Robins, Cardinals, Chickens, Wood Peckers... and giant leaping bunnies!
Poor 'Touff. He kept wiping out in the mud in the yard while he ran around. Slightly funny, slightly terrifying. Eventually he figured out that the herb bed was dry and solid and fun to play in (yes, the fence is going back up on it as soon as the last frost has passed). He's a bit of a lug though- and ran into the wall and the boards multiple times.
Yes, I called him a "wingnut".
