Earlier this summer I would hear a bird that sounded like a hawk and I would run out, ready to flush my birds from their run back to their coop - only to see that it wasn't a raptor but some kind of song bird. A jay, maybe? I don't see well but it had a longish tail, and was small, not like a red-tail anyway. Does anyone know if jays or other harmless birds call like this to warn of a raptor? It would call and call untill I came out and then fly away.
Blue jays frequently mimic red tail hawks.
