Studies of migratory birds need to embrace a versatile mix of data - including geolocator technology, stable-isotope analysis , mark-recapture (banding) data along with citizen science data Animals move around the globe in billions, sometimes - like the snow bunting - one of the iconic Arctic-breeding species, covering huge distances and enduring the most extreme frigid weather conditions. In this conspicuously white sparrow-sized bird, animal migration epitomizes a stunning success of...

In a case of life imitating art, avian scents given off by male songbirds have the females (and males) flocking in. A Michigan State University researcher revealed the process of how males draw attention to themselves through chemical communication in the current issue of Behavioral Ecology. Scents are used in all organisms for many purposes, such as finding, attracting and evaluating mates. But this is the first study of its kind that demonstrates that it is happening among songbirds, said...

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...

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...

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...

The Wildlife Conservation Society says a monitoring system it uses to measure stream habitat has been adopted by a U.S. agency working to restore waterways. The conservation group said the technique, used in a study to rapidly measure stream habitat, has been adopted by the U.S. Department of Agriculture's Natural Resource Conservation Service to assess streams across the United States. Society officials said their study, which looked at riparian areas in semi-arid eastern Oregon, examined...

The Rufous-capped Warbler (Basileuterus rufifrons), is a New World warbler native from Mexico south to much of Central America, rarely occurring as far north as southeastern Arizona and south Texas. While Rufous-capped Warblers are generally birds of tropical shrubby highlands, North American sightings tend to be in oak woodland canyon bottoms, near running water, while the birds stay low in dense vegetation. Rufous-capped Warblers generally reach a length of about 5 inches in length. They...
