The Galapagos Penguin is endemic to the equatorial Galápagos Islands of Ecuador and is one of the only tropical penguin species in the world (Bollmer et. al. 2007). The majority of the population breeds on the Fernandina Island, and on the western side of Isabella Island. Nonbreeders also visit the islands of Santiago, Santa Cruz, and Floreana,and islets such as Rábida (Harris 1974, Castro and Phillips 1996, Nims et al. 2007).
