Peruvian Pelican

These birds are dark in colour with a white stripe from the top of the bill up to the crown and down the sides of the neck. They have long tufted feathers on the top of their heads. It was previously considered a subspecies of the brown pelican (Pelecanus occidentalis). The Peruvian pelican is considerably larger, ranging from about 5 to 7 kg (11–15 lb) in weight, 137 to 152 cm (4.5–5.0 ft) in length and with a wingspan of about 228 cm (7.5 ft). Compared to the brown pelican, it also has proportionally longer crest feathers, as well as differences in the colours of the gular pouch, beak, scapulars and greater wing coverts.

Peruvian pelicans feed on several species of fish. Unlike the brown pelican, they never dive from a great height to catch its food, instead diving from a shallow height or feeding while swimming on the surface. On occasion they may take other food items, such as nestling of imperial shags, young Peruvian diving petrels, gray gulls and cannibalize unrelated chicks of their own species. They also feed on pelagic species such as anchovies. In fact, those in the northern Humboldt Current System feed almost exclusively on one species, the Peruvian anchoveta. The birds feed around cold-water upwellings, being found along the Humboldt Current.
