The lake lay blue below the hill.
O'er it, as I looked, there flew
Across the waters, cold and still,
A bird whose wings were palest blue.
The sky above was blue at last,
The sky beneath me blue in blue.
A moment, ere the bird had passed,
It caught his image as he flew.

Yesterday morning I met with a friend for a walk in the National Arboretum. It was a quiet morning, with less human activity than usual until the day warmed significantly. The birds were out, though, in good numbers. We covered my usual circuit to the Anacostia and back, with a detour through the Azalea Gardens.
The biggest surprise of the day was an eastern meadowlark near the Capitol columns. I had heard of meadowlark sightings there before, but I had never actually seen one at the Arboretum. It rose up out of the grass and flew to perch in a shrub as we walked a path through the meadow. It had its back to us, so the yellow and black breast was not visible, but the shape and white tail feathers gave away its identity.
At the river we had several common mergansers and a gadwall, plus some of the usual suspects. A belted kingfisher cruised along the river. One red-tailed hawk flushed from the trees in the meadow at the south end of the trail.
Eastern phoebes were still around - and still finding insect food - despite last week's cold snap. A hermit thrush foraged in the underbrush on one of the Azalea Garden trails.

- At least 600 birds have died and many more have been contaminated as the result of an oil spill from a ship that was run ashore near Devon, UK. The ship was grounded deliberately following damage from a storm. Wildlife agencies are still looking for birds affected by the spill.
- A study by Wetlands International showed that waterbirds continue to decline. Of 878 species studied, 44% has significant reductions in population since 2002. The major area of concern right now is Asia, where economic growth has led to increased urban sprawl and reclamation of wetlands. In other cases, Asian wetlands are threatened by pollution.
- Over the past year, 71,000 waterbirds have been tested for highly pathogenic avian influenza in North America, but so far no positive cases have been identified.
- Cuyahoga County in Ohio plans to build 4-10 wind turbines about three miles from the shore. The plan is raising questions regarding whether these turbines will be safe for birds. One issue will be whether deaths at an open-water site can be monitored.
- The Pennsylvania Game Commission is studying migration routes of golden eagles through the state to determine the best way to avoid collisions between those birds and wind turbines.
- Here are some tips for feeding birds in winter. It covers different types of food and feeders.
- Eagles at Blackwater NWR have laid an egg and are incubating it. Here is the live webcam.
- BirdLife and Nature Iraq collaborated to produce a field guide for the birds of Iraq. The guide features 387 species and is the first comprehensive field guide in Arabic. (Via Wildbird)
- A hunter in Florida shot a duck, but somehow it survived both the shooting and two days in the refrigerator. Now it is recovering in an animal hospital.
- Ski trails, especially in forested areas, tend to reduce bird diversity.
- A Houston homeowner was caught raising about 100 birds for cockfighting.
- Bats fly more efficiently than birds because their wings are flexible and produce more lift and maneuverability.

I and the Bird has gone Down Under again to be hosted by A Snail's Eye View. Snail introduces us to an early guide to Australian birds, What Bird Is That? by Neville Cayley. Go visit I and the Bird #41 for the best in recent bird-blogging.
As I have mentioned previously on this blog, this past Saturday was the C&O Canal Count. This count, in its ninth year, aims to survey bird life along the length of the C&O Canal, which runs parallel to the Potomac River for 184.5 miles from Georgetown in Washington, DC, to Cumberland, Maryland. I was one of several birders who traveled from the DC area to cover a stretch in Allegany County. Since the distance from Washington is so far, our group stayed in the Little Orleans Lodge both Friday and Saturday nights.
At dawn on Saturday there was a fresh coat of snow on the ground. This quickly disappeared as the day warmed. Predicted heavy winds never materialized on this stretch of the canal, though they did further downstream. The canal in the 130s through 150s is generally protected by high ridges and deep bends in the Potomac River. The Little Orleans team spread out to cover 3-6 mile sectors between mileposts 136 and 153. I paired with another birder to cover the area between mileposts 140 and 144.
The two of us encountered a typical winter birding phenomenon: long stretches with few birds and concentrated patches of mixed-species flocks. We saw six woodpecker species, brown creeper, winter wren, my first black-capped chickadees of the year, tufted titmice, dark-eyed juncos, eastern bluebirds, and a few large flocks of cedar waxwings. Eastern phoebe and belted kingfisher were two lingering warm weather species. Near the end of the count we spotted a subadult bald eagle seeking thermals; once it found one, it soared high into the air over the river valley. Oddly enough, the four miles we covered had few sparrows and no cardinals. For an urban birder like me, it was even more disconcerting to see only two rock pigeons and no starlings at all. An evening walk - not part of the official count - turned up a barred owl barking from across the Potomac.
On Sunday, our team from DC took a side trip to do some birding in the Green Ridge State Forest. Those spots turned out not to be very birdy, possibly because the morning was so raw. Three of us pushed on along the canal to see the Paw Paw Tunnel in mile 155. The 3,118-foot-long tunnel is impressive work, especially considering the technology available at the time. After its completion, the tunnel allowed canal boats to bypass some of the many deep bends in the Potomac River. The cut on the eastern end of the tunnel is itself worth seeing; on Sunday the sheer rock was lined with cascades of icicles, as well as overhanging ferns and conifers. A winter wren popped in and out along the rocky slope.
The three of us walked through the tunnel; when we emerged from the western end of the tunnel, snow was falling. Snow continued falling as we backed over the tunnel hill trail and along the canal. Despite the snow, we encountered some active flocks of birds, including more phoebes, creepers, chickadees, titmice, juncos, and a kingfisher. With few people out on the towpath, and no sound except for flowing water and our own footsteps, the walk was very peaceful. Snow made the canal all the more beautiful.
The weekend offered some great birding, but not so much in the numbers of species or individuals. Great birding can also consist of close-up looks at birds, looking for birds in a spectacular setting, or birding with skilled companions. All three were certainly the case this weekend.
A growing list of reported species and individuals is here. If you visit that page, keep in mind that we are still in the process of collecting data from observers and not all reports have been verified. Until we release the final report, the totals listed there should be regarded as tentative. We have set up a gallery with images from the count here.
SPECIES OBSERVED (over two days): 33

The Post this morning has an article on watching bald eagles at the Blackwater NWR on the Eastern Shore of Maryland. Here is a taste:
Still, there are whole generations of Americans who have never seen their national emblem in the wild. For them, and for all lovers of majestic birds, there is Blackwater Refuge and the surrounding tidal marshes of Dorchester County. On this soggy patch of the Eastern Shore, less than two hours from Washington, is one of the largest concentrated bald eagle populations in the country (the largest on the East Coast outside of Florida). And for the next couple of months, eagle-watching conditions are perfect: The number of birds is at its annual peak; courtship and nesting activities are getting underway; and unlike in summer, when the eagles seek the afternoon shade, they are active all day in the cool open air. Between December and March, eagle-spotting at Blackwater is about as close to a sure thing as you can get in the maddening world of wildlife viewing.Read the rest.
Most mile segments of the C&O Canal will be covered during the Mid-winter Bird Survey on Saturday. However, we still have a few open sections in western Washington County. Any birders in western Maryland or West Virginia who would be interested in covering these segments should email us at firstname.lastname@example.org as soon as possible to register.
To learn more about the purposes and past results of the survey, visit the canal count homepage.

Along with the expansion of blogging, a cottage industry has developed to turn blogs into self-published books. The latest example is not from a single blog, but from a conglomeration of blogs. The Open Laboratory is an anthology of the best writing on science-themed blogs from 2006. Posts cover diverse topics from explanations of key concepts to opinion pieces on current events to humor. Several posts are bird-related.
The anthology was conceived and edited by Bora Zivkovic, aka Coturnix, the proprietor of A Blog Around the Clock. I had a small hand in the publication since I was one of the dozen reviewers who read the nominated posts and recommended which to include. Links to the 50 posts included in the anthology are here; the full list of nominations is here.
The Open Laboratory is available as a paperback for sale at Lulu.com.
Yesterday afternoon I walked around the reflecting pool in front of the Capitol. Most of the birds there were ring-billed gulls like the birds above. There was a small flock of mallards as well. To my surprise, two lesser scaup - a male and female - flew past and landed in the middle of the pool. I think today was the first time I have seen scaup at that location.
Two red-tailed hawks were circling together over Constitution Avenue and landed on top of the Labor Department. Later I saw the two circling together again, and later still, I saw one perched in a tall willow oak on the grounds of the Capitol. Could we have a pair downtown? This will bear watching.
The Indian Museum wetlands had the usual flock of mallards. I saw that an unusual-looking duck had joined the flock again. My guess is that this bird is a mallard X black duck hybrid. It looks mostly like a black duck, but it has a green crescent running along the top and back of each side of its head.
Today's sunset was gorgeous. There was just the right mix of sun and clouds to make for a dramatic sky. I shot the picture above from next to the reflecting pool; the picture below was taken near the Senate office buildings.

This afternoon I visited the Arboretum for some birding. I was trying to cover some areas that I do not normally visit, and ended up not seeing many birds in them. So now I know why I do not bird in those areas often.
There were few real highlights today. I saw a flock of eastern bluebirds in the meadow near New York Avenue. There were about a dozen, all together. The holly area had a large flock of about 40 cedar waxwings, all chirping. When I turned to walk away, the sound stopped; I looked back, and the flock had disappeared. Elsewhere, a pileated woodpecker flew directly overhead so that I could examine its underwing patterns. I saw that one and heard pileated calls in two other spots. I wonder if the Arboretum has one pair or two. (Or more?)
My only other comment is that this afternoon was excessively warm. The cherry trees are still in bloom. The camelias and other tea trees in the Asian gardens are also blooming, but that is expected at this time of year. Dogwoods (left) are budding. I noticed one bumblebee and many moths in flight.

The Ninth Annual C&O Canal Mid-Winter Bird Survey will be next Saturday, January 20. The survey is coordinated by the DC Audubon Society and aims to survey bird life along the entire 184.5 miles of the canal. The canal is divided into 2-4 mile segments, each of which is covered by a small team of observers. Most miles are now assigned, but about thirty miles are still up for grabs. Any birders in the area who would like to participate should email email@example.com as soon as possible.

Yesterday, Grist published an opinion piece by Jenny Price that encouraged nature writers to focus more on cities to revive the connection between nature and the everyday lives of our predominantly urban population. She wants to see five questions addressed: "what and where are the wild things," "how do people use nature as resources," "how do people transform the landscapes they live in, and how does the nature ... act back," "how do different people encounter nature differently," and "how do people imagine and understand nature." (Follow the link above to see the full explanations for each of these.)
I think that it is useful to be reminded that nature is a key part of urban life, and her suggestions for themes are sound. At the same time, I think that some of what Price seeks is happening already, so that Price's frame for the column is a bit overstated. As one of the comments on the opinion piece suggests, "there is a lot of great nature writing about cities - it's just hidden." That comment referred to local resources and guidebooks. Since I am not well-read in contemporary nature writing, I cannot speak for what one would find in print. But I would venture that Price would find more urban nature writing by looking online, particularly in the blogosphere. Just among bird bloggers, I see many that are based in cities and write frequently about urban birding experiences. Aside from this blog, based in Washington, there are blogs based in a DC suburb, Chicago, Detroit, and St. Louis. And, of course, there are a boatload in New York: 10,000 Birds, Birding Life, Brooklyn Parrots, City Birder, Nova Hunter, Origin of Species, Pale Male Irregulars, and Urban Hawks. This list is probably incomplete, and there are many city-based nature bloggers outside of the birdwatching sphere. Together they help to answer at least the first of the questions Price proposes, and many work towards other One could argue that the influence of these blogs is limited, but it is not negligible, either.
This week's I and the Bird, a carnival about birds and birding, has been posted at Peregrine's Bird Blog, a birder and chef from Northern Ireland. He presents us with a feast of bird blogging links in I and the Bird #40.
I read at A Blog Around the Clock that someone declared this to be National Delurking Week. Lurkers are readers who visit a site regularly but never comment on the posts. I believe that this blog must have its fair share of lurkers since the visitor count is far, far higher than the number of comments on any given day. So, use this post to say hello. Even better, keep the spirit of the week in mind as you visit the sites linked in this week's I and the Bird!
Last year was the hottest on record in the continental United States. Temperatures averaged more than 2 degrees above normal over the course of the year, and December was the fourth-warmest on record. It was the latest in a nine-year streak of hot temperatures.
Climate experts generally do not make much of temperature fluctuations over one or two years, but Lawrimore said the record 2006 temperatures were part of a long and worrisome trend. For instance, NOAA said, the past nine years have all been among the 25 warmest years on record for the continental United States....This news has been accompanied by predictions that 2007 will be even warmer than the past two years and may set a new records.
Lawrimore said other NOAA research has found that the rate of temperature increase has been significantly greater in the past 30 years than at any time since the government started collecting national temperature data in 1895. Globally, 2005 was the hottest year on record, Lawrimore said, and 2006 was slightly cooler.
The recent hot temperatures have been blamed on climate change, El Niño, and other regional factors. The blog RealClimate recently ran a post that discussed the interaction of the various factors that affect weather patterns from one year to the next. The post is long but well worth reading. So is this due to global warming? Yes and no.

Winter brings visitors from the north, and attracts short-distance migrants into the Piedmont and coastal plain. Among the avian visitors are a host of sparrows, one of which is the fox sparrow.
Field guides do not quite convey how distinctive fox sparrows look in the field. Almost uniformly, they show the bright rufous upperparts and the crisp black chevrons on the breast. While these field marks are sufficient for identification, what really separates a fox sparrow from the most rufous of song sparrows is something that is harder to quantify. Fox sparrows stand out for their size and bulkiness even next to larger song and white-throated sparrows.
Fox Sparrows spend their summers in northern Canada and Alaska. The red, or eastern, form breeds in the boreal forest of eastern Canada and winters in the mid-Atlantic and southern United States. Other forms are distributed farther west. They can be spotted in the underbrush as the scratch through leaves for seeds and insects.
Since fox sparrows breed so far to the north, and only stay in this region for a few months, it is unusual to hear one sing at these latitudes. With all the warm weather lately, several observers in the DC area have reported hearing snatches of fox sparrow songs recently. A fox sparrow sings a clear, warbled song, similar to a purple finch or orchard oriole. It is something to listen for on your next walk in the woods.

Roger Tory Peterson is one of the premier figures in birding from the last century. In the early twentieth century, his field guides to birds aided the development of a class of amateur naturalists who practice their hobby with binoculars rather than shotguns. There must be few American birders today who are not familiar with Peterson's field guides and who have not been influenced by them. His Field Guide to Eastern Birds was the first that I used, and I still refer to it on occasion.
In addition to being an influential field guide illustrator, Peterson was a photographer and prolific writer. Even though he died ten years ago, he now has one more book to his name: All Things Reconsidered: My Birding Adventures. The book reprints essays from a regular column of the same name that Peterson wrote for Bird Watcher's Digest from 1984 until his death in 1996. The collection was prepared by Bill Thompson III, editor of Bird Watcher's Digest and blogger at Bill of the Birds.
The subtitle, "My Birding Adventures," applies best to a subset of essays. Peterson was an avid traveler, around the Americas and especially to Africa. These accounts display Peterson's skill as a story-teller as he recounts close encounters with wildlife, as well as mishaps on several trips. The travel narratives are beautifully illustrated, with some of Peterson's own photographs of the native avifauna.
Certain essays describe changes to the birding and conservation scenes in the years since Peterson first began his career. For example, the fortunes of raptors shifted remarkably during Peterson's lifetime, from persecution at migration sites in the early twentieth century, to protection and expansion mid-century, to near-extinction from DDT in the sixties, to a rebound in the century's waning decades. Other essays profile conservation figures and organizations that have come and gone, especially the persons who comprised the defunct Bronx County Bird Club.
As I read All Things Reconsidered, I was struck by Peterson's love of the natural world and his abilities as a writer. I had not read much of his work, so these essays were all new to me. If you have not read much of Peterson's work outside of his field guides, consider reading All Things Reconsidered.

I spent the afternoon birding in the National Arboretum. Because the year began in the middle of the week, this was my first real bird walk of the new year. I could not believe how many trees were already in full bloom. See, for example, the tree above, or the cherry tree below. I photographed these same trees blooming last year in early or mid March!
Despite some searching, I could not locate the pine warbler that spent much of December in the state tree grove. (Maybe it started migrating north.) The grove did sport two yellow-bellied sapsuckers, involved in a territorial dispute. Nearby meadows were full of birds, including the usual local sparrows - song, white-throated, and junco, as well as other common birds.
The river trail had a surprise sharp-shinned hawk. I also found several eastern phoebes and eastern bluebirds in the area of the gate from the Asian Gardens to the river trail. One phoebe was singing an odd song. It had the husky quality of a phoebe song, but with the pitch and rhythm of a wood-pewee song. So the result was something like "fee-a-bee, fee-bee." There were quite a lot of phoebes for early January. I think I saw at least four.
Before I left, I checked around the fruit tree area for finches. There were not many, but I did spot a few house finches. This tends to be a good spot for purple finches as well, but none were apparent this afternoon. Then again, a large flock of robins, such as were present today, makes it difficult to look for other species. The last species for the day was a pileated woodpecker, which I heard and then saw disappear into a hole. It's never too early to start a nest cavity, I guess.
Elsewhere in the park, two great horned owls were roosting together and were slightly different sizes, so I assume that they are a pair. As I stood and watched them for a few minutes, I was struck by how closely their wing feather pattern resembles tree bark. No wonder it is usually so difficult to find them!

Haloscan comments are back!
Comments from the last couple of weeks since the template change will not be visible, but all of the comments from the previous year should be accessible again. I think that overall Haloscan has a better commenting system. It does not have Blogger's clumsy word verification, and it offers the ability to manage all comments from a single page.
These are the ten species I hope to add to my life list during 2007. As with last year's list, I am confining myself to birds that are at least regular visitors to the east coast.
- Horned Lark
- Connecticut Warbler
- Virginia Rail
- Rough-legged Hawk
- Common Redpoll
- Greater White-fronted Goose
- Golden-winged Warbler
- Golden Eagle
- Upland Sandpiper
While I am at it, here is my 2007 wish list for DC. Some are life birds; others are birds I have only seen outside the District.
- American Pipit
- Horned Lark
- Pine Siskin
- Connecticut Warbler
- Little Blue Heron
- Golden-winged Warbler
- Wild Turkey
- Summer Tanager
- Yellow-throated Warbler
- Cattle Egret

For the past three years, I have participated in the Raritan Estuary Christmas Bird Count, along with my mother and sister, both of whom are birders. We have responsibility for a sector that runs along the Raritan River between the Route 18 and the Route 1 bridges. It includes parts of Johnson Park in Piscataway and Donaldson Park in Highland Park. While this sector does not offer many unusual species, the count is a fun way to close out the year. When we started out last Saturday, the skies were blanketed by a heavy cloak of clouds, depressing bird activity and making it difficult to see the few birds that were active. By mid-afternoon, the sky had largely cleared, but by then we were winding down the day's activities.
While the day was not good for hawks generally, it was excellent for peregrines. We had one in Johnson Park and two in Donaldson Park, the latter two sitting together on top of a radio tower. Common mergansers - and waterfowl overall - were down from last year, possibly due to warm weather, with the caveat discussed here. Hairy woodpecker and hermit thrush made the list this year; absent were last year's killdeer, brown creeper, and red-winged blackbird. Canada geese topped the avian biomass for the day, followed closely by herring gulls. Starlings made a good run, but could not keep up with their larger relatives. The biggest surprise was that robins were entirely absent from the two parks on count day; last year we counted 356!
One flock of Canada geese in Johnson Park contained some interesting geese. The first, on the surface, looks a bit like a greater white-fronted goose. It has the white strip of feathers at the base of a pink bill and orange legs, and the overall color patterns look right. However, a closer look reveals that this bird lacks the expected black speckling on the belly and has a light brown cheek patch. In addition, the size of the bird seems too large for a greater white-fronted goose. It is, in fact a hybrid, a mix of a Canada goose with either a greater white-fronted or domestic goose.
As I was studying that goose, I noticed two other birds in the same flock that seemed smaller than the rest - about two-thirds the size of other geese in the flock. They had blocky heads and proportionately small bills. After consulting several resources, I decided that these are cackling geese, probably the "Richardson's" subspecies. (There is more on cackling geese here.)
The table below shows the total species and numbers for our sector.
|Great Blue Heron||2|
|Great Black-backed Gull||175|
|Total Species (without hybrid)||39|
The 2005 results from our sector are posted here.
