Great Frigatebird: Swift Warship of the Skies

Great frigatebirds (Fregata minor) are magnificent, large seabirds known for their distinctive silhouette resembling a pterodactyl in flight. With an impressive wingspan of 205-230 cm, they are unmistakable as they soar gracefully above Cousine Island. These birds primarily feed on fish, especially flying fish, snatching them from the ocean's surface with their large, hooked beaks.

Named for their resemblance to fast warships ("la frégate" in French), frigatebirds rarely land on Cousine but can be observed in small numbers daily. Unlike most seabirds, they lack waterproofing oils and webbed feet, relying on aerial prowess for survival. They snatch prey mid-air or resort to piracy, harassing other seabirds like white-tailed tropicbirds until they drop their catch, a spectacle of speed and agility.

Frigatebirds have long narrow pointed wings and a long narrow deeply forked tail. They have the highest ratio of wing area to body mass and the lowest wing loading of any bird. This has been hypothesized to enable the birds to use marine thermals created by small differences between tropical air and water temperatures.

In Seychelles, they breed exclusively on Aldabra, congregating in colonies, while outside breeding seasons, hundreds roost on Aride Island. Witnessing their aerial acrobatics and predatory tactics is a breathtaking experience, showcasing nature's adaptability and beauty. These birds play a crucial role in the ecosystem dynamics of Seychelles' marine environments, maintaining balance through their foraging habits and unique hunting strategies.
