The Brown Booby, Sula leucogaster, is a member of the Sulidae Family of Boobies and Gannets. They are mid-sized in stature. In Mexico they are limited to the coastal regions within the Atlantic Slope in the state of Campeche, and they are found in all waters within the Pacific Slope at elevations below 100 m (330 feet). From a conservation perspective the Brown Booby is currently considered to be of Least Concern with stable, widely distributed populations. They roost on rocky islets and shorelines in areas with little or no vegetation. They are shallow water plunge divers with their diet consisting primarily of fish and a limited amount of squid.
