It only overlaps with the Peruvian diving-petrel, P. garnotii, but the two are distinguishable by the visible white crescent of the Magellanic vs. the nearly all-black head of the Peruvian. Distribution and habitat The Magellanic diving-petrel breeds on vegetated slopes on coastal and nearshore islands, typically in fjords and channels, in southern Chile, Argentina, and Tierra del Fuego and forages in offshore and inshore waters in the area. Behavior and ecology Feeding Being the most elusive of the Pelecanoides species, not much is known about the ecology of the Magellanic diving-petrel. Like all diving-petrel species, P. magellani is a strong swimmer capable of performing dives of over 10 ft to pursue prey, staying submerged anywhere from 10 seconds to potentially over a minute. The birds usual dive from the surface, though are capable of dropping a few feet from the air into the ocean. They move through the water by propelling themselves with their wings and steering with their tails and feet. The prey of P. magellani is shown to consist of small crustaceans, aquatic invertebrates like copepods, amphipods, and plankton, and perhaps small fish could be in their diet as well. They likely carry food back to their chicks via their gular pouches then regurgitating food through them. Breeding Breeding habits of the Magellanic diving-petrel are little known. It is known that eggs are laid from November to December, and fledglings have been spotted in March. Like its congeners, P. magellani nests in burrows in dense colonies on coastal islands. They lay one egg and are most likely monogamous like other Procellariiformes. Both parents take shifts between incubation and going out to sea to feed during the incubation period, and both take turns feeding their chick, which will reach sexual maturity anywhere from 2-3 years of age. After raising their offspring, the adults go into what is called post-nuptial moult, where they shed old feathers to grow fresh feathers, most notably their flight feathers. During this time, for all Pelecanoides species, they become flightless until their feathers have been fully replaced. Status and conservation The Magellanic diving-petrel is considered as Least Concern on the IUCN Red List. Their population is estimated anywhere from 6,700-330,000 individuals; they are under no immediate threat, but are presumed to be affected by invasive species (i.e. rats or mice) and human activity, namely periodic guano harvests, could be a threat. However, the species is
