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.<ref>{{Cite journal |last=van Oordt, F. |last2=Torres-Mura, J.
