A friend of mine saw a dead Hawk on the road. He took them to his house to photograph them. He put them back but wanted to know what the bird was. He said it had a hawks head, mangled a bit from a car strike but a hawk. The only ones I could find that are like these are is the Red Tailed Hawk. Sad thing in my area of Arkansas is we see so many Hawks and Owls killed by car/ traffic. I have had hawks dive right across the road lane. I don't know if there is anything that could be done to help stop this but it would be nice if there was. I told my buddy that the tail feathers were not red but I can not find any other Hawk native to Arkansas/Missouri that match perfectly.
