The yellow-browed bulbul (Acritillas indica), or golden-browed bulbul, is a species of songbird in the bulbul family, Pycnonotidae. It is found in the forests of southern India and Sri Lanka. The yellow-browed bulbul is mainly yellow on the underside and olive above with a distinct yellow brow. They are easily located by their loud calls but tend to skulk within foliage below the forest canopy. While its taxonomic classification has changed over time, it is currently the sole species within the monotypic genus Acritillas which is closely related to Hemixos .

Taxonomy and systematics

A. i. icterica at Dandeli, India

The yellow browed bulbul was originally described in the genus Trichophorus (a synonym for Criniger) in 1839 by T. C. Jerdon on the basis of specimens from the Wynaad region and given the original binomial (or protonym) of Trichophorus indicus. Formerly, the yellow-browed bulbul was classified in the genus Iole as two separate species but a study [2] determined that this species is exceptional and it is now placed in the monotypic genus Acritillas. [3] [4] [5] Some authorities have included the yellow-browed bulbul in the genus Hypsipetes but a 2018 molecular phylogenetic study indicated the nearest living relative as Hemixos flavala . [6]

Subspecies

Three subspecies are currently recognized: [7] [3]

Description

This bulbul is about 20 cm (7.9 in) long, lacks a crest and has the upperparts olive green with a prominent yellow brow and goggle with the underparts being all yellow. The sexes do not differ in plumage. The bill is black and the iris is reddish brown. The population in the northern Western Ghats (ssp. icterica) is paler yellow than the populations further south (ssp. indica). A somewhat disjunct population is found in the Eastern Ghats. Southwestern Sri Lankan populations (ssp. gugliemi) are greener while the northern populations are included in the nominate subspecies. [3] [8]

The calls include a whistle like call and sharp pick-wick notes.

Distribution and habitat

The yellow-browed bulbul has been considered as the wet-zone counterpart of the dry-zone white-browed bulbul. [4] It is found mainly below the forest canopy of the hill forests and plantations in the Western Ghats and Sri Lanka. They also occur in parts of the Eastern Ghats including the Kolli hills, [9] Nallamalas and parts of Tirupathi and Mamandur regions in Andhra Pradesh. [10] [11]

Behaviour and ecology

Yellow-browed bulbuls are found in pairs or small groups and call loudly. They feed mainly on berries and insects. The breeding season is during the dry spell before the monsoons, mainly January to May. The nest is a cup built in a low fork covered with moss and cobwebs on the outside, giving the appearance of a large white-eye nest, [4] and lined with fine root fibres. [8] The typical clutch size in India is three eggs and in Sri Lanka is two. A study of 153 nests in Silent Valley National Park of India found 92% of nests had two eggs. [12] Peak breeding in the Silent Valley National Park of Kerala was found in January and February. [12] About a week is taken for building the nest and the eggs are incubated for about 13 days. The eggs are pale pink or white with reddish brown speckling. [13] The eggs hatch synchronously and the nestlings fledge after about 13 days. [12] Nestlings are fed with caterpillars, soft insects and berries. [4]

Sri Lanka frogmouth Species of bird

The Sri Lanka frogmouth, Sri Lankan frogmouth or Ceylon frogmouth is a small frogmouth found in the Western Ghats of south India and Sri Lanka. Related to the nightjars, it is nocturnal and is found in forest habitats. The plumage coloration resembles that of dried leaves and the bird roosts quietly on branches, making it difficult to see. Each has a favourite roost that it uses regularly unless disturbed. It has a distinctive call that is usually heard at dawn and dusk. The sexes differ slightly in plumage.

Blue-faced malkoha Species of bird

The blue-faced malkoha or small green-billed malkoha, is a non-parasitic cuckoo found in the scrub and deciduous forests of peninsular India and Sri Lanka. It has a waxy, dark, blue-grey plumage on its upperparts and has a long tail with graduated white-tipped feathers. The throat and chin are dark with spiny pale feathers that are branched. The lower belly is a dull creamy to rufous colour. The bill is apple green, and a naked patch of blue skin surrounds the eye. The sexes are alike. The blue-faced malkoha is a bird of open forests and scrub jungle.

Common tailorbird

The common tailorbird is a songbird found across tropical Asia. Popular for its nest made of leaves "sewn" together and immortalized by Rudyard Kipling as Darzee in his Jungle Book, it is a common resident in urban gardens. Although shy birds that are usually hidden within vegetation, their loud calls are familiar and give away their presence. They are distinctive in having a long upright tail, greenish upper body plumage and rust coloured forehead and crown. This passerine bird is typically found in open farmland, scrub, forest edges and gardens. Tailorbirds get their name from the way their nest is constructed. The edges of a large leaf are pierced and sewn together with plant fibre or spider silk to make a cradle in which the actual nest is built.

Spot-billed pelican

The spot-billed pelican or grey pelican, is a member of the pelican family. It breeds in southern Asia from southern Pakistan across India east to Indonesia. It is a bird of large inland and coastal waters, especially large lakes. At a distance they are difficult to differentiate from other pelicans in the region although it is smaller but at close range the spots on the upper mandible, the lack of bright colours and the greyer plumage are distinctive. In some areas these birds nest in large colonies close to human habitations.

Black eagle

The black eagle. Like all eagles, it is in the family Accipitridae, and is the only member of the genus Ictinaetus. They soar over forests in the hilly regions of tropical and subtropical South and Southeast Asia, as well as southeastern China. They hunt mammals and birds, particularly at their nests. They are easily identified by their widely splayed and long primary "fingers", the characteristic silhouette, slow flight and yellow ceres and legs that contrast with their dark feathers.

Black-rumped flameback

The black-rumped flameback, also known as the lesser golden-backed woodpecker or lesser goldenback, is a woodpecker found widely distributed in the Indian subcontinent. It is one of the few woodpeckers that are seen in urban areas. It has a characteristic rattling-whinnying call and an undulating flight. It is the only golden-backed woodpecker with a black throat and a black rump.

Orange-breasted green pigeon Species of bird

The orange-breasted green pigeon is a pigeon found across tropical Asia south of the Himalaya across parts of the Indian Subcontinent and Southeast Asia. Like other green pigeons, it feeds mainly on small fruit. They may be found in pairs or in small flocks, foraging quietly and moving slowly on trees. The nape is blue-grey and the crown is yellowish green. The uppertail coverts are bronzed and the undertail coverts are unmarked rufous. The male has a pinkish band on the upper breast with a broader orange one below while the female has a bright yellow breast.

Purple sunbird

The purple sunbird is a small bird in the sunbird family found mainly in South and Southeast Asia but extending west into parts of the Arabian peninsula. Like other sunbirds they feed mainly on nectar, although they will also take insects, especially when feeding young. They have a fast and direct flight and can take nectar by hovering like a hummingbird but often perch at the base of flowers. The males can appear all black in harsh sunlight but the purple iridescence is visible on closer observation or under good light conditions. Females are olive above and yellowish below.

Crimson-backed sunbird

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-browed bulbul

The white-browed bulbul is a member of the bulbul family of passerine birds. It is a resident breeder in Sri Lanka and peninsular India. Largely olive coloured above with whitish underparts, it has a pale supercilium and a yellow vent. They are found in dense scrub habitats, where they skulk within vegetation and can be difficult to see although their loud and distinct burst of calls is distinctive.

Yellow-billed babbler

The yellow-billed babbler is a member of the family Leiothrichidae endemic to southern India and Sri Lanka. The yellow-billed babbler is a common resident breeding bird in Sri Lanka and southern India. Its habitat is scrub, cultivation and garden land. This species, like most babblers, is not migratory, and has short rounded wings and a weak flight and is usually seen calling and foraging in groups. It is often mistaken for the jungle babbler, whose range overlaps in parts of southern India, although it has a distinctive call and tends to be found in more vegetated habitats. Its name is also confused with T. leucocephala, which is also known as white-headed babbler.

Indian scimitar babbler

The Indian scimitar babbler is an Old World babbler. It is found in peninsular India in a range of forest habitats. They are most often detected by their distinctive calls which include an antiphonal duet by a pair of birds. They are often hard to see as they forage through dense vegetation. The long curve yellow, scimitar-shaped bills give them their name. It has been treated in the past as subspecies of the white-browed scimitar babbler which is found along the Himalayas but now separated into two species, the peninsular Indian species and the Sri Lanka scimitar babbler.

Yellow-eyed babbler

The yellow-eyed babbler is a passerine bird native to South and Southeast Asia. It inhabits shrubland, grassland and wetland habitats. On the IUCN Red List, it is listed as Least Concern because of its wide distribution and stable population.

Pale-billed flowerpecker

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.

Yellow-throated bulbul

The yellow-throated bulbul is a species of songbird in the bulbul family of passerine birds. It is endemic to southern peninsular India. They are found on scrub habitats on steep, rocky hills many of which are threatened by granite quarrying. It is confusable only with the white-browed bulbul with which its range overlaps but is distinctively yellow on the head and throat apart from the yellow vent. The calls of this species are very similar to that of the white-browed bulbul.

Jungle nightjar Species of bird

The jungle nightjar is a species of nightjar found in Bangladesh, India, and Sri Lanka. It is found mainly on the edge of forests where it is seen or heard at dusk. The taxonomy of this and related nightjars is complex and a range of treatments have been followed that cover this and several other nightjars in the Asian region. It was formerly called the grey nightjar or Indian jungle nightjar and sometimes included the East Asian grey nightjar as a subspecies.

Painted francolin Species of bird

The painted francolin or painted partridge is a species of francolin found in grassy areas in central and southern India and in the lowlands of southeastern Sri Lanka. They are easily detected by their loud calls especially during the breeding season. Thomas C. Jerdon noted that the species was found mainly in Central India south of the Narmada and to the east of the Western Ghats as well as the Chota Nagpur and Northern Circars. It can be confused only with the black francolin with which it partly overlaps and is said to sometimes hybridize. This species can be told apart from the female of a black francolin by the lack of a rufous hind collar and the white spots on the underside. The face is rufous and there is no dark stripe running behind the eye.

<i>Criniger</i>

Criniger is a genus of songbirds in the bulbul family, Pycnonotidae. The species of Criniger are found in western and central Africa.

<i>Hypsipetes</i>

Hypsipetes is a genus of bulbuls, songbirds in the family Pycnonotidae. Most of its species occur in tropical forests around the Indian Ocean. But while the genus is quite diverse in the Madagascar region at the western end of its range it does not reach the African mainland.

<i>Iole</i> (genus)

Iole is a genus of songbirds in the bulbul family, Pycnonotidae. They are native to tropical eastern Asia, from India to China and south through Southeast Asia to northern Indonesia.
