My first impression was a Great Horned Owl. I was a little surprised by Resin's Barred Owl identification. So I pulled up my photos of Great Horned Owl chicks. I still believe it is a Great Horned Owl, but rather young to be out of the nest. Judging from my photos I would guess it left the nest 10 days to two weeks younger then the Great Horned Owls chicks, in the nest I photographed. The attached photo is of chicks about the same age as the one in question. The face changed from black to brown as feathers developed with age.
