The square-tailed drongo-cuckoo (Surniculus lugubris) is a species of cuckoo that resembles a black drongo. It is found in Sri Lanka and Southeast Asia and is a summer visitor to the Himalayas from Kashmir to eastern Bangladesh. The calls are series of piercing sharp whistles rising in pitch but shrill and choppily delivered.[2]

Description

It can be easily distinguished by its straight beak and the white barred vent and outer undertail, and the tail only notched with slightly flared tips. In flight a white wing-stripe is visible from below. It is a brood parasite on small babblers. It is not known how or whether the drongo-like appearance benefits this species but it is suspected that it aids in brood-parasitism just as hawk-cuckoos appear like hawks.[3]

Some recent work suggested that the species was conspecific with the fork-tailed drongo-cuckoo and together known as the Asian drongo-cuckoo, but should be split based on call and morphological differences:.[2][4] That treatment is taken here.
