PIQUERO - Peruvian Booby


Kingdom: Animalia
Phylum: Chordata
Class: Aves
Order: Pelicaniformes
Family: Sulidae
Genus: Sula
Species: S. variegata



This is another endemic bird
from the west coast of South America.
Luckyly, this is the second most abundant seabird species that inhabits the Peruvian Coast and the second most important guano-producing seabird.

Peruvian Boobies breed throughout the year. Main breeding season is from September to March and most pairs attempt to breed for a second time during the year depending on food availability. The clutch size varies from one to four eggs, but clutches of two or three eggs are usually found. Eggs are pale blue and are incubated during 4 to 5 weeks, both adults share the nest attendance. The rearing period lasts about 3 months. Breeding success depends on food availability and is related to colony location, colony size and timing of breeding.

The ones I found in Paracas were having new family, found some young ones with a brownish head and body instead of the characteristic white.

The boobies that are all brown are juveniles. Juvenile birds of many species have pretty drab plumage to make them less visible to predators.
