'Magnet Molecule' May Guide Bird Migration

Feathered friends confused by the light, scientists believe

(NEWSER) - The city that never sleeps will be a little less bright through Nov. 1, as buildings hit the lights to protect migrating birds. An estimated 90,000 birds die each year by slamming into buildings in NYC alone; turning lights off can reduce that number by 83%, according to one study. The Empire State and Chrysler buildings have jumped aboard the "lights out" program, run by NYC Audubon, and will turn off their lights from midnight to dawn during the autumn migration, notes the BBC .

Free lunch rocks birds' futures

(NEWSER) - Darwin never made allowances for birdfeeders, but modern-day scientists have discovered that giving feathered friends a helping hand can have profound evolutionary consequences. Filling up birdfeeders with seeds and suet can convince birds to hang around for the free lunch, rather than take off of their migratory routes, researchers have found. European blackcaps who snack at birdfeeders in England instead of migrating to winter grounds in Spain to feast on fruit are on the verge of becoming their own stay-at-home species. More»

(NEWSER) - Researchers have tracked the migratory paths of songbirds for the first time, using small data-gathering “backpacks,” the Washington Post reports. The avian wanderers, who are so small they cannot be tagged with transmitters, move about 3 times as a fast as previously thought. The recovered data shows that birds traveling between the US and Brazil can make up to 311 miles in a day. They're usually faster heading south, possibly in a race to get the best breeding spots.

DNA research reveals new information about bird relations

(NEWSER) - A five-year study of bird DNA is turning the world of ornithology on its head. The study revealed such drastic new information about the evolution of birds that dozens will need new scientific names, the Chicago Sun-Times reports. Notable finds: Falcons are not related to hawks or eagles; hummingbirds—colorful daytime creatures—evolved from the drab nocturnal nightjar; and parrots are more closely related to songbirds than thought.
