A species of bird found in Central and South America is able to supply its young with a steady diet of wasp larvae, evading stings from defending workers by using physical, not chemical tactics as previously thought, Simon Fraser University biologists have found. Continue reading
JUNEAU, Alaska — Audubon Society has collated and interpreted information from databases and decades of government surveys to create an interactive map of important areas for more than 33 million seabirds and 150 species along North America’s Pacific Coast. A great number of those areas are in Alaska. Continue reading
Birds that get their sustenance from eating dead animals are the focus of a local study aimed at keeping them alive.
Vultures, or scavenging birds that feed on carrion, have been on the decline in recent decades in many places across the globe. Jim Beasley, an assistant research scientist at the Savannah River Ecology Laboratory, wants to make sure that buzzards stick around in Georgia and South Carolina.
“Vultures are one of the species people tend to turn a blind eye to. They don’t have a lot of relevance to people,” said Beasley, one of several scientists leading a study that’s looking for a method to protect vultures.
Farmers and wildlife enthusiasts have rallied behind one of the English countryside’s most threatened birds, the turtle dove, after a terrible year for the species.
The farmland bird, closely associated with the festive season by the words to seasonal song Twelve Days of Christmas, is one of the fastest declining species in the country and conservationists at the RSPB say this year has been its worst yet. Continue reading
It’s considered the bedrock of the theory of evolution, but after more than 150 years, researchers at Oxford University in England, LSU and Tulane University have poked a hole in one aspect of Charles Darwin’s “Origin of Species.”
It was once thought that similar species living near each other evolved in order to avoid competition. Oxford researchers, with an assist from LSU, are now saying that’s not always the case. Continue reading
Humans often rear their children with help from family and friends. But why would such a strategy evolve? What could we possibly get out of rearing somebody else’s child? Now, scientists believe that they’ve unraveled this mystery — at least when it comes to birds. In some species, birds temporarily forgo having chicks so that they can help their family members raise their children. Here’s why this “cooperative breeding” strategy might have evolved.
