Distribution of members in the species complex

The Nilgiri flowerpecker (Dicaeum concolor) is a tiny bird in the flowerpecker family. Formerly a subspecies of what used to be termed as the plain flowerpecker although that name is now reserved for Dicaeum minullum. Like others of the group, it feeds predominantly on nectar and fruits. They forage within the canopy of forests and are found in India. They are non-migratory and the widespread distribution range includes several populations that are non-overlapping and morphologically distinct, some of which are recognized as full species. They are important pollinators and dispersers of mistletoes in forests.

Description

These birds are tiny (9 cm long) and there is no marked difference between the males and females. It is found in hill forests of the Western Ghats and Nilgiri hills of southern India. It is pale brown on the upperside and the underside is whitish. The whitish brow in front of the eye is wider than in Dicaeum erythrorhynchos . This subspecies has been raised to full species by Pamela Rasmussen. The subspecies found in northeastern India, extending into Myanmar, Laos and southern China is called olivaceum by earlier authors but is treated by Rasmussen and other taxonomists now as a separate species Dicaeum minullum (which includes the population minullum from Hainan Island and is now termed as the plain flowerpecker in the more restricted sense). This is very olive above and the black bill is finer and slightly curved. The population found in the Andaman Islands virescens is also considered a separate species Dicaeum virescens (the Andaman flowerpecker) in the newer treatment. This is bright olive-green on the upperside with dark speckling on the crown. The centre of the belly has a bright patch of pale yellow. [2]

Behaviour and ecology

The Nilgiri flowerpecker is a common resident breeding bird of woodland edges, cultivation and isolated stands of trees, often in hilly country. The call of the Nilgiri flowerpecker is a sharp check or a rapid series of ticks, while the song is a high-pitched trill. The breeding season of concolor in the Nilgiris is January to April possibly with a second brood in May and June. [3] Two or three eggs are laid in a purse-like nest suspended from a tree or bush. [4] Like other flowerpeckers they have a feathery tongue that allows them to sip nectar, but they feed on soft berries as well as small insects.

They are important pollinators and dispersers of mistletoes in tropical forests. [5]

Flowerpecker Family of birds

The flowerpeckers are a family, Dicaeidae, of passerine birds. The family comprises two genera, Prionochilus and Dicaeum, with 48 species in total. The family has sometimes been included in an enlarged sunbird family Nectariniidae. The berrypeckers of the family Melanocharitidae and the painted berrypeckers, Paramythiidae, were once lumped into this family as well. The family is distributed through tropical southern Asia and Australasia from India east to the Philippines and south to Australia. The family has a wide range occupying a wide range of environments from sea level to montane habitats. Some species, such as the mistletoebird of Australia, are recorded as being highly nomadic over parts of their range.

Indian white-eye Species of bird

The Indian white-eye, formerly the Oriental white-eye, is a small passerine bird in the white-eye family. It is a resident breeder in open woodland on the Indian subcontinent. They forage in small groups, feeding on nectar and small insects. They are easily identified by the distinctive white eye-ring and overall yellowish upperparts. The range previously extended eastwards to Southeast Asia, Indonesia and Malaysia but when the taxa in these regions were assigned to other species, the English name was changed.

Pompadour green pigeon Species of bird

The pompadour green pigeon is a pigeon species complex. It is widespread in forests of southern and southeast Asia. Many authorities have split the pompadour green pigeon into multiple species, which are listed below:

Purple-rumped sunbird Species of bird

The purple-rumped sunbird is a sunbird endemic to the Indian Subcontinent. Like other sunbirds, they are small in size, feeding mainly on nectar but sometimes take insects, particularly when feeding young. They can hover for short durations but usually perch to suck nectar from flowers. They build a hanging pouch nest made up of cobwebs, lichens and plant material. Males are brightly coloured but females are olive above and yellow to buff below. Males are easily distinguished from the purple sunbird by the light coloured underside while females can be told apart by their whitish throats.

Crimson-backed sunbird Species of bird

The crimson-backed sunbird or small sunbird is a sunbird endemic to the Western Ghats of India. Like other sunbirds, they feed mainly on nectar although they take insects, especially to feed their young. They are tiny birds that are resident and are found in forests but are particularly attracted to gardens at the edge of the forest where people grow suitable flower-bearing plants. They usually perch while taking nectar.

White-bellied blue flycatcher Species of bird

The white-bellied blue flycatcher is a small passerine bird in the flycatcher family Muscicapidae. It is endemic to the Western Ghats of southwest India. Males are dark blue with a lighter shade of blue on the brow and have a greyish white belly. Females have a rufous breast, a white face and olive grey above.

<i>Dicaeum</i> Genus of birds

Dicaeum is a genus of birds in the flowerpecker family Dicaeidae, a group of passerines tropical southern Asia and Australasia from India east to the Philippines and south to Australia. The genus is closely related to the genus Prionochilus and forms a monophyletic group.

Thick-billed flowerpecker Species of bird

The thick-billed flowerpecker is a tiny bird in the flowerpecker group. They feed predominantly on fruits and are active birds that are mainly seen in the tops of trees in forests. It is a resident bird with a wide distribution across tropical southern Asia from India east to Indonesia and Timor with several populations recognized as subspecies some of which are sometimes treated as full species.

White-bellied woodpecker Species of bird

The white-bellied woodpecker or great black woodpecker is found in evergreen forests of tropical Asia, including the Indian subcontinent and Southeast Asia. It has 14 subspecies, part of a complex including the Andaman woodpecker. Many of its island forms are endangered, and some are extinct. Populations differ in the distribution and extent of white. They are among the largest of the Asiatic woodpeckers and nest in large dead trees, often beside rivers. Their drums and calls are louder than those of the smaller woodpeckers.

Pale-billed flowerpecker Species of bird

The pale-billed flowerpecker or Tickell's flowerpecker is a tiny bird that feeds on nectar and berries, found in India, Sri Lanka, Bangladesh and western Myanmar. The bird is common especially in urban gardens with berry bearing trees. They have a rapid chipping call and the pinkish curved beak separates it from other species in the region.

Jungle owlet Species of owl

The jungle owlet, or barred jungle owlet, is found in the Indian Subcontinent. The species is often found singly, in pairs or small groups and are usually detected by their calls at dawn and dusk. There are two subspecies with the form found in the Western Ghats sometimes considered a full species.

Mistletoebird Species of bird

The mistletoebird, also known as the mistletoe flowerpecker, is a species of flowerpecker native to most of Australia and also to the eastern Maluku Islands of Indonesia in the Arafura Sea between Australia and New Guinea. The mistletoebird eats mainly the berries of the parasitic mistletoe and is a vector for the spread of the mistletoe's seeds through its digestive system.

Nilgiri laughingthrush Species of bird

The Nilgiri laughingthrush is a species of laughingthrush endemic to the high elevation areas of the Nilgiris and adjoining hill ranges in Peninsular India. The mostly rufous underparts, olive brown upperparts, a prominent white eyebrow and a black throat make it unmistakable. It is easily detected by its loud series of nasal call notes and can be hard to spot when it is hidden away inside a patch of dense vegetation. The species has a confusing taxonomic history, leading to a range of names. In the past the species was considered to have two subspecies, the nominate form in the Nilgiris and jerdoni with a grey upper breast and found in the Brahmagiris of Coorg and Banasura range of Wayanad. They are omnivorous, feeding on a range of insects, berries and nectar.

Nilgiri blue robin Species of bird

The Nilgiri blue robin, also known as Nilgiri shortwing, white-bellied shortwing, Nilgiri sholakili or rufous-bellied shortwing is a species of passerine bird in the family Muscicapidae endemic to the Shola forests of the higher hills of southern India, mainly north of the Palghat Gap. This small bird is found on the forest floor and undergrowth of dense forest patches sheltered in the valleys of montane grassland, a restricted and threatened habitat.

Fire-breasted flowerpecker Species of bird

The fire-breasted flowerpecker is a species of bird in the family Dicaeidae found in the Indian Subcontinent and Southeast Asia. Like other flowerpeckers, this tiny bird feeds on fruits and plays an important role in the dispersal of fruiting plants. Unlike many other species in the genus, this species has marked sexual dimorphism with the male having contrasting upper and lower parts with a distinctive bright orange breast patch. The female is dull coloured.

Black-sided flowerpecker Species of bird

The black-sided flowerpecker, also known as the Bornean flowerpecker, is a species of bird in the family Dicaeidae. It is endemic to the island of Borneo, where it is found in the mountains, primarily above 1,000 m (3,300 ft) in elevation. The species is sexually dimorphic. The male has glossy blue-black upperparts, with a scarlet throat and breast, a dark grey upper belly, olive flanks, a white lower belly, and a buffy vent and undertail coverts. The female is olive-green above and greyish below, with buffy flanks and a whitish throat. It inhabits a range of forest habitats, including primary and secondary montane forest, kerangas forest, and scrub, and is also occasionally found in gardens. It feeds primarily on small fruits—particularly mistletoe berries—as well as seeds, nectar, and various invertebrates. It builds a nest of moss, camouflaged on the outside with lichens and lined with the pith of tree ferns. The International Union for Conservation of Nature rates it as a species of least concern. Though its numbers have not been quantified, the black-sided flowerpecker is said to be common throughout much of its range, and any declines are not thought to be precipitous. However, destruction of forest for palm plantations may impact it.
