A Range of Swainson's Hawk Images

Swainson's Hawks are in high gear these days with breeding. Most are past the egg laying stage and are feeding young ones in the nest or helping them learn to fly and hunt.  These hawks spend our winter months in places like Argentina and return to Utah around mid- to late April. I discover Swainson's Hawk nests nearly every few days as I do my daily commute to work and run errands around town. I've had a few encounters with some handsome and beautiful Swainson's recently so I thought I'd share some of the images of these awesome raptors.

Most large (buteo-type) hawks have two basic plumages, juvenile and adult. Swainson's Hawks, however, have three--juvenile, sub-adult, and adult. Swainson's Hawk adults also show slight differences between male and female. That is not typically the case for large hawks. The images I've captured in recent days include birds of all three morphs (light, intermediate, and dark), all three ages (juvenile, subadult, and adult), and male and female.

  2. Those Kingbird will not only attack a hawk but will land on their backs and peck at their heads
