I've seen a woodchuck climb a tree.

I've seen a red fox climb a tree chasing a squirrel (though the tree was at an angle, but he got pretty high up).

I've seen a flock of 30 turkeys try to fly over the New York State thruway. They barely cleared my car, and about 10 of them got hit by the tractor trailor behind me.

Had a muskrat climb over my feet while trout fishing.
