But the British ones have slightly longer beaks, scientists say, and the reason might be British humans’ embrace of bird feeders.

Longer beaks may be evolving in U.K. great tits because of the widespread use of bird feeders in the country.

Even more surprising is that historical data indicated this trend towards longer beaks in British tits was quite recent -- and it occurred quickly.

A few years ago the depth and thickness of beaks of various species of Darwin's finches, the birds forever linked in the textbooks to adaptive radiation by natural selection, were found to ...

Certain birds in the U.K. have longer beaks than their non-U.K. brethren of the same species. Evolutionary biologists suggest that it’s the British people’s fondness for setting out bird ...

In Britain, significant numbers of blue tits, a close relative of black-capped chickadees, have been observed with beak deformities. In all, 36 species with deformed beaks have been documented there.

The hobby appears to be directly impacting evolution. Researchers studied beak lengths of great tits in the U.K., where bird feeders are popular, and in the Netherlands, where they are not.

Modern gulls, with their large eyes, long beaks and distinctly ancient-looking and bony faces, descended from animals such as the velociraptor and T. Rex.

Bigger is better if you're a male hummingbird. Scientists have discovered that males grow longer, sharper beaks than females as they age—which they then use to stab each other in the throat ...

Great Tits May Be Evolving Bigger Beaks. Here's Why. Since Darwin's time, birds have served as models for the wonders of evolution—and this study was no exception.

Certain birds in the U.K. have longer beaks than their non-U.K. brethren of the same species. Evolutionary biologists suggest that it’s the British people’s fondness for setting out bird feeders that ...
