Birds in Science Low-quality females prefer low-quality males, at least in the avian world. This is according to research published in the Royal Society journal Proceedings B, testing female zebra finches' taste in males. As adults, the low-quality females showed a preference for the songs of males of the same quality, and for the male birds themselves. Evolutionary biologists previously thought that females would always opt for the best male available. A…

Birds in Science By genetically modifying the brains of songbirds for the first time, scientists may have a devised useful new tool for studying neurological growth and healing in humans. "Songbirds have become a classic tool for studying vocal learning and neuron replacement. This will bring those two topics into the molecular age," said neuroscientist Fernando Nottebohm of Rockefeller University, author of a study published recently in the Proceedings of the…

Birds in Science News Maori legends told of a giant predatory bird called the Te Hokioi, whose wingspan approached the length of a full-grown man and whose prey included human beings. Now Kiwi scientists are adding to the legend by claiming that a skeleton found in the 1870s shares some of the legendary bird's traits. "We don't think it…

Birds and Technology Rather than searching for weird weather or enemy missiles, some satellites are helping researchers to track -- and predict -- the spread of deadly diseases. With the pandemic spread of H1N1 swine flu and the continued advance of the H5N1 avian flu, scientists are anxious to better predict the spread of infectious diseases and are looking for new tools wherever they…

Birds in Science Brainy male birds are more sexually attractive to female birds, scientists have discovered. Researchers gave male bowerbirds a set of cognitive tests to evaluate their problem solving ability. Bowerbirds that performed well in the tests also mated with the most…

Birds in Science For centuries, scientists have puzzled over why the toucan's bill is so remarkably large -- but now one team thinks it might have an answer. The researchers say that the toucan uses its enormous beak to stay cool. They used infrared cameras to show the bird dumping heat from its body into its bill, helping it to regulate its body temperature. The toucan has the largest bill of any bird,…

Birds in Science Bird deaths around the Baltic Sea and possibly elsewhere in the world may be caused by a shortage of the vitamin thiamine, researchers say. Wild birds of varied species along the Baltic coasts have been dying of hard-to-explain paralysis since…

Birds in Science Catching adult eagles for research purposes is no easy task, but a Purdue University researcher has found a way around the problem, and, in the process, gathered even more information about the birds without ever laying a hand on one. "Many birds are small, easy to catch and abundant," said Andrew DeWoody, associate professor of forestry and natural…

Birds in Science One of the fifteen Frisian 'transmitter godwits', which was still in Friesland on one week ago on Saturday, arrived in Senegal in West Africa on Tuesday morning. The bird, nicknamed Heidenskip, appears to have flown from Friesland via Spain and over the Sahara in one go. The distance, over…

Boreal Owls are circumpolar, occupying subalpine and northern, or boreal, forests around the globe.

Birds in Science Unpredictable weather seems to stimulate chatter among birds -- as well as humans -- according to researchers. A team of US scientists has found that Northern Mockingbirds living in variable climates sing more elaborate songs. Complex tunes, sung by males to impress females, are likely to signal the birds' intelligence. Carlos Botero, a researcher from the National Evolutionary Synthesis Center in North Carolina, led the study. Dr…

The shooting of two rare California condors, like this one, set phones ringing at the offices of environmental groups. Image: [larger view]. Birds in Science Northern Mockingbirds tend to sing fancier tunes with changing climate, say researchers. The research team from the National Evolutionary Synthesis Centre (NESCent), the Cornell Lab of Ornithology, and McGill University showed that species in more variable climes also sing complex tunes. "Survival and reproduction become more…

Birds in Science and Technology "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…

Birds in Science and Technology 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…
