Adult males have a red inflatable throat pouch. Females have white breasts and on average are larger than males. Juveniles have rusty to white heads and throats. Great Frigatebirds range widely within tropical Indian and Pacific Oceans. Feeding Habits Lacking the ability to take off from water, frigatebirds snatch prey from the ocean surface using their long, hooked bills.
Prey primarily consist of fish and squid.
Juveniles and adults often obtain food by piracy from boobies, tropicbirds, and shearwaters. Frigatebirds often supplement their diet by this type of harassment. Breeding Frigatebirds begin to breed after nine years. Females do not breed every year because it takes a year and a half to raise a chick. Fidelity to nest sites and mates is low.
