I didn't get to positively identify this one because I saw him flying through the tress, but based on the approximate size (roughly two feet tall or more), it must have been a Great Horned. I saw one down in Nashville during the day, just hanging out on a branch. This one was up in the trees when my dog and I came blundering along the path, and he decided to relocate deeper into the woods.
Big birds are impressive!
