Justification of Red List Category
Although the population of this species is now stable or perhaps even increasing, it is likely to still be recovering after dramatic declines in the El Nino year of 1998. It could suffer similar declines in the future if conditions were repeated, for these reasons it is classified as Near Threatened.
The most recent population estimate places it at 100,000-1,000,000 individuals.
It is likely to have been as badly affected by the El Niño event of 1998 as other Humboldt Current species such as Inca Tern Larosterna inca, and although the population is thought to be increasing (Wetlands International 2006), declines over 36 years (three generations) are thought to have been in the region of 10-19%.
This species is restricted to the coast of central Peru and Chile. A new register at Isla Foca (Northern Peru) extends its breeding range (Figueroa and Stucchi 2011). Although the population may currently exceed 500,000 mature individuals (del Hoyo et al. 1992), this is a fraction of former numbers and numbers fluctuate greatly in association with El Niño, and with numbers of schooling anchoveta Engraulis ringens.
It breeds in large colonies on rocky coasts, feeding in shallow offshore waters along the coast on small schooling fish (del Hoyo et al. 1992).
It is likely to have been as badly affected by the El Niño event of 1998 as other Humboldt Current species such as Inca Tern Larosterna inca, which declines over this period approached 30%. Pelicans are notoriously susceptible to disturbance at breeding colonies, either intentional (e.g. by fishermen), or unintentional (e.g. by tourists).
Conservation Actions Underway
None is known.
Identification. Average weight 7 kg; length 1.5 m. Dark in colour with a white stripe from the top of the bill to the crown and down the sides of the neck; pale upperwings; dark brown patch on humerals; long tufted feathers on head; facial skin dark with restricted pink around the eye; reddish bill tip; bill base yellow; blue striped gular pouch that is brighter during its breeding season. Similar species. Used to be considered a subspecies of Pelecanus occidentalis but differs in its larger size and greater length.
