The chipmunk was out for the first time and didn't believe his good luck in finding all that food under the bird feeder. He tried to put it ALL in his pouches. As the snow melts it uncovers seeds that were spilled by starlings and blue jays and covered up before the rabbits, squirrels, and birds got to them. There's a feast down there.
Does he really have pouches? In his cheeks are they? I've never heard of that but then we don't have chipmunks. And by the sounds of it, we're lucky we don't!
