I always thought the red tail was pretty unmistakable. We have a ton of red tails around here, two that regular stalk our coop. It didn't look like the typical red tail we see around here. I was thrown off by how close it let me get. We have about 2 acres of land, long and narrow, our house its towards the front, coop towards the back and the hawks will usually take off once I open the door and step out.
