What a great shot! One of the first raptors I ever got to work with during my internship at the zoo was a Harris' Hawk. He has quite the personality! They are such beautiful birds and so unique among the other raptors. They're just great in every way and you captured a lot of their greatness in this photo!
WOW! What and incredible shot! I love how clear the hawk's face is. You can just feel the speed and power here. And Harris Hawks are among my favorites, they are such interesting hawks, they cooperatively hunt, and they "stack", exceedingly unusual raptor behavior.
