunt for food. Not a care in the world!

From Bev Propen:
11/05 - Stratford, Stratford Point -- 1 SNOWY OWL. I could only stay from 10:30AM-11AM, but I got magnificent views of this majestic bird; Beautiful gold/yellow eyes, and some dark streaking on its crown. Blood still on its claws from a recent hunt.

If this is an irruption year, as some are calling it, there is a good chance for snowy owl sightings here in New Jersey or even farther south. Keep an eye out for big white spots in open areas.
