I would say Northern Harrier on the first one, but the second one I'm not as sure on.

First is definitely female Northern Harrier, second looks like Red-shouldered Hawk IMO.

Second bird is a Red-tailed Hawk (rufous form of the western subsp. calcurus).

This bird is way to massive and bulky for a Red-shouldered. and the breast pattern is different, and the wings are plain brown (checkered black and white in adult Red-shouldered)

That chest pattern looks off for a Red-tailed Hawk. Anybody think that it looks like it could be a Ferruginous Hawk? It's a big heavy bird. Not a clear view of the gape but it looks long.

I believe chest pattern is pretty typical for calurus ssp Red-tailed Hawk. As for Ferruginous, they're supposed to be feathered down the tarsi, which on this bird, seem to be pretty naked.

I agree on Red-tailed Hawk for the second bird (I had to consult my field guides, the breast color is quite different from the eastern forms that I am familiar with). Ferruginous would have a clean white breast, among other features already mentioned.

My problem with this being a Red-tailed Hawk is that it is not one of the darker morph variations of the Western RTH B.j.calurus and so a belly band should be readily visible on it. I agree that the lack of readily visible feathered Tarsi is a problem on whether it is a FH or not. Doesn't look like a Swainsons either so I guess I will have to go with the default North American Buteo, the RTH.

BTW, Ferruginous Hawks can have heavily streaked breasts and there are dark rufous morph FHs also pictured in Wheeler's Western Edition.
