Devotion to Rearing Chicks can Come at a Cost for Migratory Birds

Birds that have to work harder during breeding season will feel the effects of their exertions the following year, according to research by Oxford University scientists. A new study published in the Journal of Animal Ecology found that migratory seabirds suffered negative repercussions when they had to spend more time rearing chicks, including decreased breeding success when […]

Migrating birds speed up in spring

It turns out being the early bird really does have its advantages. A new study in The Auk: Ornithological Advances shows that migrating birds fly faster and put more effort into staying on course in spring than in fall, racing to arrive to their breeding grounds as soon as possible to get an edge in raising the […]

Bat ‘Super Immunity’ Could Help Protect People

For the first time researchers have uncovered a unique ability in bats which allows them to carry but remain unaffected by lethal diseases. Unlike humans, bats keep their immune systems switched on 24/7 and scientists believe this could hold the key to protecting people from deadly diseases like Ebola. Bats are a natural host for […]

How Birds Unlock Their Super-sense, Ultraviolet Vision

The ability of finches, sparrows, and many other birds to see a visual world hidden to us is explained in a study published in the journal eLife. Birds can be divided into those that can see ultraviolet (UV) light and those that cannot. Those that can live in a sensory world apart, able to transmit and […]

Alaska’s Shorebirds Exposed to Mercury

Shorebirds breeding in Alaska are being exposed to mercury at levels that could put their populations at risk, according to new research from The Condor: Ornithological Applications. Thanks to atmospheric circulation and other factors, the mercury that we deposit into the environment tends to accumulate in the Arctic. Mercury exposure can reduce birds’ reproductive success and […]

Bats Take Dangerous Flight Into the Wind Farm

Wind turbines attract bats. They seem to appear particularly appealing to female noctule bats in early summer. In a pilot study, researchers of the German Leibniz Institute for Zoo and Wildlife Research in Berlin noticed this when they tracked the flight paths of noctule bats, Nyctalus noctula, using the latest GPS tracking devices. The bats […]

City Birds vs. Country Birds

Birds living in urban environments are smarter than birds from rural environments. But, why do city birds have the edge over their country friends? They adapted to their urban environments enabling them to exploit new resources more favorably then their rural counterparts, say a team of all-McGill University researchers. In a first-ever study to find […]

Bird Language

All language, human and otherwise, revolves around turning meaningless sounds into something more. It’s widely accepted that many non-human animals use what’s called referential communication — specific sounds mean specific things to the receiver. Beyond that, there are two kinds of syntax that make speech more complicated, but also more useful: phonological and compositional. Humans have […]
