Masked Booby Sula dactylatra

  • © Tim Lenz

The Masked Booby is a large, streamlined seabird of tropical seas.  It has a pantropical distribution, but in the neotropics it is found both along the Pacific Coast and in Caribbean Sea, breeding primarily on offshore islands.  Though it is closely related to the Nazca Booby and Brown Booby, it can generally be identified by its stout, horn-colored bill with dark facial skin, overall white body plumage, and black flight feathers and tail.  At sea, Masked Boobies can be seen folding their wings into their bodies and plunge-diving into the ocean to catch small fish.
