This past winter I helped a friend of mine do some trapping, which I had never done before. In some fox/coyote sets and some small conibears we caught a bunch of squirrels I had never seen before. My friend is an experienced trapper, and he says I wouldn't have seen them because they are nocturnal. Has anyone seen these? They aren't like southern flying squirrels. I had never heard of nocturnal squirrels before. Why were they attracted to our traps?
