Greater Frigatebirds are long-distance fliers and spend most of their life flying over the ocean with a gliding, rarely flapping flight. Unlike other seabirds, the feathers have poor waterproofing and the feet are not webbed.

They cannot land on the sea or dive for food, but must pick prey from the water surface or attack other birds to male them give up their own prey. They build twiggy nests in the tops of mangroves on Aldabra. The males use an inflated bright red throat pouch to display to females; outside the breeding season the pouch is usually invisible. Young birds are dependent on the parents for over a year, so the birds can only breed every couple of years.
Like many seabird species, Great Frigatebirds are long-lived; one survived for 34 years.
