Researchers reconstruct the evolution of bat migration with the aid of a mathematical model 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 behavior of the largest extant family of bats, the so-called "Vespertilionidae" with the help of mathematical models. They discovered that the migration over short as well as long...

Biologists for the first time have documented a second breeding season during the annual cycle of five songbird species that spend summers in temperate North America and winters in tropical Central and South America. It was known that these species, which migrate at night when there are fewer predators and the stars can guide their journey, breed during their stay in temperate regions of the United States and Canada. But it turns out that they squeeze in a second breeding season during a...

Satellite tracking has allowed a research team to uncover the mysteries of the migration of Eleanora's falcon for the first time. In total, the bird flies more than 9,500 kilometers across the African continent from the Balearic and Columbretes Islands before reaching the island of Madagascar. Some of the previously-obscure secrets now revealed by the scientists show that these falcons migrate by both day and night, and cross supposed ecological barriers such as the Sahara Desert. Until...

A high-speed chase across the Panama Canal in a Boston Whaler may sound like the beginning of another James Bond film"”but the protagonist of this story brandishes a butterfly net and studies the effects of climate change on insect migrations at the Smithsonian Tropical Research Institute. "Our long-term study shows that El Niño, a global climate pattern, drives Sulfur butterfly migrations," said Robert Srygley, former Smithsonian post doctoral fellow who is now a...

The U.S. Geological Survey says global warming has resulted in some arctic-nesting geese electing to spend the winter in Alaska instead of Mexico. USGS scientists said they've discovered the winter distribution of Pacific brant -- a small, dark sea goose -- shifted northward from Mexico to sub-Arctic areas as Alaska's climate warmed in the last four decades. The USGS-led survey found until recently, about 90 percent of Pacific brant wintered in Mexico. Now as many as 30 percent are opting to...

 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.John Dunning, an associate professor of forestry and natural resources, found that migrating birds are just as likely to stop in small woodlots in the middle of an agricultural field for the night as long as there is adequate protection and food. Dunning said the...

A U.S. study suggests migrating birds will stop in any environment where there is adequate food and protection, and not just in large forested areas. Purdue University Associate Professor John Dunning and graduate student Diane Packett conducted the study, which indicates conservation efforts should extend to smaller forested lands to help stabilize declining migratory bird populations. There are strategies for conserving forest for migratory birds, but those strategies emphasize the largest...

HARRISBURG, Pa., July 10 /PRNewswire-USNewswire/ -- Hunters will see similar dove and early Canada goose seasons and bag limits, both of which open Sept. 1, as part of Pennsylvania's 2009-10 migratory bird seasons announced today by Pennsylvania Game Commission Executive Director Carl G. Roe. Dove hunters, once again, will have the opportunity to participate in a triple-split season. During the first season (Sept. 1-26), hunting will start at noon and close at sunset daily. The second and...

Climate change could result in massive displacements by mid-century, according to a new report from climate change experts at Columbia University, the United Nations University and CARE International. "Unless aggressive measures are taken to halt global warming, the consequences for human migration and displacement could reach a scope and scale that vastly exceed anything that has occurred before," researchers wrote in the report "In Search of Shelter". "Climate change is already contributing...

Smithsonian Institution scientists say the birds that struck a plane in New York, forcing it into the Hudson River in January, were migratory Canadian geese. The researchers said they examined the feather remains from the Jan. 15 US Airways Flight 1549 bird strike and determined the geese were from a migratory, rather than resident, population. Scientists in the Feather Identification Laboratory at the Smithsonian's National Museum of Natural History said they used molecular genetic...

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...
