Tree swallows expose state of our climate

For many of us, birds are an interesting distraction or a sign of spring. For Fran Bonier and her former master's student Amelia Cox, bird populations provide vital data about the health of the world. Their new research adds ...

Preserved leaves reveal 7000 years of rainfall and drought

A study by University of Adelaide researchers and Queensland Government scientists has revealed what south-east Queensland's rainfall was like over the last 7000 years – including several severe droughts worse and longer ...

Barn swallows may indeed have evolved alongside humans

The evolution of barn swallows, a bird ubiquitous to bridges and sheds around the world, might be even more closely tied to humans than previously thought, according to new study from the University of Colorado Boulder.

Getting to the root of long-term tree swallow declines

Aerial insectivores—birds that hunt for insect prey on the wing—are declining across North America. Conserving vulnerable species such as these requires a good understanding of the factors impacting them at every stage ...

How does agriculture affect vulnerable insect-eating birds?

Aerial insectivores—birds that hunt for insect prey on the wing—are declining across North America as agricultural intensification leads to diminishing insect abundance and diversity in many areas. A new study from The ...

Researcher studies birds that break all the mating rules

What can the mating behavior of birds tell us about evolution, climate change and species survival? For Peter Dunn, UWM distinguished professor of biological sciences, bird-watching offers clues to overarching ecological ...

Barn swallow behavior shift may be evolutionary

Most of our understanding about evolutionary changes and the formation of new animal species is based on the historical record. But a relatively new population of barn swallows in Argentina may help scientists see those changes ...

Quality, not quantity, of diet is key to health of baby birds

In a new study that upends the way ornithologists think about a young bird's diet – but won't shock parents used to scanning the nutritional profile of their children's food – Cornell researchers have found that when ...
