MASKED BOOBY Sula dactylatra


Masked Booby is a sort of intermediate between Gannets and Boobies in terms of plumage, but the black face mask is readily apparent, contrasting with the yellow bill. Juvenile and immature Masked Boobies could be confused with Brown Booby, but are usually paler with more mottled upperparts and a white cervical collar (where Brown is all dark).
