An intruder! (a backblip)

This hawk appeared in the backyard buffet recently, and many of the smaller birds I usually see, like the chickadees, titmice, and even the downy woodpecker, have not been coming around so often. Although I suspected it was in the neighborhood, I hadn't actually seen the hawk until today when it flew in and boldly landed on the top of the old swing set. The little birds haven't been happy about it, and neither have I!

I don't know what kind of hawk it is, but if you know, please leave a comment.
