The yellow-billed babbler (Argya affinis) 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. [2] Its name is also confused with Turdoides leucocephala, which is also known as white-headed babbler.
The yellow-billed babbler was formerly placed in the genus Turdoides but following the publication of a comprehensive molecular phylogenetic study in 2018, it was moved to the resurrected genus Argya . [3] [4]
These birds have grey brown upperparts, a grey throat and breast with some mottling, and a pale buff belly. The head and nape are grey, and the eyes are bluish white. The nominate race, found in southern India, has a whitish crown and nape, with a darker mantle. The rump is pale and the tail has a broad dark tip. The Sri Lankan subspecies A. a. taprobanus is drab pale grey. Birds in the extreme south of India are very similar to the Sri Lankan subspecies with the colour of the crown and back being more grey than the nominate race. The Indian form is more heavily streaked on the throat and breast. [5] The Sri Lankan subspecies resembles the jungle babbler, Turdoides striatus, although that species does not occur on the island. [6]
Seven distinctive vocalisations have been noted in this species and this species has a higher pitched call than the jungle babbler. The jungle babbler has calls that have a harsher and nasal quality. [7]
The taxonomy of this species was confused in the past and confounded with the sympatric jungle babbler and the orange-billed babbler of Sri Lanka. [8] [9]
This species is patchily distributed in southern India and Sri Lanka. The nominate subspecies is found in Andhra Pradesh, south of the Godavari river and Karnataka south of Belgaum into Tamil Nadu. It prefers lower altitudes and drier habitats than the jungle babbler but sometimes is found alongside it. The Sri Lankan subspecies is found in the lowlands and hills up to about 1500m avoiding heavy forest. [6] It is a common garden bird and frequently visits urban and suburban areas.
The yellow-billed babbler lives in flocks of seven to ten or more. It is a very noisy bird, and the presence of a flock may generally be known at some distance by the continual chattering, squeaking and chirping produced by its members. Sometimes, all the members start chattering loud enough to irritate the human ear significantly. One member often perches high and acts as a sentinel while the remaining members of the flock forage on or close to the ground. They feed mainly on insects, but also eat fruit, nectar and human food scraps. [10] They have been known to take Calotes versicolor lizards and whip-scorpions. [6] They do not fly long distances; the maximum distance flown non-stop was about 180 m and prior to flying, they usually gain height by moving up a tree or tall shrub. Black drongos, rufous treepies and Indian palm squirrels are often seen foraging near these babblers. [11] [12]
The babblers wake before dawn around 6:00 AM and begin foraging. They are relatively inactive in the hot hours of the day from 1:30 PM to 4:30 PM. They assemble in groups around 7:00 PM and preen themselves before going to roost. Members of a group roost next to each other with some juveniles wedging themselves in the middle of the group. When foraging the sentinel bird calls with wing fluttering and hopping. Allopreening is a common activity, particularly in winter, [11] and members may beg for food from other members. [7] Yellow-billed babblers particularly like to bathe, and may visit birdbaths in their general territories, usually around late afternoon to evening. Sometimes these birds have been observed visiting bird baths at around 6:30 PM, after sunset.
A study in the Sivakasi plains noted that groups had a home range of 0.4 km2 and the population density was about 55 birds per km2. [11]
Nests of the species are seen throughout the year but the peak breeding season is prior to the onset of the Indian southwest monsoon. Nests are built in trees, concealed in dense masses of foliage. The majority of nests are built below a height of four metres from the ground. The nest is a small cup placed in a fork of a branch. The normal clutch is two to four turquoise blue eggs, although up to five may be laid by birds in the hills of Sri Lanka. The eggs hatch after 14 to 16 days. [2] The brooding parent bird often stands on the rim of the nest rather than sit on the chicks. Brood parasitism of the babblers' nests by the pied cuckoo (Clamator jacobinus) is known from both India and Sri Lanka. [13] [14] [15] The common hawk-cuckoo has also been noted as a brood parasite. [2] [16] In an exceptional case, jungle babblers have been seen feeding the chicks of the yellow-billed babbler. [17] Chicks are mainly fed insects and the occasional lizard. Like most perching birds, the parents take care of nest sanitation, removing the faecal sacs of the young, typically by swallowing them. [18] [19] Helpers have been seen to assist the parents in building the nest [2] as well as in feeding the chicks at the nest. [20]
Predators of the eggs include mongoose, crows and the greater coucal which may also prey on chicks. Rat snakes ( Ptyas mucosus ) may sometimes take chicks. [2]
In Sri Lanka, this bird is known as demalichcha in Sinhala language. [21] In Tamil Nadu, this bird is known as Thavittu-kuruvi, Pandri-kuruvi, Velaikkara-kuruvi, Kalani-kuruvi, Pooniyal kuruvi,Oor kuruvi in Tamil language. [22]
The yellow-wattled lapwing is a lapwing that is endemic to the Indian Subcontinent. It is found mainly on the dry plains of peninsular India and has a sharp call and is capable of fast flight. Although they do not migrate, they are known to make seasonal movements in response to rains. They are dull grey brown with a black cap, yellow legs and a triangular wattle at the base of the beak. Like other lapwings and plovers, they are ground birds and their nest is a mere collection of tiny pebbles within which their well camouflaged eggs are laid. The chicks are nidifugous, leaving the nest shortly after hatching and following their parents to forage for food.
The Indian white-eye, formerly the Oriental white-eye, is a small species of 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. Their name was recently changed due to previous members of Zosterops palpebrosus in Southeast Asia being renamed to a new species, making the Indian White-eye a more geographically accurate term for this species.
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.
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. Punjab tailor birds produce shiny red eggs, but became extinct around 1975 due to laying their eggs in fields used to grow fodder crops.
The Indian nightjar is a small nightjar which is a resident breeder in open lands across South Asia and Southeast Asia. Like most nightjars it is crepuscular and is best detected from its characteristic calls at dawn and dusk that have been likened to a stone skipping on a frozen lake - a series of clicks that become shorter and more rapid. They are sometimes spotted on roads when their eyes gleam red in the spotlight of a vehicle. There is considerable plumage variation across its range and can be hard to differentiate from other nightjars in the region especially in the field.
The Jacobin cuckoo, also pied cuckoo or pied crested cuckoo, is a member of the cuckoo order of birds that is found in Africa and Asia. It is partially migratory and in India, it has been considered a harbinger of the monsoon rains due to the timing of its arrival. It has been associated with a bird in Indian mythology and poetry, known as the chātaka represented as a bird with a beak on its head that waits for rains to quench its thirst.
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 lap nectar from flowers. They build a hanging pouch nest made up of cobwebs, lichens and plant material. Males are contrastingly 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 from males by their whitish throats.
The yellow-browed bulbul, 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.
The jungle babbler is a member of the family Leiothrichidae found in the Indian subcontinent. Jungle babblers are gregarious birds that forage in small groups of six to ten birds, a habit that has given them the popular name of "Seven Sisters" in urban Northern India, and in Bengali, with cognates in other regional languages which also mean "seven brothers".
The tawny-bellied babbler also known in older Indian works as the rufous-bellied babbler is a small babbler that forages in small groups in low scrub forests. Like other members of the large Old World babbler family they are passerine birds characterised by soft fluffy plumage. There are three subspecies within the Indian Subcontinent. The nominate hyperythra found in northern and eastern India is uniformly brown underneath while albogularis of the western Indian peninsula is white throated. The population in Sri Lanka, phillipsi, is also white throated but is paler underneath and has a larger bill.
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, curved yellow, scimitar-shaped bills give them their name. It has been treated in the past as a 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.
The dark-fronted babbler is an Old World babbler found in the Western Ghats of India and the forests of Sri Lanka. They are small chestnut brown birds with a dark black cap, a whitish underside and pale yellow iris. They forage in flocks in the undergrowth of forests constantly making calls and uttering alarm calls when disturbed.
The Indian robin is a species of passarine bird in the family Muscicapidae. It is widespread in the Indian subcontinent and ranges across Bangladesh, Bhutan, India, Nepal, Pakistan and Sri Lanka. The males of the northern subspecies have brown backs whose extent gradually reduces southwards, with the males of the southern subspecies having all-black backs. They are commonly found in open scrub areas and often seen running along the ground or perching on low thorny shrubs and rocks. The long tail is usually held up and the chestnut undertail coverts and dark body make them easily distinguishable from pied bushchats and Oriental magpie-robins.
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.
The common hawk-cuckoo, popularly known as the brainfever bird, is a medium-sized cuckoo resident in the Indian subcontinent. It bears a close resemblance to the Shikra, even in its style of flying and landing on a perch. The resemblance to hawks gives this group the generic name of hawk-cuckoo and like many other cuckoos these are brood parasites, laying their eggs in nests of babblers. During their breeding season in summer males produce loud, repetitive three note calls that are well-rendered as brain-fever, the second note being longer and higher pitched. These notes rise to a crescendo before ending abruptly and repeat after a few minutes; the calling may go on through the day, well after dusk and before dawn.
The baya weaver is a weaverbird found across the Indian Subcontinent and Southeast Asia. Flocks of these birds are found in grasslands, cultivated areas, scrub and secondary growth and they are best known for their hanging retort shaped nests woven from leaves. These nest colonies are usually found on thorny trees or palm fronds and the nests are often built near water or hanging over water where predators cannot reach easily. They are widespread and common within their range but are prone to local, seasonal movements mainly in response to rain and food availability.
The large gray babbler is a member of the family Leiothrichidae found across India and far western Nepal. They are locally common in the scrub, open forest and gardenland. They are usually seen in small groups and are easily distinguished from other babblers in the region by their nasal call and the whitish outer feathers to their long tail. It is one of the largest babblers in the region.
The common babbler is a member of the family of Leiothrichidae. They are found in dry open scrub country mainly in India. Two populations are recognized as subspecies and the populations to the west of the Indus river system are now usually treated as a separate species, the Afghan babbler. The species is distinctly long-tailed, slim with an overall brown or greyish colour, streaked on the upper plumage and having a distinctive whitish throat.
The Wayanad laughingthrush is a species of laughingthrush in the family Leiothrichidae. It is endemic to the Western Ghats south of Goa in India. These laughingthrushes move in groups in dense forests, producing loud calls but tend to be hard to spot in the undergrowth. They have brown upperparts, a white throat, a broad black mask through the eye and a heavy bill with pale yellow on the lower mandible. Despite the name, derived from the Wayanad region, this species has a wider range than the four other south Indian species of laughingthrush that are restricted to the higher elevation hills.
