Stoic Redtail Hawk

The Red-tailed Hawk is carnivorous, and an opportunistic feeder. Its

diet is mainly composed of small mammals, birds and reptiles. Prey

varies with regional and seasonal availability, but usually includes

cottontails, rodents, pheasants and quail.[13] It may also prey on

waterfowl, bats, shrews, snakes, lizards, crustaceans, insects, and

when near the waters edge, carp and catfish.[11][14]The Red-tailed

Hawk hunts primarily from an elevated perch site. It will swoop down

from a perch to seize prey, catching birds while flying, or pursuing

prey on the ground from a low flight.[14]

Prey taken can range in size from beetles to White-tailed

Jackrabbits, which are double the weight of most Red-tails. In

captivity in winter, an average redtail will eat about 135 g (4-5 oz)

daily.[13] The Great Horned Owl occupies a similar ecological niche

nocturnally, taking similar prey. Competition may occur between the

Red-tailed Hawk and the Great Horned Owl during twilight.

I think the detail in this image is great. However, IMO the crop is too loose. I would crop it tighter, and maybe add a little contrast, and I think this would be excellent.

Just my opinion.
