Masked booby 橙嘴蓝脸鲣鸟

Masked booby, a seabird looks like he's wearing a mask, like the superheros.

Adult (yellow peak) and chick look totally different. Our tour guide Washington explained that Mothers lay two eggs, several days apart. Two eggs are laid so that if one gets destroyed or eaten, or the first chick dies soon after hatching, the second egg will be the backup. If both eggs hatch, the elder chick pushes its sibling out of the nest area, leaving it to die of thirst or cold. Talk about survival of the fittest. 

There are 3 kinds of boobies in the Galapagos, red-footed boobies, blue-footed boobies and masked boobies.

橙嘴蓝脸鲣鸟。导游解释妈妈会生两个蛋，各自相差几天。两个蛋是因为假如大蛋被吃了还有小蛋。如果两个蛋都安全无事长大孵化，年长的会把年少的推到巢外直至死亡。这就是自然界的适者生存。
