Very weird behavior. Pair standing on the ground amongst a group of AMCR in a patch of willows by the parking lot. About a dozen times, either of the COHAs allowed a crow to wander within 5 ft, and would then pursue the crow, either on foot or in flight. Each time the chasing COHA returned to the other COHA on the ground. I’ve never seen Accipiters behave this way before and neither appeared injured, and none of the AMCR were obviously mobbing. My best guess is the COHAs killed prey nearby and it was still on the ground.
