About These Birds
King Penguin
The king penguin is the second-largest penguin species, known for its striking orange-gold head markings. Unlike most penguins, king penguins do not build nests — they incubate their single egg on their feet. Their 14-16 month breeding cycle is the longest of any penguin species.
Galapagos Penguin
Galápagos Penguin, 49–53 cm, is the only penguin that breeds north of the equator. Restricted to the Galápagos Islands and dependent on Humboldt Current upwelling. Banded black-and-white with a horseshoe breast band. Piscivore; dives for sardines and mullet. Endangered; highly vulnerable to El Niño events.
