Blue-footed booby (adult & chicks)

Description:

The Blue-footed Booby usually lays one to three eggs at a time. The species practices asynchronous hatching, which means that eggs that are laid first are hatched before the consequent eggs, resulting in a growth inequality and size disparity between siblings. This could result in siblicide in times of food scarcity, & the gradual starvation of the younger chick at other times as the parents respond the older's constant demands for food.

Habitat:

Espaniola, Galapagos
