evolution on the roadkill

It's no secret that roadside flying can be dangerous for birds. But new research suggests they may be getting a little help from a surprising source -- evolution.

After a 30-year study of cliff swallows, which often nest under bridges and overpasses, researchers in Nebraska found that the number of birds killed by vehicles has steadily declined since the 1980s.
