The Harris's Hawk is a buteo (contrast with an accipiter like the Cooper's), which means it has longer and broader wings relative to its body size that help it glide with minimal exertion.
This Harris's Hawk Was a good 80 feet away, at the top of a very tall palm tree. It was exceedingly bright out as well, but even without the ideal conditions this was still a neat experience. It was very windy and you can see him catching the thermals to rise up without even beating his wings.
Here you can see the whites on the tail, both at the base and the tip. With the yellows legs and beak, rusty shoulders and thighs, and dark wings, the Harris' Hawk has got to be one of the more intricately colored raptors in North America.
