The Blue-footed Booby (*Sula nebouxii*) is a large seabird of the eastern Pacific Ocean, best known for its bright blue feet and courtship displays. It breeds on islands and coastal areas from the Gulf of California south to Peru, with major populations in the Galápagos Islands. The species is listed as Least Concern.

Description

Blue-footed Boobies are large seabirds with brown upperparts, white underparts, and striking blue feet. Their name is derived from the Spanish word 'bobo', meaning foolish or silly, a reference to their tame behavior around people.

Distribution and habitat

The species occurs along the eastern Pacific coast, from the Gulf of California and western Central America to Peru, as well as on oceanic islands such as the Galápagos. It is a seabird that spends much of its life near the coast or at sea.

Diet and feeding

Blue-footed Boobies are specialized fish-eaters. They hunt by diving from the air or from the water’s surface to catch small schooling fish.

Breeding and courtship

During breeding, males perform an elaborate dance that highlights their feet. Females tend to choose males with brighter blue feet, which are considered an indicator of condition.

Key facts

  • The species is identified by its vivid blue webbed feet, a trait used in courtship.
  • It inhabits marine and island environments in the eastern Pacific.
  • Blue-footed Boobies feed mainly on small fish and use plunge-diving to catch prey.
  • Males perform courtship displays that showcase their feet, and females prefer brighter blue feet.
