Magnificent Frigatebird (The Elegant Thief from Above)

The magnificent frigatebird (Fregata magnificens) is a seabird of the frigatebird family (Fregatidae). The magnificent frigatebird is known by several names including the pirate bird, condor of the oceans, and 'Man-o'-War' bird. With a length of 89–114 cm and a wingspan of 2.17–2.44 m, it is the largest species of frigatebird. Magnificent frigatebirds are found nesting in the Galapagos and the coast of Ecuador down to Mexico and in the Caribbean and Florida. It has occurred as a vagrant as far from its normal range as the Isle of Man, Denmark, Spain, England, Nova Scotia, the Magdalen Islands, and British Columbia.

Frigatebirds are the only seabirds in which the male and female look strikingly different. Females may not have the males' bright red pouch, but they are bigger than males.

The magnificent frigatebird is silent in flight but makes various rattling sounds at its nest. It spends days and nights on the wing, with an average ground speed of 10 km/h, covering up to 223 km before landing. They alternately climb in thermals, to altitudes occasionally as high as 2,500 m, and descend to near the sea surface. This bird makes a shallow platform nest on top of both trees and bushes on islands and cays with mangroves. This nest is constructed out of branches and twigs. The magnificent frigatebird lays a clutch of one clear white egg. After the egg hatches, the male parent will abandon it, with the female staying to provision for the young for almost a year.

Even though magnificent frigatebirds are seabirds, their feathers aren’t waterproof. Because of this, they can’t land on the ocean. If they did, the water would make them very heavy and they wouldn’t be able to take off, which means that they would eventually drown. Their legs and feet are very small, so they can’t paddle well with them, they rarely even walk.

This species feeds mainly on fish, squid, jellyfish, and crustaceans. Individual bird diets vary depending on food availability and preferred hunting techniques.

The Magnificent Frigatebird feeds on fish taken in flight from the ocean's surface (often flying fish). Magnificent frigatebirds practice kleptoparasitism, pecking at other seabirds to force them to disgorge their meals. After forcing the other seabird to regurgitate its meal, the magnificent frigatebird will dive and catch the prey before it hits the surface of the water. Magnificent frigatebirds have a long, thin, hooked beak that is specially designed to help them catch and steal slippery fish. Learning how to chase other birds and steal meals takes practice. Juvenile Frigatebirds practice stealing “food” from one another by playing games with sticks. Young frigatebirds hold sticks in their mouths and chase each other. When one of them drops the stick, the other dives below to retrieve it.

Magnificent Frigatebirds can fly without landing for several days and nights in a row without resting, a trait that earned them the nickname “the condor of the oceans”. Spanish sailors called them “pirate birds” or “Man-o-Wars.” This was because of their habit of stealing food from other birds.

The Magnificent Frigatebird has no known predators. The exception to the rule may be that mammals may sometimes steal their eggs from nests on land. But since Frigatebirds are such careful parents, this does not happen often. The parents monitor their nests around the clock.

The conservation status shows that the species is not under immediate threat, however, some populations globally are being put under pressure due to habitat loss and tourist encroachment on their breeding grounds. Their feeding habits also make them reliant on oceanic predators which bring their food up to the surface. Species such as dolphins and tuna are being put under threat which in turn is a threat to the frigatebirds. They could also be affected by marine plastic pollution.

The magnificent frigatebird is labeled as least concern by the IUCN Red List and as such there are no specific plans in place in Galapagos to protect this species particularly. However, they are protected by the Galapagos National Park.
