Revision as of 21:03, 27 December 2017
Alternative names: Pale Drongo, Grey Drongo
- Dicrurus leucophaeus
Identification
Size: 25·5–29 cm (10-11½ in). A variable drongo:
- Relatively long and narrow-splayed tail
- Bright red eyes
- Mostly grey body plumage but highly variable from pale grey to almost black. See below for subspecies variations.
- No Rictal spot
Sexes alike, females are slightly smaller than males. Juveniles are browner than adult with some white fringing on belly to undertail-coverts.
Similar species
Especially longicaudatus and nigrescens can be confused with Black Drongo but note brighter red eye, longer tail and the absence of a rictal spot.
Distribution
 |
Breeding in the Himalayas from east Afghanistan east over India, Nepal, Bhutan and China through south-east Asia to Sumatra, Java, Borneo, Bali, Lombok and southwest Philippines. Northern populations winter south to tropical latitudes. |

Taxonomy
Subspecies
There are 14 subspecies[1]:
- D. l. longicaudatus: Eastern Afghanistan to Sikkim; winters to southern India and Sri Lanka (Indian Grey Drongo)
- head and upperparts almost black, long and deeply forked tail
- D. l. hopwoodi: Eastern Himalayas to Burma and southern China; winters to Indochina and eastern India (Assam Grey Drongo)
- unglossed blue-grey, but variable in size and colour
- blue grey above and pale soft ashy grey below, ear-coverts lighter grey
- like mouhoti but smaller and paler
- plumage is black with slight gloss above and darker below. Resembles Black Drongo in shape andd proportions but is never as black.
- pale ashy grey with white cheek patch, including area surrounding eyes.
- resembles leucogenis but white is confined to area surrounding eye.
- D. l. innexus: Hainan (southern China)
- heavier and deeper bill than all other subspecies, lores and ear-coverts more or less whitish
- D. l. stigmatops: Mountains of northern Borneo
- similar to mouhoti but smaller and eye orange-red, white of lores extends around eye
- D. l. batakensis: Northern Sumatra
- similar to phaedrus but a little darker with grey lores
- D. l. phaedrus: Southern Sumatra
- similar to stigmatops but with smaller white loral spot
- D. l. periophthalmicus: Simeulue Island and adjacent Mentawi Islands (off Sumatra)
- pale blue grey like nominate but with large white facial patch
- D. l. siberu: Siberut Island (off Sumatra)
- slightly darker than periophthalmicus
- Ashy grey plumage. dark on throat and underparts with velvety dark frontal band and blackish chin
Two subspecies Dicrurus l. celaenus and Dicrurus l. palawensis are not recognised by all authorities.[1]
Habitat

Hill Station Dalhousie, Himachal Pradesh, India, July 2012
Mangroves, beach scrub, plantation, the forest edges, wooded gardens. Much more confined to forest than Black Drongo. Occurs up to 3000m in the Himalayas.
Behaviour
Diet
Found on exposed perch from which it hawks for flying insects, takes sometimes also small vertebrates. Also dives and climbs while pursuing insects in mid-air.
Breeding
Breeding season May to June in the Himalayas, April to June in China, March to May in Sumatra. A territorial species, acting aggressively towards possible predators.
The nest is a shallow cup made of vegetable fibres like rootlets, grass stems or leaves. It's placed usually high up in a tree. Lays 2 - 4 eggs.
Vocalisation
Distinct series of mewing calls. The different subspecies have different songs.
