The Magellanic penguin (Spheniscus magellanicus) is named in honour of the maritime explorer Ferdinand Magellan, who first recorded it during an expedition in 1519. A medium-sized penguin, this species can be identified by the distinctive white bands which loop over the eye, down the side of the neck and meet at the throat. A thick black band also runs adjacent to the border of the breast and belly, extending down the flanks to the thighs. Aside from these markings, the colouration of the Magellanic penguin is almost entirely uniform black on the upperparts and white on the breast and belly. However, during the breeding season, the adults lose feathers from around the eye and the stout, hooked, grey-black bill, leaving a distinctive patch of pink skin, with an area of dark pigment in the centre. The Magellanic penguin produces a loud, mournful call, similar to that of a donkey bray. This is used most commonly by the males when seeking a mate, but also during other activities such as territorial disputes.
