Nazca Boobies also known as Masked Boobies are the biggest of the three booby species that live in the Galapagos, and it differs from its more well-known, colored-footed brethren. Their eggs are normally deposited during August and November on Genovesa Island, however on Española Island, the season stretches from November to February. The Galápagos Nazca Boobies, on the other hand, aren’t very proud of their home. Also, their nests are basically a circle of cleared ground bordered with their own guano. Female Nazca Booby are notorious for murdering their breeding mates. They usually lay two eggs, however they are laid up to nine days apart rather than together. When the second egg hatches, the older female Nazca Booby invariably pushes the new hatchling out of the nest circle, where it is neglected by the parents and dies from malnutrition, cold, or predation.
