The fork-tailed drongo-cuckoo (Surniculus dicruroides) is a species of cuckoo that resembles the Black drongo (Dicrurus macrocercus).

[4] Juveniles are distinguishable from adult birds by white spots found across their body (head, wing and breast) and presence of a few brown feather.

Like the hawk-cuckoo which mimics hawks, the fork-tailed drongo-cuckoo imitates the black drongo among other birds that it is a brood parasite too.

They were rearranged as subspecies under Surniculus lugubris as follow: However, in 1919, Baker disagreed and proposed his own taxonomy based on both wing and tail lengths.

[4][7] The fork-tailed drongo-cuckoo was spotted as well in Nepal, East Pakistan and even eastward across southern China, southward Tenasserim, Thailand and up to Sumatra as a migrant.

[7] It is found in a variety of habitats, including woodland, scrub jungle, plantations, orchard, hill forests and sometimes in plains.

[7][8] It is an arboreal bird that keep to the canopy foliage of trees and shrubs but will go to more exposed bare branches when calling (especially during breeding season).

[7] The calls are what helps identify the presence and species of the bird and due to the almost total absence of vocalising during the non-breeding season, they are harder to observe.

[6] It was reported that fork-tailed drongo-cuckoo are brood-parasite on drongos (Dicrurus), forktails (Enicurus), minivets (Pericrocotus) and Black-headed Babbler (Rhopocichla atriceps).

[8][6][11] Fork-tailed drongo-cuckoos are included in Schedule IV of the Indian Wildlife Protection Act of 1972 along with many forest and woodland birds.

[12] While there are no specific studies as to human activities' impact on this species, general trends like climate change or habitat destruction have been found to negatively affect the Avifauna of the Himalaya region.
