[edit] Identification

Length 9-10cm, mass 9g.

Adult: Head, nape, throat, upper breast and tail black. Mantle, back and lesser wing coverts are chestnut or black. The rump, flanks and flight-feather panel on folded wings are barred black and white and the lower breast, belly and undertail coverts are white. Bill blue-grey, eyes brown and legs and feet dark grey.

Immature (S. b. nigriceps): Birds moult gradually to adult plumage; the head and throat are mottled brown and black and are the last parts to gain adult colouring.

[edit] Distribution

Most of Africa south of the Sahara, except the easternmost parts. It is also found as an escapee all the way in Singapore. A bird was observed building a nest on a tree on May 17 in Singapore but breeding has yet to be confirmed.

[edit] Taxonomy

Black-and-white Mannikin has five subspecies:1

  • L. b. bicolor
  • L. b. woltersi
  • Mantle, back and lesser wing coverts are black
  • South-eastern Zaire and north-western Zambia
  • L. b. poensis
  • L. b. nigriceps
  • L. b. minor
  • Mantle, back and lesser wing coverts are chestnut
  • Southern Somalia
  • Sometimes lumped with L. b. nigriceps

Some authorities separate nigriceps and minor as a separate species, Red-backed Mannikin L. nigriceps.2

Black-and-white Mannikin is sometimes placed in the genus Spermestes.

[edit] Habitat

Moist savanna and woodland, lowland moist forest, forest edges, parks, gardens.

[edit] Behaviour

Locally common; generally in small flocks. Forages both on the ground and from seed heads of standing grass.

[edit] Diet

Eats seeds of many species of grass; also small insects. Visits seed feeders, especially when natural sources of grass seed are limited (winter and spring in southern Africa). Also eats petals, nectar and filamentous algae from pools.

[edit] Breeding

The nest is an oval ball, generally of grass, but old-man's-beard (lichen of the genus Usnea) and wild asparagus stems are also used. Two to seven eggs are laid (October to May in southern Africa).

[edit] Vocalisation

The song is a short series of contact notes run together. Contact calls are soft kip (given with bill closed) and a short piping or whistling seeet seeet, usually given in flight; alarm call is a short harsh note.
