Great-horned Owl immature almost like adult

September 26, 2011 - Today at Harrison Hills Park, Allegheny County, PA I saw one of the two immature Great-horned Owls I've been observing since the beginning of May. I haven't seen the owls for a couple of weeks before this sigting, and was glad to see this one today. It's been 4-5 months since they have fledged, and the adult is probably not feeding them anymore. So let's hope they are wise and learn to hunt for themselves.
