Pelecanoides garnotii
The Peruvian Diving Petrel (Pelecanoides garnotii) is a distinctive, small, stout seabird belonging to the unique family Pelecanoididae, a group that exemplifies convergent evolution with auks. Averaging 20-25 cm in length with a wingspan of 30-38 cm and weighing approximately 150-200 grams, it possesses a compact, torpedo-shaped body perfectly suited for its aquatic lifestyle. Its plumage is a striking contrast of uniformly sooty-black upperparts and pristine white underparts, a common patte...
Primarily inhabiting cold, nutrient-rich coastal waters influenced by the Humboldt Current, the Peruvian Diving Petrel breeds on offshore islands and rocky islets. It nests in burrows dug into soft soil or old guano deposits, typically at sea level or slightly inland.
The Peruvian Diving Petrel feeds almost exclusively on small schooling fish, such as anchovies (Engraulis ringens) and sardines, along with various crustaceans, including euphausiids (krill) and copepods. It forages by actively pursuit-diving and swimming underwater to catch prey.
Peruvian Diving Petrels are primarily diurnal foragers at sea but exhibit strict nocturnal behavior at their breeding colonies to evade aerial predators like gulls. They are expert pursuit divers, utilizing their short, stiff wings to 'fly' underwater with powerful strokes, often reaching depths ...
The Peruvian Diving Petrel's breeding range is highly restricted to a series of offshore islands and rocky islets along the coasts of Peru and northern Chile, predominantly within the influence of the cold, productive Humboldt Current. Key breeding colonies in Peru include the Chincha Islands, Sa...
