Birds and birding news

• The Nēnē family in the photo at the top of this post are the first breeding record on Oahu (pdf) since the 18th century. The Nēnē (also known as Hawaiian Goose) is an endangered species, and about 2,000 are alive in the wild. See this article for more images of the geese.
• Atlantic Puffin chicks are suffering from a lack of herring and hake in the Gulf of Maine. When those fish are not available, parents bring back butterfish, which are too large for the chicks to swallow. The decline in herring and hake seems to be linked to warmer ocean temperatures.
• Some readers may remember a report from a few weeks ago of trees bearing Black-crowned Night Heron nests being trimmed of the branches supporting their nests. Here is an update: none of the birds were killed (early reports erroneously mentioned birds being fed into a wood chipper), but several were injured and are being treated. It looks like the tree trimmer will be held accountable, but so far there is no indication the post office will be.
• Flickr recently changed the code it gives users to embed photos on other websites, and this affects how photos appear in eBird checklists.
• California Brown Pelicans are having a very bad breeding season so far.
• The June challenge for eBird calls for submitting complete checklists with breeding data.
• A new Guatemalan reserve will protect Highland Guan, Great Curassow, and Keel-billed Motmot, among other wildlife.
• Scientists split the Wakatobi Flowerpecker (found in Wakatobi islands in Indonesia) from the similar Grey-sided Flowerpecker.
• Two Black Vultures have been roosting around K Street in Washington, DC.
• The trail adjacent to the Edison Boat Basin will be renamed Riverside Park. The site is one of the better spots in Middlesex County (NJ) for finding unusual gulls, other waterbirds, and sometimes raptors.
• For readers in the DC area: The National Museum of Natural History is hosting an exhibition on bird extinction this summer, with an exhibition opening on June 24 that will feature Joel Greenberg, author of A Feathered River Across the Sky.

Environment and biodiversity

• This week, the EPA finally announced regulations limiting the amount of carbon dioxide that can be released by power plants. It was probably about the best that Obama could accomplish in the current political atmosphere, even though regulating carbon emissions from power plants has majority support in polls.
• The decline of Monarchs is most likely cause by the increasing agricultural use of herbicides and the elimination of milkweed patches for breeding and foraging. Milkweed patches have declined because more land is being planted with corn.
• This year's grasshopper emergence around Albuquerque is at a 20-year peak, and the grasshoppers are so abundant that they have been showing up on weather radar, much like birds do during migration. This spring's massive swarms were likely triggered by an exceptionally dry winter that did not destroy enough grasshopper eggs.
• Bees are able to detect polarization patterns, which help them identify flowers for foraging. (Unfortunately the article is illustrated with a honeybee instead of the species used in the study.)
• Scientists are trying to figure out why the bioluminescent dinoflagellates in Mosquito Bay (Puerto Rico) have suddenly stopped glowing. 
• An epidemic wasting disease has been killing many of the purple ochre sea stars along the Oregon coast. 
• Climate changes is bringing warmer temperatures fastest in the northeastern and southwestern U.S. Overall, average summer temperatures have warmed by 0.4°F per decade in the U.S.
• The massive Funny River fire in Alaska was enabled by a beetle infestation and climate change.
• El Niño is now 70% likely to occur this summer and will probably do significant harm to coral reefs.
• Brazil has saved a significant amount of greenhouse gas missions by slowing deforestation.
• The ocelot population in the U.S. numbers about 50, down from 100 a decade ago.
• NRDC has a petition to end the excesses of USDA Wildlife Services.
• Wolf OR-7, known for his travels through California, has been confirmed breeding in Oregon.
