Interesting Animal - Swallows
According to Dr Charles Brown, of the University of Tulsa in Oklahoma, swallows are evolving to avoid getting hit by cars.
(A study carried out over several years in Keith County, Nebraska, has shown a sharp reduction in the number of swallows killed on the roads, and the results seem to show that natural selection has favoured birds that are better able to get out of the way of oncoming cars and trucks.
Now if only hedgehogs would evolve too.)
