One winter back in the mid-nineties, I was traveling around Yellowstone on a snowmobile doing sound for an NHK film crew. At one particular stop, I believe it was Black Sand Basin, several snowmobiles were parked while their drivers were viewing the hotsprings. As I walked back to my snowmobile, I witnessed a raven land on a backpack bungied to one of the parked snowmobiles. He/she deftly grabbed the zipper on top of the backpack and zipped it open. The coal black grifter then stuck it's head into the pack and pulled out a cellphone which it promptly threw to the ground. Then ducking its head into the unzipped backpack again, the black forager pulled out a fully wrapped Snickers Bar. It glanced around with bar in beak to make sure a clean getaway was possible, then flew away with the fat Snickers Bar. At that time, I was amazed to see the thoughtful process of the Yellowstone raven. Now, Dr. Alex Taylor, a scientist in the UK has empirically shown the incredible intelligence of the crow.
