The ʻā, or masked booby, is the largest of the boobies. They typically nest on the ground, using pebbles and other debris. Like the other booby species, a large portion of a Masked Booby’s diet is flying fish. They are mostly white with a black tail and wing edge. Their bill and eyes are yellow, with a dark mask and legs.
