Anthus nilghiriensis Sharpe, 1885 | |
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 .
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.

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]
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]
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]
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]
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.
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.
The water pipit is a small passerine bird which breeds in the mountains of Southern Europe and the Palearctic eastwards to China. It is a short-distance migrant; many birds move to lower altitudes or wet open lowlands in winter.
Richard's pipit is a medium-sized passerine bird which breeds in open grasslands in the East Palearctic. It is a long-distance migrant moving to open lowlands in the Indian subcontinent and Southeast Asia. It is a rare but regular vagrant to western Europe.
The meadow pipit is a small passerine bird, which breeds in much of the Palearctic, from southeastern Greenland and Iceland east to just east of the Ural Mountains in Russia, and south to central France and Romania; an isolated population also occurs in the Caucasus Mountains. It is migratory over most of its range, wintering in southern Europe, North Africa, and south-western Asia, but is resident year-round in western Europe, though even here many birds move to the coast or lowlands in winter.
The red-throated pipit is a small passerine bird, which breeds in the far north of Europe and the Palearctic, with a foothold in northern Alaska. It is a long-distance migrant, moving in winter to Africa, South and East Asia and the West Coast United States. It is a vagrant to Western Europe.
The Pechora pipit is a small passerine bird which breeds in the East Palearctic tundra and densely vegetated areas near river banks ranges from the Pechora River to the Chukchi Peninsula. It also breeds in Kamchatka and the Commander Islands. It is a long-distance migrant, moving in winter to Indonesia. Rarely in September and October, the Pechora pipit may be observed in western Europe. The species was first described by Robert Swinhoe in 1863.
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 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 American pipit, formerly known as the Buff-bellied pipit, is a small songbird native to North America. It was first described by Marmaduke Tunstall in his 1771 Ornithologia Britannica. It was formerly classified as a form of the water pipit. The former subspecies, Siberian pipit, is now considered a distinct species.
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.
The long-billed pipit or brown rock pipit is a passerine bird which has a wide distribution. A number of subspecies have been created for the populations in Africa, through the Arabian Peninsula and South Asia. The systematics of this complex is yet to be clarified. Most birds are residents or short distance migrants.
Sharpe's longclaw is a passerine bird in the longclaw family Motacillidae, which also includes the pipits and wagtails. It is endemic to Kenya.
The Australian pipit is a fairly small passerine bird of open country in Australia and New Guinea. It belongs to the pipit genus Anthus in the family Motacillidae.
The African pipit is a fairly small passerine bird belonging to the pipit genus Anthus in the family Motacillidae. It is also known as the grassveld pipit or grassland pipit. It was formerly lumped together with the Richard's, Australian, mountain and paddyfield pipits in a single species, Richard's pipit, but is now often treated as a species in its own right.
The New Zealand pipit is a fairly small passerine bird of open country in New Zealand and outlying islands. It belongs to the pipit genus Anthus in the family Motacillidae.
The alpine pipit is a species of bird in the family Motacillidae. It is found in New Guinea.
Hellmayr's pipit is a species of bird in the family Motacillidae. It is found in Argentina, Bolivia, Brazil, Chile, Paraguay, Peru, and Uruguay. Its natural habitats are temperate grassland, subtropical or tropical high-altitude grassland, and pastureland.
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.
Jackson's pipit is a rare and little-known African bird of the pipit and wagtail family.
