Great tits are evolving longer peckers, because of bird feeders
Researchers studied beak lengths of great tits in the U.K., where bird feeders are popular, and in the Netherlands, where they are not. They also tracked the location of tagged tits to determine how much time they spent at bird feeders. The scientists also have 70 years' worth of historical data on great tits and could discern that their beak lengths are changing with time. The study was published today in the journal Science.
