Latest Bird migration Stories
Worldwide pandemics of influenza caused widespread death and illness in 1918, 1957, 1968 and 2009. A new study examining weather patterns around the time of these pandemics finds that each of them was preceded by La Niña conditions in the equatorial Pacific. The study's authors--Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health—note that the La Niña pattern is known to alter the migratory patterns of birds,...
ST. LOUIS, Jan. 3, 2012 /PRNewswire/ -- The Northeastern portion of the United States is leading the nation in outbound migration- a designation held by the Great Lakes region for the past several years. Washington, D.C., continues to be the nation's most popular destination. The findings are among the results of United Van Lines' 35th annual "migration" study, which tracks where its customers move from and the most popular destinations during the course of the year. The findings...
Predicting the risk of extinction is a complicated task, especially for species that migrate between breeding and wintering sites. Researchers at the University of Georgia and Tulane University have developed a mathematical model that may make such predictions more accurate. Their work appears in the early online edition of the Royal Society journal Biology Letters. "The concern is that for a lot of species, we don't know very much about their wintering grounds," said Richard Hall,...
More than half of eastern U.S. tree species examined in a massive new Duke University-led study aren't adapting to climate change as quickly or consistently as predicted. "Many models have suggested that trees will migrate rapidly to higher latitudes and elevations in response to warming temperatures, but evidence for a consistent, climate-driven northward migration is essentially absent in this large analysis," says James S. Clark, H.L. Blomquist Professor of Environment at Duke's...
ATLANTA, Oct. 20, 2011 /PRNewswire/ -- A group of 10 young whooping cranes has taken to the air on an annual migration to help conserve the species, and Southern Company is standing behind them. As part of its commitment to environmental stewardship, Southern Company, in partnership with the National Fish and Wildlife Foundation, has sponsored Operation Migration through the Power of Flight conservation program since 2008. Operation Migration's mission is to promote the conservation of...
Mimecast’s new Exchange migration guidelines now provide explanations on how to prepare the existing infrastructure, what safeguards to put in place and how to perform the Exchange migration. The company has just introduced six-month package of Migration Services aimed at organisations upgrading to Microsoft Exchange 2010 or Office 365, helping to prevent email downtime and data loss during the migration process. (PRWEB) October 11, 2011 An Exchange migration can produce a number...
In an intriguing original look at the history of the first Americans, a new study finds evidence that the north-south orientation of the American continents slowed the spread of populations and technology, compared to the east-west axis of Eurasia. The research, published in the American Journal of Physical Anthropology, is part of a special section which explores who the first Americans were and how they were able to settle in the last great unexplored habitat. The research, by Sohini...
Researchers at Brown University and Stanford University have pieced together ancient human migration in North and South America. Writing in the American Journal of Physical Anthropology, the authors find that technology spread more slowly in the Americas than in Eurasia. Population groups in the Americas have less frequent exchanges than groups that fanned out over Europe and Asia. How modern-day humans dispersed on the planet and the pace of civilization-changing technologies that...
HARRISBURG, Pa., July 26, 2011 /PRNewswire-USNewswire/ -- Early Canada goose and dove hunters will be able to take to the fields of Penn's Woods on Sept. 1, as part of Pennsylvania's 2011-12 migratory bird seasons announced today by Pennsylvania Game Commission Executive Director Carl G. Roe. Dove hunters will have the opportunity to participate in a triple-split season, which will see some shifts due to the way the calendar falls this year. During the first season (Sept. 1 - Oct. 1),...
Until recently, migration patterns, such as those adopted by birds all across the Amazonian rainforest, have not been thought to play an important role in the spreading of beneficial genes through a population.Researchers have now, for the first time, been able to predict the chance of a gene spreading when given any migration pattern, potentially providing an insight into the migration patterns of animals throughout history.Even more impressively, the concepts from these predictions can be...

The Green Pygmy Goose (Nettapus pulchellus) is a small perching duck found in southern New Guinea and northern Australia. It is largely resident, apart from dispersion during the wet season. The habitat is well vegetated lowland lagoons and other permanent fresh waters.
The Canada goose (Branta canadensis), also called the Canadian Goose in North America, belongs to the Branta genus of geese. This genus contains species with largely black plumage, distinguishing them from the grey Anser species. The species name, canadensis, is a New Latin word meaning "of Canada". The black head and neck with white "chinstrap" distinguish this goose from all except the Barnacle goose, but the latter has a black breast and grey, rather than brownish, body plumage. There...
The Red Knot (Calidris canutus), or Knot in Europe, is a species of bird found in the tundra and Arctic mountains in the far north of Canada, Europe and Russia. North American birds migrate to coastal Europe and South America, while European birds migrate to Africa, Papua New Guinea, Australia and New Zealand. This species has an extensive range and a large population of about 1.1 million individuals. There are six subspecies. The adult is 9 to 10.25 inches in length with an 18.5 to 20.8...
The Whooping Crane (Grus americana) is a very large crane and the tallest North American bird. Adult birds are white with a red crown and a long dark pointed bill. They have long dark legs which trail behind in flight and a long neck that is kept straight in flight. Black wing tips can be seen in flight. Immature birds are pale brown. Their breeding habitat is muskeg; the only known nesting location is Wood Buffalo National Park in Canada and its surrounding area. They nest on the...
