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.

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…

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…

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…

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…

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,…

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…

Boreal or Tengmalm's Owl, Aegolius funereus.
Boreal Owls are circumpolar, occupying subalpine and northern, or boreal,
forests around the globe. These seasonally monogamous birds nest in small
cavities; woodpecker holes, other natural tree cavities, or man-made nest boxes.
These small owls occasionally irrupt from their northerly homes in search of food.

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…

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.

A record number of bird species are now listed as threatened with extinction, a global assessment has revealed. The IUCN Red List evaluation considered 1,227, or 12%, of all known bird species to be at risk, with 192 species described as Critically Endangered. The main threats affecting bird numbers continued to be agriculture, logging and invasive species, the…

"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.

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…
