By Anna Ferguson, The Brunswick News, Ga. Jul. 9--Perched in a towering thin tree on Jekyll Island, a colony of tall slender birds sits above the sand. It is an unusual site, causing passersby to stop and take a second look. What the spectators are seeing is more than a striking scene. It is proof of nature restoring itself. When wood storks began nesting on the Georgia coast about 50 years ago, the endangered species was seeking refuge. In the decades since the birds have been...

By Jeremy Manier and Tim De Chant, Chicago Tribune Jun. 27--When a falcon swoops from the sky to seize its fleeing prey, no one would mistake the sleek predator for a gaudy parrot. Yet the secret kinship of falcons and parrots is one of many surprises in a landmark genetic study of 169 bird species being published by Field Museum researchers. The lovely birds we see each day may never look quite the same again. One likely consequence of the study in Friday's edition of the journal...

Observing local birds' 'mob' behavior helps migrants avoid predators, say Queen's biologists Migrating songbirds take their survival cues from local winged residents when flying through unfamiliar territory, a new Queen's University-led study shows. It's a case of "When in Rome, do as the Romans do," says biologist Joseph Nocera, who conducted the research while working as an NSERC Postdoctoral Fellow at Queen's under the supervision of Biology professor Laurene Ratcliffe. Avoiding predators...

Some migratory songbirds figure out the best place to live by eavesdropping on the singing of others that successfully have had baby birds "“ a communication and behavioral trait so strong that researchers playing recorded songs induced them to nest in places they otherwise would have avoided. This suggests that songbirds have more complex communication abilities than had previously been understood, researchers say, and that these "social cues" can be as or more important than the...

Eurasian reed warblers captured during their spring migrations and released after being flown 1,000 kilometers to the east can correct their travel routes and head for their original destinations, researchers report online on January 31st in Current Biology, a publication of Cell Press. The new evidence suggests that the birds have true navigation, meaning that they can identify at least two coordinates that roughly correspond to geographic latitude and longitude. The findings challenge the...

BONN, Germany - Disoriented by erratic weather, birds are changing migration habits and routes to adjust to warmer winters, disappearing feeding grounds and shrinking wetlands, a migration expert says. Failure to adapt risks extinction. Birds face starvation when they arrive too early or too late to find their normal diet of insects, plankton or fish. In the north, some birds have stopped migrating altogether, leaving them at risk when the next cold winter strikes. "Species that adapted to...

Why do some birds fly thousands of miles back and forth between breeding and non-breeding areas every year whereas others never travel at all?  One textbook explanation suggests either eating fruit or living in non-forested environments were the precursors needed to evolve migratory behavior.  Not so, report a pair of ecologists from The University of Arizona in Tucson. The pressure to migrate comes from seasonal food scarcity. "It's not just whether you eat insects, fruit,...

By Rotenberg, James A ABSTRACT.- Established parks and nature reserves may be inadequate to preserve long-term biotic diversity, especially in tropical regions of Latin America where anthropogenic disturbance and land- conversion is an ongoing problem. Demand for economically productive land uses, such as cattle pastures or monoculture plantations, is one of the greatest threats to habitat and wildlife preservation. As a result, conservation biologists have turned to examining attributes of...

By Nita Bhalla NAIROBI -- The world's second largest shark, a bird found in the Garden of Eden and Central Asia's only true deer were among 11 new species given the title of "endangered" by countries around the world on Friday. Around 95 countries, members of the Convention on Migratory Species (CMS), agreed that several birds and mammals faced increasing threats to their survival and needed more protection. "The 11 species will join a listing of around 107 migratory animals which are...

The Pine Warbler (Dendroica pinus), is a small songbird of the New World warbler family. Their breeding habitats are open pine woods in eastern North America. These birds are permanent residents in southern Florida. Some of them, however, migrate to northeastern Mexico and islands in the Caribbean. The first record for South America was a vagrant wintering female seen at Vista Nieve, Colombia, on 20 November 2002. This bird was foraging as part of a mixed-species feeding flock that also...
