Looking toward the future, researchers found migrating birds in the Western Hemisphere will likely face challenges as a result of a changing climate in the next 40 to 50 years,...

A few years ago, University of Guelph researcher Elizabeth Gow’s work wouldn’t have been possible. But improvements in technology allowed biologists to fit tiny tree swallows (Tachycineta bicolor)with even tinier...

Changing wind patterns due to climate change could bring mixed results for migrating birds. Under future climate scenarios, researchers found, North American birds may find it harder to migrate southward...

These reindeer can’t fly, but using airborne drones, researchers discovered lots of interesting things about how they move on the ground. In what they say is the first paper to...

The migration of the monarch butterfly (Danaus plexippus), from the highland of Mexico to fields and backyards throughout North America is well known. But what about the journey of the...

Looking across the Wyoming landscape, it might seem like mule deer (Odocoileus hemionus) could pick just about anywhere to cross between the high country, where they spend the summer, to...

Using weather radar to study North American bird migrations, researchers at the Cornell Lab of Ornithology made a surprising discovery: birds leaving the United States on long, hazardous journeys to...

Weather radar is usually collected by the National Weather Service to help people know what to wear outside or if any big storms are coming, but it can also help...

Common nighthawks (Chordeiles minor) have declined about 80 percent since 1968, but researchers hadn’t yet known where they go for the winter — information that could be important in understanding...

Most piping plover (Charadrius melodus) research focuses on disturbances during their breeding season, but researchers recently found anthropogenic disturbances can also have consequences for the shorebirds where they overwinter. “The...
