ID tip
The Peruvian booby has brown upperparts and a white head and underparts. 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 and grey webbed feet. This differentiates them from characteristic coloring of the blue-footed and red-footed boobies. Female boobies tend to be larger than their male counterparts: their bodies an average of 19% heavier, and their wings 4% larger. Voice: Female Peruvian boobies have a range of vocalizations; from trumpet-like quacks to honks. The male booby, on the other hand, tends to whistle. This kind of auditory communication is unique to adult members of the species, as it takes a few years to be able to produce such vocalizations.

About the Peruvian Booby
The Peruvian booby is an endemic bird of the Peruvian current, and an important predator of the marine community to which it belongs. Its distribution is much less widespread than other closely related booby species. It is the most abundant seabird species that inhabits the Peruvian coast and the second most important guano-producing seabird. During the mid-twentieth century, the Peruvian booby population reached 3 million birds.
