Blue-footed Booby

The blue-footed booby is a marine bird native to subtropical and tropical regions of the eastern Pacific Ocean. It is one of six species of the genus Sula – known as boobies. It is easily recognizable by its distinctive bright blue feet, which is a sexually selected trait and a product of their diet. Males display their feet in an elaborate mating ritual by lifting them up and down while strutting before the female. Females are slightly larger than males and can measure up to 90 cm (35 in) long with a wingspan up to 1.5 m (5 ft).
