I found the fact that owls are such loners interesting and quite a contrast to the many birds who flock and move together during the non-breeding season. I had always had an idea that owls were loners, but did not realize the degree to which they are loners. It was interesting that, as an exception, short-eared owls are know to form communal roosts. In regard to family life, the concept of the young "branching" was interesting. I am really enjoying this course. All kinds of new information!
