A booby is a seabird in the genus Sula, part of the family Sulidae. Boobies are closely related to the gannets (Morus), which were formerly included in Sula.
Boobies hunt fish by diving from a height into the sea and pursuing their prey underwater. Facial air sacs under their skin cushion the impact with the water. Boobies are colonial breeders on islands and coasts. They normally lay one or more chalky-blue eggs
on the ground or sometimes in a tree nest. Selective pressures, likely through
competition for resource, have shaped the ecomorphology and foraging behaviours of the six species of boobies in
the Pacific.
Species include Blue-Footed Booby, Red-Footed Booby, Brown Booby, Peruvian Booby, Masked Booby and the Nazca Booby.
