Mayotte Drongo Dicrurus waldenii

Bold, glossy-black bird with a very long and deeply forked tail and a red eye. An uncommon species that is confined to the island of Mayotte in the Comoros. Found locally in remnant rainforest, secondary forest, plantations, and mangroves. Perches prominently on open perches, swooping out to catch insects on the wing. Song is a liquid sequence of whistles, creaks, and rasps, often given as a duet.
