Got out this afternoon and went to one of my spots to look for the Great horned owls. Walked around a good bit and didn't see anything, but was about to head back, and then I heard the sound of one of the owls. I had a pretty good idea which tree it was in, but I searched for the longest time, and then finally, I noticed something moving up in the clump of moss. And sure enough, it just happened to be one of the great horned owls. I walked all around that huge oak, but there was only one spot that I could even see it, and this was it. It was hid very well. Shows up best on black if you have the time.
Definitely worth checking on black - he was so well camouflaged I'm surprised you found him - glad you caught the slight motion - got some awesome details on him. (and love that moss!)
