Коморский дронго Dicrurus fuscipennis

Bold, glossy-black fork-tailed bird with a red eye. A rare endangered species that is confined to the island of Grand Comoro. Found locally at lower elevations in plantations, secondary forest, and scrub. Perches prominently on open perches, swooping out to catch insects on the wing. Song is a repeated sequence of whistles, creaks, and rasps. Somewhat similar to Grand Comoro Bulbul, but darker, with a forked tail, and without an orange bill.
