Frigate bird Large bird
The Frigate bird is one of the largest birds flying around St Maarten. An adult male has a wingspan of nearly two meters! They have a easy recognizable silhouette in the sky, due to their forked tail. The male is distinguished by a red throat pouch, which swells enormously in the mating season. The frigate bird can endlessly float through the air without a wing beat. They are true air acrobats and often chase other seabirds with less stamina until they release their fish.

The moment they have discovered a prey to steal from, the wings are folded up and they shoot in a quick swoop down. when they are approaching the surface to within a few centimeters, the wings unfold and they float back up again is, of course, with the loot in their beak. They will never land on the water, because they are not able to then take off again. Their plumage is in fact not waterproof, the frigate bird can therefore not swim and dive.
