Last week at a local preserve we watched as two distant Northern Harrier juveniles played at aerial combat, or so it seemed. They coursed around the large preserve but never came close to us. At one point a Cooper's Hawk was also seen divebombing one of the harriers. Eventually, as we stood on the edge of a field, one of the harriers suddenly popped up and flew across the path in front of us. I managed to grab a shot just before he exited my frame, and have added some canvas to the left. From looking at the bird, it appears that this juvie was the victim of an aerial poop attack. I know birds will do that to drive invaders from their nests. I don't know if they do it in play, nor do I know if the bombardier was the other harrier or the Coopers. I have a version where I removed the whitewash, but have left it in this frame.
