Rooftop wiretap aims to learn what crows gossip about at dusk

Thu, 14 Dec 2017 08:16:00 EST

What are crows saying when their loud cawing fills a dark winter’s evening? Despite the inescapable ruckus, nobody knows for sure. Birds congregate daily before and after sleep, and they make some noise, but what might be happening in those brains is a mystery.Curious about these raucous exchanges, researchers at the University of Washington Bothell are listening in. They are placing equipment on the roof of their building — a meeting place for some of the thousands of crows that sleep in nearby campus trees — and using a sort of computerized eavesdropping to study the relationship between calls and the birds’ behavior.(image)

University of Florida study: Bird evolves virtually overnight to keep up with invasive prey

Tue, 12 Dec 2017 08:10:00 EST

The federally endangered bird, the snail kite, was faced with an interesting dilemma: The island apple snail was good to eat, but about two to five times bigger than the native snail that the bird usually consumed. What’s a hungry bird to do? Evolve – quickly.A study by a team of University of Florida researchers has found that in about 10 years, the snail kite has evolved to develop a larger beak as its new prey, the island apple snail, proliferated and became invasive. The study is published in Nature Ecology & Evolution.(image)
