 | A novel genetic study has revealed why chickens have yellow legs, demonstrating that though Charles Darwin was right about many things, his view on the origins of the chicken was not entirely correct. ...> Full Article |
Did modern birds originate around the time of the dinosaurs' demise, or have they been around far longer?

 | Whereas most birds are sole proprietors of their nests, some tropical species "time share" together - a discovery that helps clear up a 150-year-old evolutionary mystery. ...> Full Article |
 | Brood parasitic birds, which place their eggs in a nest for other birds to care for, can act like an inherited disease, affecting future generations of the birds they victimize. ...> Full Article |

 | Researchers have found that New Caledonian crows--which are known to make complex food-getting tools in the wild--can also spontaneously use one tool on another to get a snack. ...> Full Article |
 | An Australian bird has been found to produce smaller, less nourishing eggs when it breeds in the presence of other 'helper' birds that provide child-care assistance. This unique adaptation enables the birds to live longer and breed more often than females without helpers. The research, led by a University of Cambridge academic, was published in Science. ...> Full Article |
 | Delaying having kids to help raise the offspring of others seems like a bad choice if you want to reproduce, but many African starlings have adopted this strategy to deal with the unpredictable climate of their savanna habitats, according to a new study by University of California, Berkeley, and Cornell University biologists. It appears in the Aug. 21 issue of the journal Current Biology. ...> Full Article |
.jpg) | A researcher at the University of Sheffield has discovered that the reason birds learn to fly so easily is because latent memories may have been left behind by their ancestors. ...> Full Article |
 | A gene mutation that appears to be responsible for changing relatively mild forms of the West Nile virus into a highly virulent and deadly disease in American crows has been identified by a team of scientists led by a researcher at the University of California, Davis. ...> Full Article |
 | Assessing the projected impacts of invasive species is a leading issue for scientists today. A major question for ecologists is determining which characteristics will predispose a species to be a good or bad colonizer when introduced into an ecosystem. New research from assistant professor at the UGA Odum School of Ecology John Drake adds another piece to the invasive species puzzle. ...> Full Article |
 | The eggs of the penduline tit Remiz pendulinus are frequently abandoned as both parents go in search of new sexual conquests, a study published in the Journal of Evolutionary Biology has found. ...> Full Article |
 | Researchers at the School of Biosciences at the University of Birmingham have discovered that cormorants' underwater vision is no better than that of humans. They have found that these birds flush out prey by disturbing it, rather than pursuing it at speed. ...> Full Article |
A strain of chickens that are naturally blind produce more eggs than their sighted counterparts, a U of G animal scientist has found.

Brightly coloured birds are among the species most adversely affected by the high levels of radiation around the Chernobyl nuclear plant, ecologists have discovered. The findings – published online in the British Ecological Society's Journal of Applied Ecology – help explain why some species are harder hit by ionising radiation than others.

 | While humans stray from their mates for any number of reasons, superb starling females appear to stray for the sake of their chicks, according to recent Cornell research published in the Proceedings of the Royal Society of London B. ...> Full Article |
 | Flowers evolve in a predictable fashion to match the mouthparts of pollinating birds and insects, rather than engaging in a gradual "arms race" between flower and pollinator, according to a new study by researchers at the University of California, Davis and the University of California, Santa Barbara. An article describing the study is published in the June 7 issue of the journal Nature. ...> Full Article |
 | Prehistoric Polynesians, not European voyagers, may have brought chickens to the Americas, according to new research from The University of Auckland's Department of Anthropology which will be published in the prestigious journal, Proceedings of the National Academy of Sciences (PNAS). ...> Full Article |
In the steamy tropics, even the birds find the pace of life a bit more relaxed, research shows.

 | Your bird field guide may be out of date now that University of Florida scientists discovered a new genus of frogmouth bird on a South Pacific island. ...> Full Article |
 | Doubt is cast on one of the biggest assumptions in behavioural ecology. ...> Full Article |
 | One does not expect to discover a bird species new to science while wandering around the continental United States. Nor does one expect that such a species would provide much insight into how coevolutionary arms races promote speciation. On both fronts a paper to appear in The American Naturalist proves otherwise. ...> Full Article |
