Sitting here at my computer, A bird I have earlier flying photos of just attempted to attack one of my hens. I grabbed my camera and these are the shots I got. Unfortunately I was shooting through a rain spattered window and a screen, so the quality isn't great.... but I NEED to know what type of bird this is!!! Now that I have seen it attack a hen (which got away and ran to the coop) I am about to deal with it using the SSS method. That stands for Shoot, Shovel, and SHUT UP. All of my chickens are now locked up in our chicken yard. What type of Hawk or Falcon is it????...and I need to know if it is on the protected species list!!!!! When I compare flying photo with ground photos, I'm not 100% sure I'm dealing with just one bird. HELP!!!!! I am located in Gibson City, IL which is Central IL if that helps with identification.
