Nazca Booby

The Nazca booby is a large, white seabird with black wings and tail, an orange/pink bill, and a black "mask" on its face, found along the eastern Pacific coast, especially the Galapagos Islands. It's known for its clumsy land movement (hence "booby," from Spanish for clown) and its practice of obligate siblicide, where the older chick pushes the younger out of the nest to ensure its own survival. They feed on fish by plunge-diving and nest on rocky ledges, marking their territory with guano.Read more
