I don't know what kind of hawk this is...I thought it was this one that I used to see out at the strip pits, but when it flew it did not have the white on the tail feathers. I am thinking it is a Red-tailed hawk. When it flew, I could see red at the base of the tail feathers on the back. But other than that bit of red, his back was dark. The way he flew I did not get a good look at his underwings... He was a pretty good sized hawk.
Edited to add: Take a look HERE at the Red -tailed hawk...then scroll down and look through all the other photos, got numbers 8 and 9. To add to the confusion, go HERE and then scroll down and look at the dark morph of the Swainson's Hawk. I still believe it is a Red-tailed because there are so many in the area and we are just east of the range of the Swainson Hawk's area.
