The Humboldt Penguinn is a medium-sized penguin that breeds coastally in Peru and Chile and feeds offshore in the Humboldt Current. It overlaps the similar Magellanic Penguin (Spheniscus magellanicus) in central Chile, but can be distinguished by its narrower white supercilium and larger fleshy margins at the base of its bill. Pairs nest in small colonies on islands or rocky coasts. Humboldt Penguins feed mostly on schooling fish and squid. This species is threatened by various activities, including commercial fishing, hunting, and the live animal trade.
