Muskrat & Beaver

Muskrat

Muskrats are common across the state. While considerably bigger than plain old rats, they are nowhere near the size of beavers, which can get to 50 pounds. Muskrats have tails that are slightly flattened from side to side, unlike beavers which have broad flat tails. Both animals build conical houses in the water, but only beavers build dams.

Beaver

Beavers are once again common throughout the state and have supported an annual trapping season since 1970. This is not an animal that you want too close to your house though, as their dam-building can cause flooding, and they can do a great deal of damage to trees and vegetation.

Osprey

Osprey - note the under-wing patterning, see Bald Eagle below

Ospreys, or "Fish Hawks", are surprisingly common, and can be found just about anywhere. You'll typically see them flying high over the water from a tree on one side to a tree on the other, occasionally diving down on some unlucky fish. Ospreys are usually seen alone, but mating pairs stay together, and I think young siblings stay together for a while as well. Ospreys are one of the biggest birds that you are likely to see. A single species has an almost worldwide distribution - pretty much everywhere except Australia.
