This species breeds in scattered colonies, associated with penguins or petrel colonies. They are highly territorial.
They breed in the Antarctic in November. These birds build their nest by scraping the ground, forming a hole, in the ice-free areas. The clutch size is 2 to 3 eggs. Incubation lasts 28 to 31 days. The chicks are precocious, are born covered with gray-brown down, and leave the nest at two days old. They fly at 36 - 45 days.
