The Magellanic Penguin is distributed along coastal areas of southern Argentina and Chile. A medium-sized penguin, it resembles the partly sympatric Humboldt Penguin (Spheniscus humboldti) but has a thick black collar, broader white eyebrow, and a smaller area of pink flesh at the bill base. Birds nest on beaches, sandy hills, on grassy slopes, or even in forest. Away from the nest they are largely pelagic, and generally migrate north from April to August. Among the threats to populations of Magellanic Penguin are hunting, egg collecting, guano mining, oil pollution, and commercial fishing.
