Field Identification

13 cm; 12–14 g. A rather nondescript, prinia-like warbler with conspicuous pale eye, strongly graduated tail. Has crown and upperparts fairly pale grey, narrowly streaked blackish on crown, washed buff on rump; flight-feathers and greater upperwing-coverts dark grey-brown with slightly paler margins, tail grey, rectrices with narrow whitish margins when fresh; face, throat and breast pale grey, merging into pale buff on belly and flanks, central belly whitish; iris creamy, sometimes speckled brown; bill black; legs pinkish. Sexes alike. Juvenile undescribed.

Systematics History

See S. leucopogon. Monotypic.

Subspecies

Monotypic.

Distribution

Locally in highlands of Guinea (Dalaba, Pic de Fon, Pic de Tibé, Mt Tétini), NE Sierra Leone (Loma Mts, Tingi Hills), N Liberia (Mt Nimba, Kitoma Mts, Bele) and W Ivory Coast (Man, Sipilou and possibly Mt Nimba).

Habitat

Forest edge, riparian scrub and thickets along mountain streams. Occurs at 600–1600 m, mainly above 1000 m, in areas with annual rainfall above 2000 mm.

Movement

Little known; presumably resident.

Diet and Foraging

Diet insects, including beetles (Coleoptera). Forages in low and middle strata along forest edge, often in small groups. Unlike Prinia species, does not cock tail while foraging.

Sounds and Vocal Behavior

Individuals call singly, partners duet and groups chorus together; repetitive series of high-pitched “tsip-tsip-tsip” and slower, nasal “bur-bur-bur” notes, presumably by different sexes.

Breeding

Little known. Food-carrying adult and birds with enlarged gonads and brood patches in Sept–Oct; presumed breeding adult had tail bent to one side, suggesting enclosed nest. No other information.

ENDANGERED. Restricted-range species: present in Upper Guinea Forests EBA. Believed to be scarce and uncommon, with estimated population in the range 1000–2500 mature individuals, with fewer than 250 per subpopulation BirdLife International (2018) Species factsheet: Schistolais leontica. Downloaded from http://www.birdlife.org on 16/01/2018. . Recent discoveries in W Guinea (near Dalaba), W of its main range, suggest that this species may be more widespread and more numerous than was originally thought. However, a total of just 26 pairs/family groups estimated at Pic de Fon in 2009 BirdLife International (2018) Species factsheet: Schistolais leontica. Downloaded from http://www.birdlife.org on 16/01/2018. , while only 5 pairs/small family groups were found on surveys of E Nimba, Liberia in 2011, suggesting that the subpopulation there may comprise little more than mature individuals BirdLife International (2018) Species factsheet: Schistolais leontica. Downloaded from http://www.birdlife.org on 16/01/2018. . The most severe and urgent threat is iron ore mining, with the two sites that retain the largest area of remaining habitat (Pic de Fon and Mt Nimba) under imminent threat BirdLife International (2018) Species factsheet: Schistolais leontica. Downloaded from http://www.birdlife.org on 16/01/2018. . Shifting cultivation, small scale logging and overgrazing by cattle are further threats.
