Masked Booby - Sula dactylatra
It has a white body; brownish-black wings and tail; and a long, pointed orange-yellow bill. It has a black mask around its eyes and bill and large, gray webbed feet.
The masked booby breeds in the Caribbean and across the Pacific Ocean to Hawaii, Australia, and Indonesia. Occasionally, it is found in the Gulf states of Louisiana, Texas, and Florida. It winters in open ocean waters.
The masked booby plunges head first into the ocean to catch flying fish and squid.
The masked booby makes its nest in a shallow depression on the ground. The female usually lays one to two eggs. Both parents incubate the eggs. They use their webbed feet to warm the eggs. The masked booby nests in large colonies.
If masked boobies lay two eggs, usually only one hatches. In fact, masked booby eggs hatch only about 60 percent of the time. The second egg may be an "insurance egg" that raises the chances of at least one egg hatching. If the second egg hatches, the older chick often forces the younger chick out of the nest where it more than likely will die from heat or predators. The parents may even help the older chick by moving out of its way while it forces the younger chick out. While this may seem cruel, forcing the younger chick out increases the chances of survival for the older chick and in the long run the masked booby species because the parents are better able to care for one chick at a time.
