ナスカカツオドリ Sula granti

Large seabird, very similar to Masked Booby. Long and pointy on all ends: wings, tail, and bill. Adults mostly gleaming white with black flight feathers and face; note pinkish-orange (not yellow) bill to help separate from adult Masked. Young birds darker overall with brown head contrasting with white belly and dirty brown markings on underwings; very similar to young Masked or even adult Brown Booby. Found in the Pacific Ocean from Mexico to Peru where it feeds on fish; breeds on rocky islands, especially the Galapagos.
