Spoonbills playing or fighting.

"Feed on small fish, some plant material, amphibians, aquatic amphibians, insects, crustaceans. The Spoonbill's have a very long bill that is shaped like a spoon. These birds move their beaks back and forth, which allows the bird to catch its prey. In addition, these birds also make very weird noises when they eat." (info from Ft. Worth Zoo website)
