Field Identification

13 cm. Small slender-billed weaver, dark above and white below, more like a flycatcher (Muscicapidae) than like a typical weaver. Male has forehead, crown and nape blackish-brown, extending on side of head to level of bill; mantle and back blackish-brown with yellow feather tips in mid-line, rump yellow; upperwing and tail dark brown, remiges with white edges, greater wing-coverts with broad white tips and lesser coverts with narrow white tips (forming conspicuous wing­bars); chin and throat white, underparts white with yellow wash; iris red; bill black; legs brown. Female resembles male, but tips of mantle feathers whiter, much less yellow wash on underparts. Juvenile has crown dull olive-grey, cheek and narrow superciliary stripe white, upper mandible greenish-grey, lower mandible pinkish.

Systematics History

Previously placed in monotypic genus Notiospiza on account of singularities in morphology and plumage. Monotypic.

Subspecies

Monotypic.

Distribution

WC Angola, SE DRCongo and N Zambia.

Habitat

Miombo (Brachystegia) woodland; also enters Cryptosepalum forest. At 100–1600 m.

Movement

Apparently resident. In Zambia, recorded throughout year at same localities.

Diet and Foraging

Insectivorous; stomach contents included mantid (Mantodea), beetles (Coleoptera) and chironomid larvae (Diptera). Forages in tree canopy. Gleans on trunk and main branches, moving like a nuthatch (Sittidae), also probes in Usnea lichen. Often in pairs or family parties. Frequently joins mixed-species flocks with Dark-eyed Black (Melaniparus leucomelas), Miombo (M. griseiventris) and Rufous-bellied Tits (M. rufiventris), hyliotas (Hyliota) and eremomelas (Eremomela); sometimes with Anaplectes rubriceps.

Sounds and Vocal Behavior

Song composed of several fast, tuneful notes in crescendo, leading up to loud swizzle; sometimes followed by more tuneful notes in decrescendo. Squeaky contact call of pure descending note followed by several lower-pitched notes, "tyoo-vo-vo-vo-vo", also higher-pitched "tzee-zi-zee-zi-zee-zi".

Breeding

Breeds Aug–Nov in Zambia. Monogamous. Solitary nester. Nest built by both members of pair, a ball of Usnea lichen with framework of fine grass stems and leaf midribs, entrance funnel extending 3–20 cm below nest-chamber, suspended c. 10 m above ground below lichen-covered branches in Julbernardia globiflora or Brachystegia boehmii tree; one nest had apparent false entrance to empty chamber. Clutch 2–3 eggs, turquoise-blue, flecked and clouded with darker markings, mostly at thicker end, 20·5 x 15·3 mm (Zambia). No other information.
Not globally threatened. Poorly known species. Reported as uncommon within its relatively limited range. Occurs in some protected areas in Zambia.
