Tropical birds have slow pace of life compared to northern species, study finds
05-22-2007 · EurekAlert!In the steamy tropics, even the birds find the pace of life a bit more relaxed, research shows. Tropical birds expend less energy at rest than do birds living in more northern climates, according to a study published online this week in the Proceedings of the National Academy of Sciences.

- Cities change the songs of birds
12-04-2006 · EurekAlert!
By studying the songs of a bird species that has succeeded in adapting to urban life, researchers have gained insight into the kinds of environmental pressures that influence where particular songbirds thrive, and the specific attributes of city birds that allow them to adjust to noisy urban environments. The findings, reported by Hans Slabbekoorn and Ardie den Boer-Visser of Leiden University, appear in the December 5 issue of Current Biology.

- Ecologists discover city is 'uber-forest' for big owls
10-16-2007 · EurekAlert!
Charlotte has a spooky secret: the North Carolina city is home to a robust population of very large barred owls -- a species long-believed by ornithologists to require old growth forest for survival. According to ecologists doing the most extensive field study ever done on the species, the owls see urban life as an upgrade on the old woods, and Charlotteans are not at all creeped out by the big birds that share their yards.

- Alpine bird numbers on the slide due to high-altitude ski runs
01-16-2007 · EurekAlert!
High-altitude ski runs are seriously affecting Alpine birds, ecologists have found for the first time. Writing in the January issue of the Journal of Applied Ecology, Italian ecologists warn that ski pistes above the tree line result in fewer species and lower numbers of birds compared with natural grassland at similar altitudes. Ski developers should use new, environmentally-friendly techniques when constructing pistes in future, they say.

- Uncertainty of rainfall breeds cooperation in birds, study finds
08-16-2007 · EurekAlert!
For the first time, Cornell researchers have linked a specific aspect of the environment to the evolution of cooperative breeding in numerous bird species: unpredictable rainfall. Their findings on African starlings appear in the Aug. 21 issue of Current Biology.

- Slow but sure -- Burned forest lands regenerate naturally
04-04-2007 · EurekAlert!
A new study of forest lands that burned in the 1990s in northern California and southwestern Oregon has concluded there is a "fair to excellent" chance that an adequate level of conifers will regenerate naturally, in sites that had no manual planting or other forest management. Whether lands should be planted and weed competition controlled is more a question of short-term timber production, tree species control and forest management goals than the regeneration of the forest, the study indicated.

- Information on bird flu cases poorly recorded, scientists say
11-01-2006 · EurekAlert!
Critical information about cases of infection of wild birds by H5N1 highly pathogenic avian influenza is being recorded inaccurately or not recorded at all, according to scientists writing in BioScience. Species and sex of the bird as well as exact time and location of trapping or collection are among the data that have been improperly reported, compromising attempts to study the disease.

- Museum-fueled global study shows you can't judge biodiversity by its bird
11-01-2006 · EurekAlert!
The canary in the coal mine, the supposed harbinger of threat for all those around it, isn't as true as it seemed for biodiversity conservation, according to a sweeping study in which a Michigan State University ornithologist participated.A global group of scientists including MSU's Pamela Rasmussen, has done the most detailed study yet of how rare and threatened species of birds, mammals and amphibians are distributed across the globe.

- Some forest birds can survive in agricultural countryside with limited habitat conservation
05-24-2007 · EurekAlert!
Some tropical forest birds can survive alongside humans if given a helping hand, according to a recent study by Cagan H. Sekercioglu, senior scientist at the Stanford University Center for Conservation Biology.The results, published in the April 2007 issue of the journal Conservation Biology, could influence the way countries approach endangered species protection in agricultural areas.

- Ancient fish bones reveal impacts of global warming beneath the sea
12-12-2007 · EurekAlert!
Through the study of archaeological material, tax accounts, church registers and account books of monasteries, an international group of fisheries ecologists and fisheries/maritime historians have drawn a picture of marine life in the northern European seas as it looked in the past. Their findings are presented in a special issue of Fisheries Research "History of Marine Animal Populations and their Exploitation in Northern Europe."
