Sula variegata

Peruvian Booby

  • Order: Suliformes
  • Family: Sulidae

Authors:

The Peruvian Booby is a brown-and-white Sulid of the Humboldt Current off western South America. Like the Blue-footed Booby (Sula nebouxii), the Peruvian has brown upperparts, a gray bill, and white head and underparts. Peruvian, however, has gray rather than blue legs, a whiter head, more white mottling on the upperwings, and no white patch at the center of the lower back. This species breeds from northern Peru to central Chile on small coastal islands on cliff ledges or bare ground. While generally rather sedentary, El Niño events may trigger massive dispersal and vagrancy north to Colombia and south to southern Chile. During these events, the upwelling patterns of coastal Peru and Chile are altered, and the food sources that the Peruvian Booby and other seabirds depend on are effectively cut off. Typically, however, this species feeds in groups, often with other seabirds, by plunge-diving in pursuit of schooling fish.
