Revision as of 03:18, 1 April 2020
Alternative name: African Drongo
- Dicrurus adsimilis
Identification
23–26 cm (9-10 in)
- Glossy black overall plumage
- Wings duller
- Large head
- Forked tail
- Heavy black bill
- Red eye
- Short legs
Female similar but duller
Variations
Formerly the population in Tanzania and much of Kenya were assigned to the nominate race, D. a. adsimilis now placed within the range of D. a. fugax. It is described as smaller with a more deeply forked tail.
Similar species
Differs from similar Velvet-mantled Drongo in having tail shorter than wing, a less deep tail fork, slightly less gloss and no pale rictal spot. Square-tailed Drongo and Shining Drongo are smaller and have a less forked tail.
Distribution
The Fork-tailed Drongo is a common and widespread resident breeder in Africa south of the Sahara, being most common in Botswana, Zimbabwe and the northern parts of South Africa and Mozambique.
Taxonomy
Forms a superspecies with Black Drongo of Asia and was formerly regarded as conspecific. They were split in 2007 by Pasquet et al.[5]The combined pre-split species was known as "Common Drongo" or just "Drongo." Former subspecies D. a. divaricatus now recognized as a separate species, the Glossy-backed Drongo.
Subspecies
Four subspecies recognized[1]:
- D. a. apivorus:
- Southeast Gabon and adjacent Congo, patchily in Democratic Republic of the Congo, Angola, Zambia, Namibia, Botswana and northern South Africa (northern Northern Cape to Limpopo)
- D. a. jubaensis: (formerly considered a junior synonym of D. a. divaricatus)
- Ethiopia, Eritrea, and Somalia
- D. a. fugax:
- D. a. adsimilis:
- Eastern and southern South Africa (southwestern Western Cape north to southern Mpumalanga and KwaZulu-Natal), Lesotho, and western Swaziland
Former subspecies D. a. divaricatus now recognized as a separate species Glossy-backed Drongo.[6]
Habitat
Woodlands including riverine woodlands, moist and arid savanna, forest edges and grassland or fynbos with available perches, plantations of alien trees, gardens, farmyards and town parks.
Behaviour
Actions
Sits very upright whilst perched prominently, like a shrike. An aggressive bird, which will attack much larger species, including birds of prey, snakes and humans, if their nest or young are threatened.
Diet
Their prey is taken aerially and on the ground, and includes flying insects, moths and bees; most often they will sit on a branch and sally out from there, but it may also be sitting on the ground. They are often seen taking prey disturbed by large animals or bush fires. They also often steal food from other birds, and have been known to steal food from suricates (Meerkats) and Southern Pied Babblers by sounding false alarms.
Breeding
Monogamous, solitary nester building thin-walled, strongly woven cup nests in high tree-forks. Two to five eggs of highly varying colour.
Vocalisation
The call is a metallic strink-strink. They are also excellent mimics.
Movements
Resident; possibly some short-distance movements in southern part of range.
