I forgot to mention a Great Gray Owl which was a rare visitor to Jefferson County in Northern New York several years ago. I will never forget the thrill of seeing that Owl!
I have seen a Great Horned Owl in Syracuse, a Snowy Owl this winter near Onondaga Lake in Syracuse, a Barred Owl several times while camping in Ontario, Canada ( one time with chicks in a nesting hole high up a dead tree) and an Eastern Screech Owl several times as they nest very close to our house which borders a heavily wooded city park in Syracuse.
