The yellow-eyed babbler (Chrysomma sinense) 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. [1]
Its common name refers to the traditional placement in the Old World babbler family Timaliidae although the genus Chrysomma forms a clade along with the parrotbills within the family Paradoxornithidae. [2]
The yellow-eyed babbler was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae . He placed it with the tits and manakins in the genus Parus and coined the binomial name Parus sinensis. [3] Gmelin based his account on the "Chinese titmouse" that had been described in 1783 by the English ornithologist John Latham in his book A General Synopsis of Birds. [4] Gmelin gave the type locality as China but it is now restricted to the province of Guangdong. [5] The yellow-eyed babbler is now placed together with Jerdon's babbler in the genus Chrysomma that was introduced in 1843 by the English zoologist Edward Blyth. [6]
Three subspecies are recognised: [6]
The yellow-eyed babbler is about 18 centimetres (7.1 in) long with a short bill and a long graduated tail. The body above is brown and the wings are cinnamon coloured. The lores and supercilium are white and the rim of the eye is orange-yellow in adult birds. The beak is black. The underside is whitish buff. The central tail feathers are about twice as long as the outermost. The sexes are indistinguishable in the field. [7] [8]
Within its wide distribution range there are some differences in plumage between populations that have been considered as subspecies. The nominate subspecies is found in Burma, Laos and Thailand. The population in Sri Lanka, nasale, has black nostrils and a stouter bill. [9] The population across much of India, hypoleucum, has yellow nostrils (as with the nominate subspecies) and is paler in plumage. The population in the northeast Duars of India has an almost slaty crown and darker wings and has been called as saturatius or saturatior but this is considered as clinal variation and included in the nominate population. [10] [11]
The range of the yellow-eyed babbler extends from Pakistan through India, Nepal, Sri Lanka to Bangladesh, Myanmar, Thailand, Laos, Viet Nam and China. [1]
The usual habitat is grassy or thorny scrub both in dry and wet regions as well as farmland. It occurs mainly on the plains but also in the lower hills up to 1200 m. [7] It is absent in the dense forest region of the Western Ghats and occurs only on the eastern edges or in gaps such as at Palghat. [12]

Like babblers, these birds are usually seen in small groups of five to fifteen, especially in the non-breeding season. They are usually found inside bushes, emerging up to the top of a stem and then diving back into cover to forage. They feed mainly on insects but take berries ( Lantana and Salvadora ) as well as nectar. When capturing insects, they may hold them down with their feet. [13] The group constantly produces a series of cheeping or churring calls. During the breeding season, mainly the southwest monsoon (June to August) but sometimes during the receding monsoon, [14] [15] [16] the song is a strong whistling twee-twee-ta-whit-chu, often delivered from a prominent perch. The colour of the inside of the mouth is said to turn from orange-brown to black during the breeding season. They appear to nest cooperatively, the nest being a deep cone made with grass and lined with fine fibre. The nest is wedged between upright stems, the vertical stems being incorporated into the wall of the nest. The outside of the nest is well covered in cobwebs. The usual clutch is four but varies from three to five. The eggs are pinkish white with chestnut-red patches. Both parents take part in incubation and feeding the young. The eggs hatch after about 15–16 days and the young birds fledge after about 13 days. Adult birds have been seen feigning injury presumably to detract predators. [7] Birds roost communally in the centre of a bush, all facing in the same direction and sitting side by side. Members of a group will preen each other. In an apparent territorial display, a pair of birds were found to sing while facing another singing pair and they all simultaneously bobbed their heads while perching on legs held straight to appear tall. [17] [18]
Shikras have been observed attempting to prey on these birds. [19]
Known in parts of northern India as gulab chashm meaning "yellow spectacles", they were sometimes kept as cagebirds. [20] [21]
The puff-throated babbler or spotted babbler is a species of passerine bird found in Asia. They are found in scrub and moist forest mainly in hilly regions. They forage in small groups on the forest floor, turning around leaf litter to find their prey and usually staying low in the undergrowth where they can be hard to spot. However, they have loud and distinct calls, including a morning song, contact and alarm calls. It is the type species of the genus Pellorneum which may, however, currently include multiple lineages.
The shikra is a small bird of prey in the family Accipitridae found widely distributed in Asia and Africa where it is also called the little banded goshawk. The African forms may represent a separate species but have usually been considered as subspecies of the shikra. The shikra is very similar in appearance to other sparrowhawk species including the Chinese goshawk and Eurasian sparrowhawk. They have a sharp two note call and have the typical flap and glide flight. Their calls are imitated by drongos and the common hawk-cuckoo resembles it in plumage.
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. 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 white-browed wagtail or large pied wagtail is a medium-sized bird and is the largest member of the wagtail family. They are conspicuously patterned with black above and white below, a prominent white brow, shoulder stripe and outer tail feathers. White-browed wagtails are native to South Asia, common near small water bodies and have adapted to urban environments where they often nest on roof tops. The specific name is derived from the Indian city of Madras.
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.
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 red-vented bulbul is a member of the bulbul family of passerines. It is a resident breeder across the Indian subcontinent, including Sri Lanka extending east to Burma and parts of Bhutan and Nepal. It has been introduced in many other parts of the world and has established itself in New Zealand, Argentina, Tonga and Fiji, as well as parts of Samoa, Australia, USA and Cook Islands. It is included in the list of the world's 100 worst invasive alien species.
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 Turdoides leucocephala, which is also known as white-headed 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 curved 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.
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 brahminy starling or brahminy myna is a member of the starling family of birds. It is usually seen in pairs or small flocks in open habitats on the plains of the Indian subcontinent.
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 grey-headed canary-flycatcher, sometimes known as the grey-headed flycatcher, is a species of small flycatcher-like bird found in tropical Asia. It has a square crest, a grey hood and yellow underparts. They are found mainly in forested habitats where they often join other birds in mixed-species foraging flocks. Pairs are often seen as they forage for insects by making flycatcher-like sallies and calling aloud. Several subspecies are recognized within their wide distribution range. In the past the genus Culicicapa was considered to be an Old World flycatcher but studies have found them to belong to a new family designated as the Stenostiridae or fairy flycatchers that include the African genera Stenostira and Elminia.
The ashy drongo is a species of bird in the drongo family Dicruridae. It is found widely distributed across eastern and Southeast Asia, with several populations that vary in the shade of grey, migration patterns and in the size or presence of white patches around the eye.
The common iora is a small passerine bird found across the tropical Indian subcontinent and Southeast Asia, with populations showing plumage variations, some of which are designated as subspecies. A species found in scrub and forest, it is easily detected from its loud whistles and the bright colours. During the breeding season, males display by fluffing up their feathers and spiral in the air appearing like a green, black, yellow, and white ball.
The greater hoopoe-lark is a passerine bird which is a breeding resident of arid, desert and semi-desert regions from the Cape Verde Islands across much of northern Africa, through the Arabian peninsula, Syria, Afghanistan, Pakistan and India. It was formerly known as the bifasciated lark and sometimes as the large desert lark.
The grey francolin is a species of francolin found in the plains and drier parts of the Indian subcontinent and Iran. This species was formerly also called the grey partridge, not to be confused with the European grey partridge. They are mainly ground-living birds and are found in open cultivated lands as well as scrub forest and their local name of teetar is based on their calls, a loud and repeated Ka-tee-tar...tee-tar which is produced by one or more birds. The term teetar can also refer to other partridges and quails. During the breeding season calling males attract challengers, and decoys were used to trap these birds especially for fighting.
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 common woodshrike is a species of bird found in Asia. It is now usually considered a member of the family Vangidae. It is small and ashy brown with a dark cheek patch and a broad white brow. It is found across Asia mainly in thin forest and scrub habitats where they hunt insects, often joining other insectivorous birds. The form found in Sri Lanka which was treated as a subspecies is now usually considered a separate species, the Sri Lanka woodshrike.
Jerdon's babbler is a passerine bird native to wetlands and grasslands of the Indian sub-continent. It is listed as Vulnerable on the IUCN Red List since 1994. It is a member of the genus Chrysomma of the family Paradoxornithidae.
