We plan to stay clear of those owls!! We know we have Barn Owls, but this is the first time I have seen a grey owl with ears...kinda looks like a Furby! Thanks for the replies, I now think it is a Great Horned Owl after looking at the links. The bird does not seem small, it seems to be about the same size as a Barn Owl.
At least I got some great photos of the owls, thanks to a telephoto lense!!
