  • Nazca Booby male and female birds preen each other on the Galápagos Islands, Ecuador, South America. The Nazca Booby (which has an orange beak) was formerly regarded as a subspecies of the Masked Booby (which has a yellow beak) but is now recognized as a separate species. Nazca and Masked Booby species differ in size, nesting habits, and mtDNA cytochrome b sequence data.

  • A Nazca Booby (Sula granti) fledges on Española (Hood) Island, the oldest of the Galapagos Islands, which are a province of Ecuador, South America. The Nazca Booby is found in the eastern Pacific Ocean, namely on the Galápagos Islands and Clipperton Island. The Revillagigedo Islands off Baja California possibly constitute its northeasternmost limit of breeding range. It was formerly regarded as a subspecies of the Masked Booby but the Nazca Booby is now recognized as a separate species differing in ecology, morphology, and DNA. The Nazca Booby co-occurs with the Masked Booby on Clipperton Island, where they may rarely hybridize.  Two eggs are laid so that one remains insurance in case the other gets destroyed or eaten, or the chick dies soon after hatching, which often occurs as one chick out-competes the other.

  • A Nazca Booby (Sula granti) colony stains coastal cliffs white with guano on volcanic Española (Hood) Island, the oldest of the Galapagos Islands (formed 3 million years ago), a province of Ecuador, South America. Española is becoming a rocky, barren land with little or no vegetation, with large bays, sand and soft shingle which attracts a healthy number of Galapagos Sea Lions. The English named it Hood Island after Viscount Samuel Hood. Tourists come to see the Waved Albatross and the mating dances of blue-footed boobies. Two spots are especially popular with visitors: Bahía Gardner, which has a lovely beach; and Punta Suárez, of interest because of its varied bird-life. This island has its own species of animals, such as the Española Mockingbird, which has a longer and more curved beak than the one on the central islands; the Española lava lizard; the Marine Iguana, which has red markings on its back; and others. Boobies, Swallow-tailed Gulls and other tropical birds live here. In 1959, Ecuador declared 97% of the land area of the Galápagos Islands to be Galápagos National Park, which UNESCO registered as a World Heritage Site in 1978. Ecuador created the Galápagos Marine Reserve in 1998, which UNESCO appended in 2001.
