Sharpe's Longclaw

Sharpe's longclaw (Macronyx sharpei) is a passerine bird in the longclaw family Motacillidae, which also includes the pipits and wagtails. It is endemic to Kenya.

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 common name and Latin binomial name commemorate the British zoologist Richard Bowdler Sharpe.

Taxonomy

Kinangop Plateau - Kenya

Sharpe's longclaw was described by the English ornithologist Frederick John Jackson in 1904 from specimens collected in the Mau Plateau area of Kenya. He coined the binomial name Macronyx sharpei. Both the common name and the specific epithet honour the English ornithologist and museum curator Richard Bowdler Sharpe. [2]

The Sharpe's longclaw is a member of the family Motacillidae, which includes the pipits and wagtails. Some ornithologists 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. [3]

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). [3]

The natural habitat of the species is open treeless grassland with short and often tussocky grasses. It ranges between 1,850 and 3,400 m (6,070–11,150 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. [3]

Behaviour

Diet and feeding

The Sharpe's longclaw feeds on insects, particularly grasshoppers and beetles. Other invertebrates are taken as well. Within its range it has a higher feeding rate in grasslands with tussocks. The species forages alone or in pairs, sometimes in small family groups. [3]

Breeding

The Sharpe's longclaw is a monogamous and solitary breeder that defends a territory. The breeding season is during or after the rains, from March to June, September to October and in December. The species has a brief aerial breeding display, where the bird flies up and then drops, singing rapidly as it drops. The nest is a well-made cup of dried grass lined with roots and placed near the ground at the base of a grass tussock or under a shrub or plant. Between two and three eggs are laid. [3]

<span class="mw-page-title-main">Wagtail</span> Genus of birds

Wagtails are a group of passerine birds that form the genus Motacilla in the family Motacillidae. The common name and genus name are derived from their characteristic tail pumping behaviour. Together with the pipits and longclaws they form the family Motacillidae.

<span class="mw-page-title-main">Pipit</span> Genus of birds

The pipits are a cosmopolitan genus, Anthus, of small passerine birds with medium to long tails. Along with the wagtails and longclaws, the pipits make up the family Motacillidae. The genus is widespread, occurring across most of the world, except the driest deserts, rainforest and the mainland of Antarctica.

<span class="mw-page-title-main">Motacillidae</span> Family of birds

The wagtails, longclaws, and pipits are a family, Motacillidae, of small passerine birds with medium to long tails. Around 70 species occur in five genera. The longclaws are entirely restricted to the Afrotropics, and the wagtails are predominantly found in Europe, Africa, and Asia, with two species migrating and breeding in Alaska. The pipits have the most cosmopolitan distribution, being found mostly in the Old World, but occurring also in the Americas and oceanic islands such as New Zealand and the Falklands. Two African species, the yellow-breasted pipit and Sharpe's longclaw, are sometimes placed in a separate seventh genus, Hemimacronyx, which is closely related to the longclaws.

<span class="mw-page-title-main">European rock pipit</span> Small passerine bird that breeds in western Europe

The European rock pipit, or simply rock pipit, is a species of small passerine bird that breeds in western Europe on rocky coasts. It has streaked greyish-brown upperparts and buff underparts, and is similar in appearance to other European pipits. There are three subspecies, of which only the Fennoscandian one is migratory, wintering in shoreline habitats further south in Europe. The European rock pipit is territorial at least in the breeding season, and year-round where it is resident. Males will sometimes enter an adjacent territory to assist the resident in repelling an intruder, behaviour only otherwise known from the African fiddler crab.

The tree pipit is a small passerine bird which breeds across most of Europe and the Palearctic as far East as the East Siberian Mountains. It is a long-distance migrant moving in winter to Africa and southern Asia. The scientific name is from Latin: anthus is the name for a small bird of grasslands, and the specific trivialis means "common".

The forest wagtail is a medium-sized passerine bird in the wagtail family Motacillidae. It has a distinctive plumage that sets it apart from other wagtails and has the habit of wagging its tail sideways unlike the usual up and down movements of the other wagtail species. It is the only wagtail species that nests in trees. It is found mainly in forested habitats, breeding in the temperate parts of east Asia and wintering across tropical Asia from India to Indonesia.

Hemimacronyx is a proposed genus of birds in the pipit and wagtail family Motacillidae. It contains two species that are usually treated as belonging to two larger genera, Macronyx and Anthus. The plumage of the two species is more similar to that of the longclaws and the golden pipit, having brown barred backs and bright yellow breasts and throats. They are presumed to be closely related to these two groups, but the split has not been widely recognised. Both species are found in open areas of Africa. They are both threatened with extinction due to human activities, principally habitat loss.
