Fork-tailed Drongo-Cuckoo

The fork-tailed drongo-cuckoo resembles the black drongo. It is found mainly in hill forests of peninsular India and Sri Lanka, with a few specimens from the Himalayan foothills. It has glossy black plumage, a straight bill, a forked tail with narrow white bars, a white-barred vent and a white spot on the back of the head. The sexes look alike, and juveniles have white spots on the head, wing and breast (Wikipedia, general species account).

It is a brood parasite on small babblers. Its song is a series of five or six rising whistled pip notes, and it has drongo-like calls. Wikipedia says in Sri Lanka these are similar to those of the Sri Lanka drongo. The 2012 National Red List gives no status under this name.
