Eastern screech owl
The Eastern screech owl is a master of disguise, according to the Cornell Lab Bird Academy. Its brown, gray and white coloring blends in beautifully with the bark of trees, where the owl hides in cavities. It also has feathers sticking up from its head that break up its outline and make it harder to see, explains the University of California, Santa Barbara.
"Even when the owl perches on a branch, it is still difficult to distinguish it from a broken snag. When hidden like this, they’re hard for even experienced birders to spot," the Bird Academy says.
