Owls this for a disguise?
An eastern screech owl is barely visible at the entrance to a tree hole - thanks to its perfectly evolved camouflage.
These incredible pictures were taken by photographer Graham McGeorge, 42, in Okefenokee Swamp, Georgia.
这组照片的英文意思是，猫头鹰的巢穴入口处正好与猫头鹰的身形吻合，而且猫头鹰的颜色、羽毛纹理与周围树干极其相似，当猫头鹰站在巢穴门口的时候，仿佛镶嵌在树干上一样。
大自然就是如此的神奇美妙，摄影者是乔治亚州42岁的“Graham McGeorge”先生。
Natural camouflage: An eastern screech owl disguised in the hollow of a tree in Okefenokee Swamp, Georgia
I see YOU: Screech owls are quite common across North America but they generally go unnoticed
Hiding place: Usually solitary, screech owls nest in a tree cavity, either natural or dug out by a woodpecker
Night owl: They are strictly nocturnal, roosting during the day in their cavity nests or next to tree trunks
They don't really screech: Their call is a haunting tremolo with a descending, whinny-like quality |
