Adult dark-morph Red-tailed Hawk makes a lot more sense for this bird given
what can be seen of the tail. It looks like we can see the tail all the way to
the end and there is no narrow (adult) or broad (juvenile) subterminal dark
band. The entire underside of the tail looks pale and it appears to have very
weak if any thin dark banding, which is typical for an adult Red-tailed Hawk.
Juvenile Red-taileds show more obvious bands on the underside of the tail. To
my eye, the bill seems a bit large for a Rough-legged. With a photo angle like
Jim Leonard's, I don't think one can determine whether the bird has feathered
tarsi. When Red-taileds sit in a somewhat compressed posture, like what is
shown in Jim's photos, the lower belly feathers tend to obscure everything but
the feet of the bird. In these images, the tarsi appear to be fully hidden by
these fluffed up feathers.
