Member of the family Procellariidae are small to medium-sized seabirds. There are no obvious differences between the sexes, although females tend to be smaller. Procellariids have a characteristic tubular nasal passage, which is used for olfaction. The plumage of the procellariids is usually dull, with grays, blues, blacks and browns being the usual colors, although some species have striking patterns (such as the Cape petrel).
The wings of all species are long and stiff. In some species of shearwater the wings are also used to power the birds underwater while diving for prey. Procellariids generally have weak legs. The exception to this is the two species of giant petrel, which like the albatrosses, have strong legs used to feed on land. There are 7 genera and 23 species of the family Procellaridae known to occur in Peru. Photo: Cape Petrel. Creative Commons.
