We've been told over and over again how smart crows are, but they still astonish us now and then. Logically, we know that flying should be more thrilling than anything humans can do, but we all know in our hearts how much fun it is to slide down a snowy hill. This crow has commandeered a piece of trash to act as a sled! Or, more accurately, a snowboard since he stands up on it. He flies up to the top of the snow bank, then slides down on his snowboard. When the snowboard gets away, he chases after it before some other crow can get it.
Give them a little time, and the entire flock (or murder) will be raiding the garbage for flat pieces of plastic. Then they'll organize their own X games to compete with each other. After all, crows are pretty smart. -via Nag on the Lake
