"In the past, people thought birds were stupid," laments the aptly named scientist Christopher Bird. But in fact, some of our feathered friends are far cleverer than we might think. And one group in particular -- the corvids -- has astonished scientists with extraordinary feats of memory, an ability to employ complex social reasoning…

Zebra finches, which normally learn their complex courtship songs from their fathers, spontaneously developed the same songs all on their own after only a few generations. "We found that in this case, the culture was pretty much encoded in the genome," said Partha Mitra of Cold Spring Harbor Laboratory in New York, co-author of the…

Here's a link to the US Air Force Avian Hazard Advisory System, a system that processes NOAA weather data in real time and uses it to provide bird-aircraft strike risk advisories. The website also shows the processed image loop of bird density data (with most of the weather removed). There also is an image gallery for you to look at. In these images, the yellows indicate lower activity…

Climate change will force bone-weary birds migrating to Europe from Africa to log extra mileage, with possibly devastating consequences, according to a study released recently. The annual voyage of some species, which fly north in search of food and suitable climes, could increase by as much as 400km, the…

The American Federation of Aviculture Inc.

"H.R. 669 is an 'anti-animal bill'. There is no amendment that can fix this bill," states the action alert. H.R. 669 is a bill that…

Count your chickens after they hatch, and they may do a little arithmetic themselves.

Researchers have discovered the first direct evidence that exposure to stress in young birds affects the way they react to stress when adult. Exposure to stressful events soon after birth has significant effects on a range of physiological and behavioral responses later in life. Previous work in mammals has been unable to work out whether this is due to raised stress hormone levels produced by…

This is a link to a fascinating slide show that documents 9 links in the dinosaur-to-bird transition -- plenty of strong evidence that birds evolved from dinosaurs! GrrlScientist comment: "link" number four is very dubious, though, and I am surprised they even used it in their story.

The Greater Sage-Grouse, a species whose population has declined 93% from historic numbers and that is on the U.S. WatchList of birds of highest conservation concern, is facing a severe decline in the amount of suitable breeding habitat due to energy development. Oil and gas drilling in the region have been booming, driving the birds out of many breeding areas, or leks. In addition, wind farm…

One of the most contentious issues among scientists who study the evolution of birds is identifying precisely when the modern birds (Neornithes) first appeared. This is due to conflicts between the fossil record and molecular dating methodologies. For example, fossils support a Tertiary radiation whereas molecular dating methodologies…

European Bee-eater pair, Merops apiaster.
She's still hungry, but not yet willing to mate. So the male bee-eater takes wing
to find more food. When he returns, "the female nearly always accepts the
offering, quickly eating," reports British ornithologist C. Hilary Fry. If his
courtship is successful, he'll continue to bring her prey through the
egg-laying period. Both parents deliver meals to their chicks.
