Here's an easier one

 

It’s an eastern screech-owl.  You won’t be able to see him in this picture, I’m just showing you the tree.

.

If you know where to look, he’s just starting to get visible in this one.

.

.

.

.

.

On the right side of the tree.

.

.

.

.

.

In a hole where a branch used to be.

.

.

.

.

.

Right in the middle of the shot.

.

.

.

.

.

In plain sight!

.

.

.

.

.

A little owl face.

Once you see this one, it’s easy, right?
