I Am So Tempted to Say that These European Crows Are Racists

In Europe, there are two groups of crows who are almost identical — except for for thing. Carrion crows are all black, while hooded crows have patches of gray. Each group prefers to mate with their own color. It sounds like what humans would call racism, but instead it's a lesson in the limits of anthropomorphism. » 6/20/14 5:35pm 6/20/14 5:35pm

Crows are among the planet's most intelligent animals, teaching their young to use tools for foraging and banding together to fight off intruders.

Corvids: The Birds Who Think Like Humans

Someday I will come up with a good reason why I am friends with the neighborhood crows.

I had heard that these creatures, part of a larger family of birds… » 12/18/12 3:22pm 12/18/12 3:22pm
