Scarlet Macaws at a Mineral Lick, Tambopata National Reserve, Peru
Stuart Hahn, MD

The interactions of scarlet macaws around clay licks have been the focus of decades of extensive research. The iconic parrots seem to get sodium and other minerals from licking the clay deposits, and their use of the licks appears related to climate variations, food supply, and breeding times. scarlet macaws inhabit tropical rainforest regions of the Americas. This large and beautiful species has suffered major population declines in recent years.
