Even tiny patches of woods in urban areas seem to provide adequate food and protection for some species of migrating birds as they fly between wintering and breeding grounds, new research has found. The results are important because, with the expansion of cities worldwide, migrating landbirds increasingly must pass through vast urban areas which offer very little of the forest habitats on which many species rely. "The good news is that the birds in our study seemed to be finding enough food...

The results of genetic studies on migratory birds substantiate the theory that in the case of a continued global warming, and within only a few generations, migratory birds will - subject to strong selection and microevolution - at first begin to fly shorter distances and at a later stage, stop migrating, and will thus become so-called "residents". In a selection experiment with blackcaps from southwest Germany, Francisco Pulido and Peter Berthold at the Max Planck Institute for Ornithology...

Heavy migratory birds take shorter breaks and reach their breeding grounds faster Small migratory birds, like the garden warbler, must make stopovers on their journeys to their breeding grounds. When they have crossed extensive ecological barriers, such as deserts or oceans, they must land to replenish their fat reserves. A researcher from the Max Planck Institute for Ornithology in Seewiesen and a team of Italian colleagues measured the duration of the stopovers made by garden warblers on an...

Researchers for the Wildlife Conservation Society have discovered for the first time the breeding area of the large-billed reed warbler"”dubbed in 2007 as "the world's least known bird species""”in the remote and rugged Wakhan Corridor of the Pamir Mountains of north-eastern Afghanistan. Using a combination of astute field observations, museum specimens, DNA sequencing, and the first known audio recording of the species, researchers verified the discovery by capturing and...

Birds' alarm calls serve both to alert other birds to danger and to warn off predators. And some birds can pull a ventriloquist's trick, singing from the side of their mouths, according to a UC Davis study. Many animals respond vocally when they detect predators, but it's not clear to whom they are signaling, said Jessica Yorzinski, a graduate student in animal behavior at UC Davis who conducted the study with Gail Patricelli, professor of evolution and ecology. They might be warning others...

Ecologists have at last worked out a way of using recordings of birdsong to accurately measure the size of bird populations. This is the first time sound recordings from a microphone array have been translated into accurate estimates of bird species' populations. Because the new technique, reported in the British Ecological Society's Journal of Applied Ecology, will also work with whale song, it could lead to a major advance in our ability to monitor whale and dolphin numbers. Developed by...

Biologists for the first time have documented a second breeding season during the annual cycle of five songbird species that spend summers in temperate North America and winters in tropical Central and South America. It was known that these species, which migrate at night when there are fewer predators and the stars can guide their journey, breed during their stay in temperate regions of the United States and Canada. But it turns out that they squeeze in a second breeding season during a...
