Booby

The booby species are part of the family Sulidae. This is a group of seabirds, which also includes the gannets.

The six booby species are in the genus Sula, whilst the three gannets are in Morus, but it is arguable whether all nine species should be considered congeneric.

The boobies are large birds with long pointed wings and long bills. They hunt fish by diving from a height into the sea and pursuing their prey underwater. They have facial air sacs under their skin which cushion the impact with the water.

These are colonial breeders on islands and coasts, which normally lay one or more chalky blue eggs on the ground or sometimes in a tree nest.
