The first thought i had when seeing the photo was thats an owl...i zoomed in, and the first thing that stunned me was that he is decorated in the original tree-bark camouflage. The design of nature is nothing short of amazing.
Barred Owl talks like this : HO ,ho ,HO ,ho,HO,ho , HO AWWWWWW. We have always had several of them around. Barreds' and Great Horned Owls are fun to imitate , makes them worry that there are intruders trying to take their territory.
