Osprey on Oso Creek

They eat fish. They fly "30-130 feet above the water and catch fish by dive-bombing down, adjusting the angle of flight to account for the distortion of the fish's image caused by refraction." Below is an animation made from a photo I took. The call may or may not be accurate. Ospreys make "alarm calls, guard calls, begging calls, and courtship calls." Quite an elaborate vocabulary.
