It is 16–17 cm long, with upperparts heavily marked with buff and rufous streaks, yellow underparts, and white outertail feathers in flight.
This bird is endangered, with an estimated population of less than 20,000. Its grassland habitat is being replaced by cultivation and woodlots.
The Sharpe's Longclaw is a member of the family Motacillidae, which includes the pipits and wagtails. The species was originally placed with the other longclaws in the genus Macronyx, a treatment still followed by some taxonomists. Most now place the species with the Yellow-breasted Pipit in the separate genus Hemimacronyx. The two species are closely related and form a superspecies. This genus, along with the Golden Pipit in the genus Tmetothylacus and the longclaws form an exclusively African clade within the family, separate from the true pipits in the genus Anthus and the wagtails.
Distribution and habitat
The Sharpe's Longclaw is found in the highlands of west and central Kenya. It has a restricted distribution, occurring on the northern slopes of Mount Kenya, the southern slopes of the Aberdares, on the Gishu, Mau and Kinangop Plateaus around the Rift Valley, and the Kenyan slopes of Mount Elgon (possibly the Ugandan slopes as well).
The natural habitat of the species is open treeless grassland with short and often tussocky grasses. It ranges between 1,850–3,400 m (6,070–11,200 ft) in altitude, although more commonly below 2,800 m (9,200 ft). It occurs at higher altitudes than the Yellow-throated Longclaw, with little overlap between the ranges of the two species. It is generally non-migratory, but will travel short distances when its habitat becomes too dry.
