Evolution in nature with a little help

I seem to be on a roll lately on how humans affect nature. Now today I have two articles, both on how have played and play a role in the evolution of birds.

This first article is over at Scientific American and is entitled “Backyard Feeders Driving Bird Evolution” by Karen Hopkins. It looks at two sub-species of the European Blackcaps and their food source.

The other article looks at how humans can help birds in relation to bird baths. It’s entitled “Stones in Bird Baths are a GOOD Idea! by Laura Simpson at the Environmental News Network via Care2.

Food & water for thought!
