15 cm; 20 g. Smallish, dark lark with heavy, pinkish bill , distinctive black facial markings . Nominate race has black mask from base of bill to area around eye and extending down into broad malar band, latter with white central patch, and accentuated by pale anterior ear-coverts; crown and upperparts grey-brown with blackish central feather streaks, rump plainer, upperwing-coverts and tertials dark brown with broad cinnamon margins; flight-feathers and tail brown, outer rectrices broadly edged buff-cinnamon; throat white, breast greyish-brown, shading to rufous-brown on belly, buff undertail-coverts; eyes brown; bill pale pink or yellowish-horn; legs pale pink. Sexes alike. Juvenile undescribed. Races vary in coloration: yavelloensis is darker and greyer above, dark greyish breast contrasting more with rufous belly; <em>mcchesneyi</em> has browner upperparts darker than nominate; intensa is rich brown above, darker below, belly deeper reddish.

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

Arid plains on black or red lava and black-cotton soils. Prefers areas with little shrub or grass cover, but apparently avoids road edges. At 400–1600 m.

Movement

Poorly known; presumably resident and locally nomadic.

Diet and Foraging

Grass seeds, bulbs and corms; also some insects, including grasshopper (Acrididae) egg cases. Feeds on the ground; presumably used heavy bill to dig for bulbs and corms. Often stands erect on rocks, possibly to reduce heat stress.

Sounds and Vocal Behavior

Call, given on ground or in flight, described as rolling “chew-chi chew, chew”, “tew tew tutew tew” or shorter “chew” or “chew-chew”; also high-pitched “treeeee” and repeated “tee tee tee”.

Breeding

One specimen with well-developed egg in oviduct in Jul. No other information.

Not globally threatened. Locally common. Poorly known species; fieldwork required in order to ascertain details of breeding biology and ecology. Occurs in several protected areas , including Shaba Game Reserve, in C Kenya.
