Field Identification

12–13 cm; male 8–13 g, female 7–11 g. A nondescript dark grey forest apalis with a fairly long tail. Nominate race has grey-brown crown, contrasting slightly with sooty-grey upperparts and upperwing; tail dark grey, white tips on T2 and T3, outer three rectrices white; cheek and ear-coverts often a little darker than crown and back, giving slightly masked appearance; whitish below, flanks washed pale grey; iris reddish-brown; bill black; legs pink. Distinguished from A. alticola by greyer head, white outer tail feathers (not grey with white tips). Sexes alike. Juvenile is washed olive above, throat and breast pale yellow. Race sclateri lacks brown wash on crown, has more uniform face and buffier underparts; <em>grandis</em> is larger than nominate.

Systematics History

Editor's Note: This article requires further editing work to merge existing content into the appropriate Subspecies sections. Please bear with us while this update takes place.

Often treated as conspecific with A. alticola (1, 2) and preliminary genetic data appear to support such treatment (3); reports of sympatry in S Kenya and N Tanzania potentially erroneous, but might involve an undescribed taxon in this group (4); further research required. Proposed race funebris (SE Nigeria, SW Cameroon highlands, NE Gabon) described on basis of a worn specimen; treated as a synonym of nominate, despite large gap in distribution. Birds on Mt Cameroon, included in sclateri, are somewhat intermediate between that race and nominate. Three subspecies recognized.

Distribution

Editor's Note: Additional distribution information for this taxon can be found in the 'Subspecies' article above. In the future we will develop a range-wide distribution article.

Habitat

Montane forest and secondary growth; also adjacent thickets and well-developed woodland, including acacia trees (Acacia) at forest edge in S Sudan. At 850–2900 m in Cameroon, mainly above 1000 m in Gabon and Angola; 1200–2400 m in Albertine Rift, 1700–3000 m in Kenya Highlands, and above 1800 m in S Sudan.

Movement

Presumably mostly resident.

Diet and Foraging

Diet mainly insects and other invertebrates, including beetles (Coleoptera), caterpillars (Lepidoptera) and spiders (Araneae). Occurs in pairs or in groups of up to eight individuals, rarely singly; frequently joins mixed-species parties, including those with A. porphyrolaema and A. argentea. Forages mainly in canopy and subcanopy, but descends close to ground at forest edge and in creeper tangles. Gleans items from leaves and small branches; also hawks insects in flight.

Sounds and Vocal Behavior

Calls  mainly in early morning and late afternoon, but also after rain. Male song  , from prominent perch (usually at top of tree), a dry, monotonous repetition of “chip”, “krrip” or “pitch-ew”, varying in pitch and pace, sometimes a fast, high-pitched trill; female may accompany male with high-pitched calls. Countersings with A. jacksoni. Both sexes snap wings and bill when excited.

Breeding

Breeds during Nov–Mar dry season in SW Cameroon, Jan–Jul in E Africa, and Sept–Jan in Rwanda and Angola. Probably monogamous; solitary, territorial, chases off A. argentea in Nyungwe Forest (Rwanda). Nest built by both sexes, in c. 2 weeks, a bulky oval with side entrance at top, made mainly from Usnea lichens and mosses, bound with spider webs and plant fibres, lined with feathers and plant down, placed usually 6–10 m up in subcanopy or in forest-edge tree, typically near end of branch, with entrance facing outwards; favours sites with abundant lichens; may use same site in successive years. Clutch 3 eggs; incubation almost entirely by female, period 13–14 days; chicks fed by both sexes, mainly in morning and late afternoon (food delivered every 5 minutes), chick faeces initially swallowed, later carried away by adults, nestling period 15–16 days. Nests frequently preyed on; only three of eight nesting attempts successful in one study; regularly mobs predators such as snakes.
Not globally threatened. Common through much of its range. The most abundant apalis in SW Cameroon. Occurs at density of 2–3 pairs/ha in Nyungwe Forest, in Rwanda.
