aldabradrongo Dicrurus aldabranus

Bold, black fork-tailed bird with a red eye. There is sometimes but not always a tuft of long feathers above the bill. Juveniles have an unusual pale-gray plumage, but still show the forked tail. Found in all habitats with bushes and trees on the remote Seychelles island of Aldabra, including forest, mangroves, and thick scrub. Perches prominently in the open, swooping out to catch insects on the wing. Often follows Madagascar Coucals and Aldabra Giant Tortoises, feeding on insects that they disturb. Song is a repeated sequence of whistles, creaks, and rasps.
