Seriously, if you discount things seen from my house, car or in a zoo, it's nothing. Squirrels, skunks, chipmunks, raccoons, and a bunch of unexciting birds.
Only interesting thing is a red tailed hawk. One sat on the peak of my roof one day a few summers ago. Big MoFo. Oh, and some eagles during a kayaking thing I did in Maine.
Other than that, pretty much zip. Boston and its environs has been civilized for too long. We had alot of excitement up here a few years ago when a bear swam across the Cape Cod canal and was wandering around down there. Reportedly the first bear on the Cape since 1837.
