great blue heron
garter snake (twice as big as the ones that were inside!)
and there were duck type birds in the pond this morning but they were on the far side so we couldn't tell what they were. They were just definitely not mallards because they moved different, and they weren't hooded mergansers, because the male didn't have the big white feather 'fro going on.
Also, besides seeing the woodchuck, I also discovered the location of his burrow, so now I can stalk him!
