This eastern screech owl is barley visible at the entrance to a tree hole - thanks to its perfectly evolved camouflage.
The nocturnal hunter was photographed in Georgia’s Okefenokee Swamp by snapper Graham McGeorge.
He said: "They are masters of disguise so you need to have a sharp eye in order to see them.
"I found this one that was living in a hole in the tree that woodpeckers usually make.
"They are easily spooked and every slight movement I made would scare the owl and send it back inside the hole.

"After 30 minutes or so it would come back out."
According to the National Geographic: “Its whinnying and trilling songs are familiar but its vocalisations also include rasps, barks, hoots, chuckles and screeches.”
