Fluffy Eastern Kingbird
I photographed this fluffy Eastern Kingbird this past April while at the Sequoyah National Wildlife Refuge in Oklahoma. I read that birds fluff up in the cold to trap as much air in their feathers as possible. The more trapped air, the warmer the bird.

How I Got The Photo – Fluffy Eastern Kingbird
I was driving near the Tuff Boat Ramp when I saw this bird land on a small tree between the auto tour road and the river. I parked on the road with my camera and lens resting on a bean bag draped over the open window of my pickup.
