This video from the USA says about itself:

Eastern Screech Owls do an amazing job of blending in with the trees they select to perch on – this is a great example of a red morph female who have a little more challenge finding a place to blend in. In this case the reddish and tan colors of mature Palmetto Palms do just fine. This video is un-altered so you can see the natural contrast and colors. It is rare that I see them outside of the breeding season when their activity is focused on the nest box. But once in awhile I’ll find one on their favorite perch outside the breeding season. She is sitting on the end of a broken branch and if threatened will transform her appearance to a tree branch.
