Nazca boobies look similar to masked boobies, but have a more salmon-colored bill. They are found primarily in the Galápagos Islands and Malpelo Island, Colombia.

Males and females look very similar, though females are ~15% larger than males.

Nazca boobies nest on the ground, forming small nests of feathers and stones.

This is a juvenile Nazca booby. Before they get their adult feathers, they have a lot of chocolate brown and could be confused with another species. But notice that the chest and belly are all white!
