Saw an amazing goshawk-mallard interaction this evening while driving. Caught motion out of the corner of my eye immediately after noticing a flock of mallards flying toward me. A goshawk came out of nowhere and hit one of the trailing birds but only got claw on the base of a wing. They tumbled together in air for just a second with wings going in every direction!
The gos got a second grip with the second foot and set wings, gliding back away from the road with both wings set pretty high. Could not see any more struggling from the mallard at that point, so I assume it was a done deal the hawk would eat well.
