- Sula granti
Identification
Bill pink to orange and feet grey separates from nearest populations of Masked Booby.
Distribution
Galapagos Islands; Isla de la Plata, Ecuador; Peru. Has occurred at least once on southern California.
Taxonomy
It was formerly regarded as a subspecies of the Masked Booby but the Nazca Booby is now recognized as a separate species. They differ in regard to ecological and morphological (Pitman & Jehl 1998) as well as mtDNA cytochrome b sequence data (Friesen et al. 2002). 1
Habitat
Pelagic, except when it comes onshore to breed.
Behaviour
Breeding
2 eggs are laid, several days apart. If both eggs hatch, the elder chick will push its sibling out of the nest area, leaving it to die of thirst or cold. The parent booby will not intervene and the younger chick will inevitably die. 1
