I found this Caracara nest just outside of Tucson and was fortunate to be there during feeding time. This was full frame. I have another version of a later cropped frame with the emphasis on the mom, but think I like the inclusion of the chick better. Mom is carrying 2 chicks from another nest to feed her own young. Nature is brutal sometimes.
