Diving-Petrels
The Magellanic Diving-petrel (Pelecanoides magellani), is a diving-petrel, one of four very similar auk-like small petrels of the southern oceans. This species occurs around the coasts of southernmost South America.
Description
This 20cm bird is the easiest of its family to identify at sea. Like other diving petrels, it is a compact bird, mainly black above and white below, and similar in shape and size to a Little Auk, the resemblances with that unrelated seabird being due to convergence evolution, since both dive for fish.
However, the Magellanic Diving-petrel is the only species with white fringes to the upperpart feathers, and a sharply defined face pattern, so with reasonable views it can be distinguished from its relatives. Males and females look alike, but juveniles lack the white upperpart fringes.
Nesting / Breeding
These birds nest in colonies on islands. One white egg is laid in a burrow in turf or soft soil. They are nocturnal at the breeding colonies.
