Harlan's Red-tailed Hawk

This is a Harlan's Red-tailed Hawk that has been visiting in the Canon City, CO area for several days. It was quite sensitive and did not tolerate viewing from inside my car and over a hundred feet away so difficult to get pics. It vocalized it's displeasure at my viewing and photographing it both while perched and flying as can be seen in these pics with it's bill open as it screams. As shown it has a lot of white on it's face but very little on it's upperparts. It's tail is also quite whitish on the underside. It has a lot of blackish markings on it's underside. SeEtta
