Over a million penguins are gathered at Argentina's Punta Tombo peninsula to migrate, a recent record number according to local officials.

Drawn in by an unusually abundant haul of small fish, the world's largest colony of Magellanic penguins offered up an even larger than normal spectacle.

Around 50 centimetres (20 inches) tall, they have a broad crescent of white feathers that extends from just above each eye to the chin and a small area of pink flesh on the face.

The warm-weather birds breed in large colonies in southern Argentina and Chile and migrate north as far as south-western Brazil between March and September.
