The Bridled Tern looks similar to the Sooty Tern but is smaller and grey above rather than pure black. Colonies are smaller, and less densely packed with birds, than those of the Sooty Tern.
The Brown (or Common) Noddy is a medium sized brown seabird with a pale white-grey
Forehead. It is larger than the Lesser Noddy and has a relatively short, stout beak.
Brown Noddies breed from April to September.
The Lesser Noddy is smaller and slimmer then the Brown Noddy and has a very long narrow beak. Its head has a larger pale area then in the Brown Noddy, but the demarcation between light and dark areas is less sharp.
The Fairy (or white) Tern is a beautiful bird seen on all islands in Seychelles, even islands like Mahe where they are killed by introduced rats, cats and Barn Owls. They are usually seen flying around trees in pairs. Fairy Terns use trees for breeding, although they do not build a nest.
