Great Tits Are Evolving

Great Tits Are Evolving Longer Beaks Because of Bird Feeders
By Kristin Hugo On 10/19/17 at 2:56 PM

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 is behind this trend. 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. 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.

It is a great looking Tit.  I wish we had tits like that down south here.
