My best image of these guys to date. Captured on the plains of Colorado yesterday afternoon, I was finally able to get one of these guys curious enough to stop for a picture before bolting off across the prairie. Would've liked to not have the horizon cutting through the head but I dared not get out of the car to get a better angle. 20D, 400DO + 1.4xTC, f7.1, 1/1250s, ISO 400.
