I was sent photos (link below) posted on the Texas bird list of a buteo from the other day to look over. Several people had commented already on it, and the ID's ranged from juvenile Ferruginous, Ferruginous x Red-tail Hybrid, Harlan's Red-tailed Hawk, and Krider's Red-tailed Hawk. The bird is still being discussed and debated and several people are trying to get more photos to positively identify it. Since I sometimes avoid getting into discussions on birds like this for several reasons, I will comment here on it. 

It is not necessary to aquire more photos of the bird, it is fully identifiable as an adult Krider's Red-tail from the photos gathered. But nicer photos in the future would be nice to look at anyway. Note the whitish head, unmarked underside, very faint rufous patagials, and the pinkish tail. Adult male Krider's especially can be this pale and unmarked. Also, the shape is perfect for Red-tail and there is nothing to suggest Ferruginous, hybrid, or light Harlan's. Anyway, just thought I'd post this here for anyone interested...
