Behaviour

Frigatebirds cannot land on the water because their feathers are not waterproof. They soar for days on end and chase other birds to steal their catch, or pick fish from the surface in flight.

Why they matter

Frigatebirds have the largest wingspan relative to body weight of any bird, letting them stay aloft for weeks over the ocean. Tracking has shown them sleeping in flight.

Reproduction and lifecycle

Nest — A platform of sticks in mangroves or bushes, in colonies
Eggs — One
Incubation — About 50 to 60 days
Chick — Fed by the female for a year or more
Lifespan — Wild birds over thirty years are recorded

Living around people

  • A frigatebird on the ground or water is in trouble; it needs a rehabilitator.

Misconceptions

  • Frigatebirds can rest on the sea. Their feathers soak through and they cannot take off from water.
