The Nilgiri pipit (Anthus nilghiriensis) is a distinctive species of pipit that is endemic to the high altitude hills of southern India. Richer brown in colour than other pipits in the region, it is distinctive in having the streaking on the breast continuing along the flanks. It is non-migratory and has a tendency to fly into low trees when disturbed and is closely related to the tree pipits Anthus hodgsoni and Anthus trivialis .

Description

The Nilgiri pipit is about 12.6–14 centimetres (5.0–5.5 in) long and is richly coloured, has dark lores, a buff supercilium and throat. It lacks any malar stripes. The flanks, breast and sides of neck are brighter buff and that bill is completely dark. The crown is heavily streaked in black as are the upperparts. The outer tail feathers are also buff coloured and there is no white in the plumage. The streaking on the breast is fine and it extends along the flanks. [2] [3] [4]

The first four primaries of the wing are almost equal and the fifth is about 1–2 mm shorter. The primaries from the second to the fifth are emarginate. The tail feathers are pointed and the second outer feather has a tapering triangle along the shaft and the third with a small triangle at the tip. [5] Abnormal albino individuals have been reported. [6]

Phylogeny of living relatives [7]

The species was first described by Jerdon in 1840 under the name of Anthus rufescens, a name already used by Temminck for a different species. Blyth referred to it under the name of Anthus montanus. These are however invalid names and it was redescribed under replacement name of A. nilghiriensis by Richard Bowdler Sharpe in 1885. [8]

The Nilgiri pipit is closely related to the tree pipits and is a sister to the clade containing Anthus trivialis and Anthus hodgsoni from which it diverged in the Pliocene. [7]

Distribution and habitat

The Nilgiri pipit is closely associated with short montane grasslands interspersed with marshy grounds and small streams mostly in hill slopes above 1,000 metres (3,300 ft) in the Ponmudi hills and above 1,500 metres (4,900 ft) in the Nilgiris, Palani and High Ranges. [5] They have also been claimed to occur in the Kalakkad Mundanthurai Tiger Reserve [9] but a 2014 study suggests that the species is restricted to the high altitude grassy peaks of the Nilgiris and the Anamalais. Museum specimens exist from the Palani ranges but habitat changes may have led to its reduction or extirpation as the species was not found in surveys in the 21st century. [10]

Behaviour

Nilgiri pipits are found singly or in pairs. When disturbed they usually fly into a low bush or tree. [2] They breed in summer from April to July. The nest is a cup of grass in short grass. The clutch consists of two to three grey brown speckled eggs. [5] They feed on grass seeds and insects with invertebrates becoming more important during the breeding season. [1]

Status

The world population is estimated to be about 4000 birds based on a density estimate of about 0.1 birds per hectare in suitable habitat. The grassland habitat is threatened by wattle plantations and the colonization of grasslands by species such as broom ( Cytisus scoparius ) in the Nilgiris and by fire. [1] [11] [12]

<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 just 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 olive-backed pipit is a small passerine bird of the pipit (Anthus) genus, which breeds across southern, north central and eastern Asia, as well as in the north-eastern European Russia. It is a long-distance migrant moving in winter to southern Asia and Indonesia. Sometimes it is also called Indian pipit or Hodgson's pipit, as well as tree pipit owing to its resemblance with the tree pipit. However, its back is more olive-toned and less streaked than that species, and its head pattern is different with a better-marked supercilium.

The buff-bellied pipit or American pipit is a small songbird found on both sides of the northern Pacific. It was first described by Marmaduke Tunstall in his 1771 Ornithologia Britannica.

<span class="mw-page-title-main">Paddyfield pipit</span> Species of bird

The paddyfield pipit or Oriental pipit is a small passerine bird in the pipit and wagtail family. It is a resident (non-migratory) breeder in open scrub, grassland and cultivation in southern Asia east to the Philippines. Although among the few breeding pipits in the Asian region, identification becomes difficult in winter when several other species migrate into the region. The taxonomy of the species is complex and has undergone considerable changes.

<span class="mw-page-title-main">Madanga</span> Species of bird

The madanga or rufous-throated white-eye is a species of bird that was formerly included in the family Zosteropidae but is now thought to be an atypical member of the family Motacillidae, consisting of the pipits and wagtails. Its close relatives are tree pipits of the genus Anthus, and is endemic to the moist, mountainous, subtropical and tropical forest of the Indonesian island Buru. The bird was initially described from four specimens collected in April 1922 from one area in the western part of the island, near the settlement Wa Fehat, at elevations between 820 m (2,690 ft) and 1,500 m (4,900 ft). These observations were reproduced on two birds in December 1995 at Wakeika, at an elevation of 1,460 m (4,790 ft); changes in the bird's habitat at Wa Fehat were also noted in 1995. The bird was observed only in a few localities and neither its habitat area nor population is reliably known. The population is estimated at more than several hundred individuals, and the habitat at several hundred km2 from the available area above 1,200 m (872 km²) and above 1,500 m (382 km²); the birds are believed to disperse over their habitat rather than form groups. Because the species is restricted to a single island and its habitat is threatened by logging and other human activities, it is listed as endangered by the IUCN since 1996.

<span class="mw-page-title-main">Wood pipit</span> Species of bird

The wood pipit or woodland pipit is a small passerine bird belonging to the pipit genus Anthus in the family Motacillidae. It was formerly included in the long-billed pipit but is now frequently treated as a separate species. It is a bird of miombo woodland in south-central Africa, unlike the long-billed pipit which inhabits open grassland. It perches in trees when flushed but forages on the ground for invertebrates.
