The courtship of the frigate bird is shown in this film. Shots of the male birds on their nests, showing display of their red throat pouches, alternate with those of the females, which fly back and forth above the males. Finally, a female is shown landing next to a male bird and both are seen carrying out bill-shaking. Next are shown young birds and the defence put up by the nesting birds against attacks from the air.
