I am having a hard time figuring out if this is a Rufous Morph adult, or a Dark Morph Adult Red Tailed Hawk. I am leaning towards the Dark Morph because it is dark all over with reddish tail, yellow legs.
“Red-tailed Hawks are large hawks with typical Buteo proportions: very broad, rounded wings and a short, wide tail. Large females seen from a distance might fool you into thinking you’re seeing an eagle.” (http://www.allaboutbirds.org/guide/red-tailed_h...). Their habitat is open country and are found on fences or fence post and telephone posts/polls.
