This photo was taken at the Tucson Zoo. I must have stood there watching these birds for something like 10 minutes. These birds have been at this zoo for a long time and you'd think they would be best of friends by now. All they were doing is what seemed to be yelling at each other. By the time I was leaving, these birds were starting to fight (or mate) with each other, as displayed in this photo. The fighting, however, didn't seem to be very rough though.
