I was outside this morning with the girls and a bird landed on the wire. I've never seen one like this, so I assumed it was a hawk. I couldn't see it's beak clearly, but it was watching my backyard and so I threw a few pebbles at it and chased it off. Well once it flew off I could tell it was a hawk, and then a few monites later a bunch of crows/black birds were attacking it in the air. It was screaming and trying to get away but the crows stayed on it and chased it into a tree. LOTS of noise and finally it kinda flew off like it was lopsided or something. It sure took a beating. It was a smaller hawk, no clue what breed or anything, but glad it's gone. I will be keeping an eye out but luckily this block is FILLED to the brim with crows. I had no idea they were so helpful! Any idea's for hawk deterrents? My birds are strictly free range and in the coop only at night.
