(2010). Marine habitat use of Peruvian boobies: a geographic and oceanographic comparison between inshore and offshore islands. ''ICES Journal of Marine Science'' 67(5):940-951.〕 Its distribution is much less widespread than other closely related booby species. It is the most abundant seabird species that inhabits the Peruvian coast〔Bernal M, Contreras M, Ellenberg U, Garthe S, Lara-Jorquera G. (2003). Breeding distributions and abundance of seabirds on islands off north-central Chile. ''Revista Chelina de Historia Natural'' 76(2):323-333.〕 and the second most important guano-producing seabird. During the mid-twentieth century, the Peruvian booby population reached 3 million birds. ==Description== The Peruvian booby has brown upperparts, and white underparts, as well as a white head. There is noticeable white mottling on the upper side of the wings. Their wing-coverts are tipped white, creating a scale-like pattern. They have a long, pointed, grey bill. Their feet are webbed and also grey; as opposed to the characteristic colouring of the blue-footed and red-footed boobies〔Neotropical Birds Online (T. S. Schulenberg, Editor) (2010).

US: Princeton University Press.〕 Female boobies tend to be larger than their male counterparts: their bodies an average of 19% heavier, and their wings 4% larger.〔Zavalaga C, Taylor S, Dell’Omo G, Anderson D, Friesen V.
