But just a few weeks ago, all six birds were playing in the snow, “which they absolutely love,” says Osvath. “They do all the classical things, sliding down a hill, going back up, sliding down again. Sometimes on their backs with a stick in their feet. You can throw snowballs at them, and they all line up and try to catch them, jumping as high as possible. Sometimes one raven will walk over to another and just grab a leg and yank it. Then the other will grab a leg, too, and they’ll both lose balance and fall over in the snow, boom!
