An Eagle With Ruffled Feathers

Got these from the lake this morning. More images from the last couple of trips to the lake here.

From farmyou.com: To maintain its body temperature an eagle simply changes the position of its feathers. While an eagle suns itself on a cold morning, it ruffles and rotates its feathers so that the air pockets are either opened to the air or drawn together to reduce the insulating effect.
