Posts Tagged ‘aerial dogfight’

A juvenile Bald Eagle (Haliaeetus leucocephalus) tried to steal a fish from an Osprey (Pandion haliaetus) on Thursday at Occoquan Bay National Wildlife Refuge and chased it across the sky. It was quite an aerial dogfight. In the end, I think that the osprey dropped the fish and both birds ended up “empty-handed.”

Ospreys migrate away from my area for the winter and I was delighted to see that they had returned. I spotted at least a half-dozen or more ospreys and they were both active and vocal. Ospreys have high-pitched, distinctive voices that the Cornell Lab of Ornithology described in these words, ” Their calls can be given as a slow succession of chirps during flight or as an alarm call—or strung together into a series that rises in intensity and then falls away, similar to the sound of a whistling kettle taken rapidly off a stove.” Here is a link to a Cornell Lab webpage where you can listen to recordings of various osprey calls.

These three photos give you a general sense of the chase. In the first shot, you can definitely see the “prize,” the fish that the osprey had caught. In the second shot, the eagle has closed the distance separating it from the osprey. In the third shot, the osprey is doing its best to maneuver away from the eagle, but the eagle was able to match the osprey turn by turn. All of this took place over the water and eventually the two birds flew out of range.
