This is a migratory species arriving on the Falklands in September for breeding and departing in mid-April. It differs from the Humboldt Penguin (S. humboldti) of Western South America in that Magellanic has double dark breast bands, wider white eyebrow stripe, and a thinner bill with less pink at its base. The pink color appears during the breeding season when molt reveals bare pink skin. Juveniles fledge in February so this burrow was not in use when I took these photos. Population declines in Argentina have caused concern and the species is listed as "near threatened" by IUCN. The main threats are oil pollution, commercial fishing, and climate change.
