I wake to screaming hawks each day. They generally hit my treetops in the afternoon and/or evening too. I once counted 8 in the air at one time and was told they were chicken hawks. So why do my free-ranging ducks and chickens seem completely unaffected? Why have I never seen a hawk dive at my girls? On overcast days, hawks really seem to gather around my home. My yard has many very large old trees, but sometimes, the chickens are out in the open. I am assuming the hawks are hunting mice in the fields in front of and behind my home. I am in Northern Virginia where I believe red-tail hawks are common.
