The Nazca Booby (Sula granti) is a beautiful bird with a not-so-beautiful start at life. Raised near the eastern Pacific Ocean, females will lay two eggs. The eldest has a bit of a selfish demeanor, and will wait for it’s younger sibling to hatch. Upon hatching, the elder chick will shove it’s younger sibling out of the nest. The worst part is the mother won’t intervene, and instead watches it’s young plummet to death, or die due to the harsh conditions and lack of food. Although scientists are unsure as to why a mother would practically sentence it’s offspring to an inevitable death, the best guess is they’re a backup in case one egg is broken or eaten.
