Peruvian Booby

The Peruvian Booby (Sula variegata), is a seabird endemic to the Peruvian current. It is distributed only along the coast of South America from Punta Pariñas in Peru to Concepción in Chile. It is one of the most abundant species of seabird that inhabits the Peruvian Coast. By the mid twentieth century this species had an estimated population of 3 million individuals.

Peruvian Boobies breed throughout the year. Main breeding season occurs between September and March. They may breed a second time if food is abundant. Peruvian Boobies clutch size ranges from one to four pale blue eggs. Eggs are incubated for 4 to 5 weeks and both adults share the nesting duties. The young are reared for 3 months. Success in breeding depends on food availability, colony location, colony size and timing of breeding.

After El-Niño in 1982-83, it was estimated that only 200,000 species remained. In 1996, after a 13 year recovery, the population regained its number to 2.6 million birds. El-Niño 1997-98 came after the booby breeding season and caused a southward migration, decreasing its population in Peru.
