New host species for avian influenza identified
In a new study published online in the open-access journal PLoS Pathogens, Dr. Vincent J. Munster, of Erasmus Medical Center, Rotterdam, and colleagues identify new host species for avian influenza A virus (H5N1) and provide important information on the distinctions between the ecology and epidemiology of various global strains of the virus. view more (2007-05-11)
West Nile Virus infections detected in Britain
A paper in the Journal of General Virology reveals that evidence of West Nile virus infections has been found in birds in Britain, according to a team of scientists led by the Centre for Ecology and Hydrology (CEH) at Oxford. There are no known cases of human infection and no disease reported in birds. Dr Ernie Gould and colleagues believe that... view more... (2003-07-18)
Northern birds are fatter!
"The further birds migrate north for the summer, the faster they put on weight", says Dr Williams (Simon Fraser University, Canada) who has been tracking migrating birds for several years. view more (2006-04-04)
Study finds migratory birds not picky about their rest stops
If a lush, protected forest with a winding stream is considered luxury accommodation for a migratory bird, a Purdue University study shows that those birds would be just as happy with the equivalent of a cheap roadside motel. view more (2009-08-13)
Urbanization favors sedentary males
Urbanization changes landscapes and local environments, which can alter the life histories and traits of the creatures living in and around these areas. view more (2007-05-02)
Overbearing colored light may reveal a second mechanism by which birds interpret magnetic signals
Magnetic orientation is critical to the migratory success of many bird species. By studying the influence of light on the ability of migratory birds to orient to magnetic signals, researchers have found clues to suggest that birds' orientation abilities may be more complex than previously thought. view more (2005-08-23)
Tropical winter habitat drives natal dispersal of young migratory birds
A new study by scientists at the Migratory Bird Center at the Smithsonian's National Zoo shows that the factors determining where birds settle and nest in the first breeding season depends on the habitat they used during their first winter in the tropics. view more (2008-02-19)
Displaced songbirds navigate in the high Arctic
By experimentally relocating migratory white-crowned sparrows (Zonotrichia leucophrys gambelii) from their breeding area in the Canadian Northwest Territories to regions at and around the magnetic North Pole, researchers have gained new insight into how birds navigate in the high Arctic. view more (2005-09-07)
Why do birds migrate?
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? view more (2007-03-02)
West Nile virus antibodies sought in birds in England
Scientists at the Centre for Ecology and Hydrology at Oxford are investigating live birds to see whether or not West Nile virus is present and being actively transmitted between resident and migratory birds. No infectious virus has as yet been detected. The birds sampled were healthy, implying that if present the virus is not virulent and may... view more... (2002-10-31)
Seeing magnetic fields
It has long been known that migratory birds can make use of the earth's magnetic fields to navigate. Birds read the angle that magnetic fields create on the ground and thereby determine how far north or south they are of the magnetic equator and the magnetic pole. But how do they do this? Is there some unknown "magnetic sense"? It seems... view more... (2004-02-23)
We're off then: the evolution of bat migration
Not just birds, but also a few species of bats face a long journey every year. Researchers at Princeton University in the U.S. and at the Max Planck Institute for Ornithology in Radolfzell, Germany studied the migratory behaviour of the largest extant family of bats, the so-called "Vespertilionidae" with the help of mathematical models. view more (2009-11-24)
Migrating songbirds learn survival tips on the fly
Migrating songbirds take their survival cues from local winged residents when flying through unfamiliar territory, a new Queen's University-led study shows. view more (2008-06-26)
Low-pathogenic forms of bird flu do cause illness among birds
Migratory swans carrying a mild form of avian influenza depart from The Netherlands more than a month after their healthy counterparts do. view more (2007-01-31)
Light guides flight of migratory birds
Songbirds use multiple sources of directional cues to guide their seasonal migrations, including the Sun, star patterns, the earth's magnetic field, and sky polarized light patterns. view more (2006-08-11)
Scientists determine geese involved in Hudson River plane crash were migratory
Scientists at the Smithsonian Institution examined the feather remains from the Jan. 15 US Airways Flight 1549 bird strike to determine not only the species, but also that the Canada geese involved were from a migratory, rather than resident, population. view more (2009-06-09)
Birds carry bacteria across the hemispheres: Migratory birds transmit borreliosis
Migrating birds transmit different forms of the Borrelia bacterium or Borrelia spirochetes to every corner of the globe. Birds are especially prone to Borrelia infected ticks during their autumn and spring migrations. The bacteria may also persist for several months in the birds and it may then be reactivated in response to migration. Borrelia... view more... (2005-05-20)
Mangrove-dependent animals globally threatened
More than 40 percent of a sample of amphibians, reptiles, mammals, and birds that are restricted to mangrove ecosystems are globally threatened with extinction, according to an assessment published in the July/August issue of BioScience. view more (2009-07-01)
A giant wind-powered generator
The new TWT-1650 wind-powered generator presented in Pamplona has 36-metre vanes which, in a circular movement, sweep an area greater than that of a football pitch and which can withstand extremes of weather, including winds of up to 110 kilometres an hour. This device, made by Grupo Mtorres in collaboration with the Institute for the... view more... (2003-10-14)
Beavers: Dam good for songbirds
The songbird has a friend in the beaver. According to a study by the Wildlife Conservation Society (WCS), the busy beaver's signature dams provide critical habitat for a variety of migratory songbirds, particularly in the semi-arid interior of the West. view more (2008-10-09)
