How challenges help birds develop street-smarts - Entrepreneur Generations

Life is a lot harder for birds living in cities, but the challenges have apparently sharpened some birds' wits and made them smarter than rural birds. Read how in this article in Aeon by Menno Schilthuizen, an excerpt from his upcoming book Darwin Comes to Town: How the Urban Jungle Drives Evolution.

Some adaptations he describes seem sensible, and some almost defy belief. Carrion crows in the Japanese city of Sendai, for example, figured out an excellent way to break open tough-to-open walnuts. The local walnuts are too tough for them to crack, so country crows fly high and drop the nuts on rocks to break them. Sendai crows, though, realized the nuts would crack easier when dropped under the wheels of slow-moving cars.
