Sula dactylatra (Masked Booby)

Language: Spanish

Wikipedia Abstract

("Parasula" redirects here. The fossil genus established by C.J.O. Harrison is properly called Empheresula.) The masked booby (Sula dactylatra) is a large seabird of the booby family, Sulidae. This species breeds on islands in tropical oceans, except in the eastern Atlantic; in the eastern Pacific it is replaced by the Nazca booby, Sula granti, which was formerly regarded as a subspecies of masked booby. It is also called the masked gannet or the blue-faced booby.
