The Indian white-eye (Zosterops palpebrosus), 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 Indian white-eye was described by the Dutch zoologist Coenraad Jacob Temminck in 1824 from a specimen collected in Bengal. He coined the binomial name Sylvia palpebrosa. [2] The English and scientific names refer to the conspicuous ring of white feathers round the eyes, palpebrosus being Neo-Latin for "having prominent eyelids", from the Latin palpebrae "eyelids". [3]
The English name of this species was changed from "Oriental white-eye" to "Indian white-eye" to more accurately reflect the geographic range following the reorganisation of the taxa with the introduction of Hume's white-eye (Zosterops auriventer), the warbling white-eye (Zosterops japonicus) and Swinhoe's white-eye (Zosterops simplex). [4]
This bird is small (about 8–9 cm long) with yellowish olive upper parts, a white eye ring, yellow throat and, a vent. The belly is whitish grey but may have yellow in some subspecies. The sexes look similar. The species is widespread and is part of a superspecies complex that includes Zosterops japonicus , Zosterops meyeni and possibly others. The taxonomy of the group is still unclear with some island populations being distinctive while some subspecies are not well supported. The population from Flores, Indonesia for instance is found closer to the pale white-eye. The family itself is now questioned since they are nested along with the Stachyris babblers. [5]
About eleven subspecies are well recognised, these include the nominate form (type locality Bengal, India) which is found from Oman and Arabia, Afghanistan, northern India and extends into China and northern Myanmar. The population in the Western Ghats and hills of southern India is placed in nilgiriensis while salimalii of the Eastern Ghats hills (Shevaroy, Chitteri, Seshachalam, Nallamalai) is sometimes subsumed into the nominate race. The population of the plains of India, Laccadives and Sri Lanka are sometimes placed in egregius (= egregia) but is restricted by other works to the population in Sri Lanka. [6] [7] The populations in southern Myanmar, Thailand and Laos are placed in siamensis. The Nicobar Islands form is nicobaricus and is sometimes also used for the population on the Andaman Islands which are, however, a distinctive and unnamed population. [6] The populations from southern Thailand to western Cambodia are placed in williamsoni. [8] Other Southeast Asian island forms include auriventer (=aureiventer), buxtoni, melanurus and unicus.
Race occidentis (now often subsumed into the nominate race) of the Western Himalayas has the upper side dark green and the flanks are tinged in brown. The form salimalii has a shorter bill and is brighter yellow-green above. [6] [9] Some authors consider the nominate race to be restricted to Sikkim, Bhutan, Assam and Yunnan and consider the peninsular race as occidentis [10] (or amabilis if the form from Kathiawar described by Koelz is considered valid). [6] [11]
In Sri Lanka, race egregia is smaller and has a brighter back and throat than the endemic Sri Lanka white-eye, Zosterops ceylonensis found in the central hills.
The species is found in a wide range of habitats from scrub to moist forest. They sometimes occur in mangrove areas, such as in the Karachi region, Pakistan, [12] and on islands they may lead a more insectivorous life. [13] They are somewhat rare only in the drier desert regions of western India. [14]
A feral population was detected in San Diego, California, in the 1980s and subsequently eradicated. [15]
These white-eyes are sociable, forming flocks which only separate on the approach of the breeding season. They are highly arboreal and only rarely descend to the ground. The breeding season is February to September but April is the peak breeding season [16] and the compact cup nest is a placed like a hammock on the fork of a branch. The nest is made of cobwebs, lichens and plant fibre. The nest is built in about 4 days and the two pale blue eggs [16] are laid within a couple of days of each other. The eggs hatch in about 10 days. Both sexes take care of brooding the chicks which fledge in about 10 days. [17]
Though mainly insectivorous, the Indian white-eye will also eat nectar and fruits of various kinds. [18]
They call frequently as they forage and the usual contact call is a soft nasal cheer. [6] They pollinate flowers when they visit them for flower insects (such as thrips) and possibly nectar (questioned) [19] that form their diet. [20] The forehead is sometimes coloured by pollen leading to mistaken identifications. [21] They have been observed bathing in dew accumulated on leaves. [22]
When nesting, they may mob palm squirrels but being small birds they are usually on the defensive. Their predators include bats (esp. Megaderma lyra ) [23] and birds such as the white-throated kingfisher. [24] Endoparasitic Haemosporidia of the genus Haemoproteus and Dorisa have been isolated from the species although these rarely cause death. [25] [26]
Like some other white-eyes, [27] they sometimes steal nest material from the nests of other birds. [28] Cases of interspecific feeding have been noted with white-eyes feeding the chicks of a paradise flycatcher. [29] [30]
Although not strong fliers, they are capable of dispersing in winds and storms to new areas including offshore islands. [13] A feral population of this species established itself in California during the 1980s requiring their capture and destruction. They were captured by luring them using call playback and live decoys into mistnets. [20]
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, as well as behavior, at least to some degree, to other Accipiter species including the Chinese goshawk, Eurasian 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 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.
The white-throated kingfisher also known as the white-breasted kingfisher is a tree kingfisher, widely distributed in Asia from the Sinai east through the Indian subcontinent to China and Indonesia. This kingfisher is a resident over much of its range, although some populations may make short distance movements. It can often be found well away from water where it feeds on a wide range of prey that includes small reptiles, amphibians, crabs, small rodents and even birds. During the breeding season they call loudly in the mornings from prominent perches including the tops of buildings in urban areas or on wires.
The black eagle is a bird of prey. 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.
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 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.
The pied bush chat is a small passerine bird found ranging from West Asia and Central Asia to the Indian subcontinent and Southeast Asia. About sixteen subspecies are recognized through its wide range with many island forms. It is a familiar bird of countryside and open scrub or grassland where it is found perched at the top of short thorn trees or other shrubs, looking out for insect prey. They pick up insects mainly from the ground, and were, like other chats, placed in the thrush family Turdidae, but are now considered as Old World flycatchers.
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 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 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 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 Oriental magpie-robin is a small passerine bird that was formerly classed as a member of the thrush family Turdidae, but now considered an Old World flycatcher. They are distinctive black and white birds with a long tail that is held upright as they forage on the ground or perch conspicuously. Occurring across most of the Indian subcontinent and parts of Southeast Asia, they are common birds in urban gardens as well as forests. They are particularly well known for their songs and were once popular as cagebirds.
The Kashmir flycatcher is a small passerine bird in the flycatcher family Muscicapidae. It breeds in the Northwest Himalayas and winters in southern India and Sri Lanka. It was formerly considered to be a subspecies of the red-breasted flycatcher, Ficedula parva, which is its closest living relative. Males are distinctive in having a blackish border to the reddish throat while the females can easily be confused with those of F. parva.
The Indian blue robin is a small bird found in the Indian Subcontinent. Formerly considered a thrush, it is now considered one of the Old World flycatchers in the family Muscicapidae. It was earlier also called the Indian blue chat. It is migratory, breeding in the forests along the Himalayas of Nepal, India, Myanmar and Bangladesh. They winter in the hill forests of the Western Ghats of India and in Sri Lanka.
The Indian paradise flycatcher is a medium-sized passerine bird native to Asia, where it is widely distributed. As the global population is considered stable, it has been listed as Least Concern on the IUCN Red List since 2004. It is native to the Indian subcontinent, Central Asia and Myanmar.
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 gray junglefowl, also known as Sonnerat's junglefowl, is one of the wild ancestors of the domestic chicken together with the red junglefowl and other junglefowls.
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 a black francolin female 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.
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.
