Great frigatebird (Fregata minor ridgwayi) female harrassing a blue-footed booby (Sula nebouxii excisa, in water) to force it to regurgitate its food. This is known as kleptoparasitism. Boobies and frigatebirds are both seabirds that feed on fish. Boobies do so by diving, but frigatebirds skim the surface to catch their food, or rob other seabirds of their prey. Photographed in the Galapagos Islands.
