Frigatebirds mainly catch small fish such as flying fish, particularly the genera Exocoetus and Cypselurus, that are driven to the surface by predators such as tuna and dolphinfish, but they will also eat cephalopods.
The term Frigate Bird itself was used in 1738 by the English naturalist and illustrator Eleazar Albin. Like the genus name, the English term is derived from the French mariners’ name for the bird la frégate—a frigate or fast warship. Christopher Columbus encountered frigatebirds when passing the Cape Verde Islands on his first voyage across the Atlantic in 1492.
Frigate birds can fly for months on end over the open ocean. They are able to engage in both regular sleep and what is called unihemispheric slow-wave sleep, where only half their brain sleeps at a time.
The male has a bright crimson goiter bag. Settled in Central and South America on the shores of the Pacific Ocean, up to Ecuador, on whose postage stamp there is an image of this bird.
The word frigatebird derives from the French mariners’ name for the bird La Frégate – a frigate or fast warship. The etymology of the name was given by French naturalist Jean-Baptiste du Tertre when describing the magnificent frigatebird in 1667.
Scientists have recorded frigatebirds flying at heights of up to 2,500 meters, making them the highest flying of all the bird species. Their giant wings and low muscle mass allow them to glide in the sky for long periods without tiring.
There are five species of Frigate Birds, best known for the red inflatable pouch on the throat of the males. Female Frigate Bird with her chick. Galapagos Islands Frigate Bird. Magnificent Frigate Bird. A Frigate Bird showing off its big red pouch. Galapagos Islands Frigate Birds – mother and baby.
It takes 13 days to build their nest. The male brings her sticks that he has gathered – and stolen from other frigatebirds – to build their nest. The massive wingspan allows them to fly without much effort and make poised aerial movements. The gular sac inflates like a red balloon to attract females.
Only after their current juveniles are ready to fend for themselves will these mothers mate and lay eggs again. One of the most unique magnificent frigate bird facts is that the parental care period of these birds is the longest of all bird species.
The call of the magnificent frigatebird is a repeated rattling noise that sounds much like someone trying to start a stalled car engine.

Introduction: Frigate birds are a family of seabirds known for their remarkable aerial abilities and unique physical characteristics. These birds are found in tropical and subtropical regions around the world, and are known for their long, slender wings and forked tails.
Frigate birds have a number of unique physical characteristics that set them apart from other seabirds.
Frigate birds are about the size of a chicken and have extremely long, slender wings. In general, adult males are all black, and adult females are marked with white below.
Frigate birds fly for months over the ocean and can engage in both regular sleep and use half their brain at a time to sleep during soaring or gliding flight.
In order to glide over longer distances in less cloudy areas, frigate birds regularly climb to very high altitudes by flying inside cumulus clouds, where they can take advantage of strong updrafts.
What is the red thing on a frigate bird?
The males have inflatable red throat pouches called gular pouches. They inflate them to attract females during mating season. The gular sac is the most striking frigatebird feature. Frigate birds fly months over the ocean. They can sleep and use half their brain during soaring or gliding. The frigate bird can stay aloft up to two months without landing. It uses large-scale movements in the air to save energy. By riding favorable winds, it spends more time soaring and less time flapping wings.
Albatrosses are large pelagic birds. They have mammoth wingspans and long, narrow wings. This gives them lift for easy flight. Frigate birds prey upon eggs and chicks of their species, terns, boobies and petrels. Their predators are cats, rats and humans. They may kill chicks and eggs of related species. The frigate bird has to steal food from other birds.
The English name derives from the French La Frégate. Frégate means a frigate or fast warship. The males have bright red throat pouches. They puff them out to attract a mate. Females have white throats and bellies. Frigatebirds ride warm updrafts over tropical oceans. They can signal changing weather patterns. They do not swim. They cannot walk well or take off from flat surfaces.
What happens to frigate birds when it rains?
Their feathers shed rain and trap air against their bodies to help keep them warm. But heavy rains prompt them to seek shelter in bushes and trees. Frigate birds can stay aloft up to two months without landing, a new study finds. This seabird uses large-scale movements in the air to save energy on its flights across the ocean. The Hawaiian word ‘iwa means “thief” in Hawaiian and it reflects the frigatebird’s habit of stealing food from other seabirds.
Birds use a lot of energy keeping warm, so it’s essential they conserve their body heat during heavy rain. So during a light rain birds generally stay out, finding food and living their lives. They stay dry with their water-repelling plumage just as you might with a good rain suit. Some birds can fly above clouds, including frigate birds and eagles. A bird flaps its wings up and down to move forward and achieve lift.
By flying into a cloud. Or they fly over a fish-feeding frenzy on the ocean surface and scoop up small fish that leap out of the water to escape larger fish. The males have inflatable red-coloured throat pouches called gular pouches, which they inflate to attract females during the mating season. When this happens, they will fly downwind until they reach the calm center of the storm. Oceanic birds, such as Magnificent Frigate Birds and Pelicans, can easily adapt to massive hurricanes and storms.
The inner layer of feathers is also very fluffy, which helps to trap air and insulation against the cold weather. Birds can also huddle together to stay warm in the rain. They can rest in birds’ nests or under trees, which provide them protection while also keeping their feathers dry. When frigate birds need a drink, they have developed a unique strategy for staying dry. They can scoop up water in their feathers and then let it evaporate away. Their feathers aren’t waterproof. They are excellent swimmers, and they can spend long periods of time in the water, but they are not waterproof like some other bird species, such as the grebes. Frigatebirds have to find ways to stay aloft because they can’t land on the water. Since their feathers aren’t waterproof, the birds would drown in short order. They feed by harassing other birds in flight until they regurgitate whatever fish they’ve eaten and the frigatebird takes it.
Why do frigate birds sleep while flying?
Frigatebirds sleep while flying to restore brain function. As they catch an updraft and soar, they may sleep for 12 minutes. Their inability to stop on water to rest made scientists suspect they sleep while flying. Niels Rattenborg studied their sleep patterns. He found it easy to capture 15 birds in the Galapagos Islands to implant devices to measure brain activity and flight. The goal was to determine how long they sleep and function with little sleep.
The researchers tracked the birds on Genovesa Island. Most birds sleep half their brain, maintaining some alertness. But frigatebirds also fall into deep REM sleep for short times with no effect on flight. They sleep one hemisphere at a time, keeping one eye open.
Frigatebirds range along tropical coasts and islands. They nest on coral reefs and in trees. They forage over oceans and coasts. Their other name is Fregata magnificens.
The researchers tracked movements of 24 adults and 25 juveniles for four years with transmitters. The birds left Europa from June to September, caught trade winds to the equator and turned east to Indonesia. Frigatebirds ride thermals without flapping much. But equatorial skies have little wind, which challenged pre-industrial sailors.
One frigatebird stayed aloft two months. They can fly over 4000 meters high. No other bird stays aloft as long. Hummingbirds can rotate wings to fly backwards. Frigatebirds fly so high to save energy by flapping less and gliding more. Albatrosses are the largest marine birds. Mystery remains why frigatebirds can fly so long without sleep while other animals require sleep to live. Modern technology uncovers birds are more wonderful than we knew.
