The blue-footed booby really does have blue feet. These shore birds are known for their courtship dance, where they seem to show off their feet, do “sky-pointing” with their beaks, and whistle and honk. The male and female blue-footed booby are almost identical—the male is smaller and the iris of the male is smaller.
Blue-footed boobies are also great divers. They can dive into the water from 50 feet above the ocean. Their favorite prey is a small sardine-like fish called salema.
