I've known crows were smart for a long time (one managed to con me out of my SS# and is still making Discover card charges to this day) but I didn't realize how much they liked to play in the snow.
Look at these two guys on a snowy Lada. They're sliding down the windshield and rear window like a ski slope, rolling around, making Snow Crow Angels. It looks like they're having a blast. I guess the snow means Russian Crow School is closed, so that explains why they're out playing around in the middle of the day.
