Hypocolius ampelinus | |
The grey hypocolius [3] or simply hypocolius (Hypocolius ampelinus) is a small passerine bird species. It is the sole member of the genus Hypocolius and it is placed in a family of its own, the Hypocoliidae. This slender and long tailed bird is found in the dry semi-desert region of northern Africa, Arabia, Afghanistan, Pakistan, and western India. They fly in flocks and forage mainly on fruits, migrating south in winter. During Migration mainly found Fruit eating on Salvadora persica .
The grey hypocolius is a slim bird with a long tail, slight crest and thick, short hook-tipped bill. Its shape and soft, satiny plumage resembles that of the waxwing. Birds are mainly a uniform grey or brownish-grey colour, with males having a black triangular mask around the eyes. They have white-tipped black primary wing feathers and a black terminal band on the tail. Adults are about 19–21 cm (7.5–8.3 in) in length. [4]
The head feathers are raised when the bird is excited. They fly in a straight non-undulating style and when hopping in shrubbery, can appear like a babbler. The tarsus is short and sturdy with coarse scales. There are rictal bristles visible at the base of the bill and the nostrils are exposed, small and oval. [5]
The relationships of the species were formerly unclear. Earlier authors had suggested that they were related to the bulbuls [6] or shrikes. [7] [8] They appear to be related to the waxwings, and at least one study based on molecular sequences suggests that it belongs to the same group. [9] [10] A 2019 study found them to be in a clade containing the palmchat (Dulidae), waxwings (Bombycillidae), silky-flycatchers (Ptiliogonatidae), hylocitrea (Hylocitreidae), and the extinct Hawaiian honeyeaters (Mohoidae), with Hypocoliidae being a sister group to the Mohoidae (with both diverging about 15-20 mya during the early-mid Miocene), and the clade containing Mohoidae and Hypocoliidae being sister to Hylocitreidae, which diverged slightly earlier in the Miocene. [11]
The grey hypocolius ranges through the Middle East, breeding in the Iraq, Iran, Afghanistan, Pakistan, Turkmenistan area, [12] and wintering mostly near the Red Sea and Persian Gulf coasts of Arabia, including Bahrain. It is a vagrant to Turkey, Israel, Egypt and Oman. They are regular winter visitors to the Kutch and Jamnagar region of western India [13] [14] and vagrants have been noted as far south as Kihim near Bombay. [15] It is found in woodland and scrub in arid and semiarid regions, especially river valleys near deserts, as well as in irrigated and cultivated areas with trees, sea costal area, palm groves and gardens. [6] [16]
The grey hypocolius is a shy and unobtrusive, even cryptic, bird which will fly to thick cover when disturbed, where it will remain motionless until the perceived danger has passed. Its flight is strong and direct (without undulations). [4] It will form flocks, especially in winter, and roost communally. [16]
The breeding season is June or July in Arabia. The nest is cup shaped and deep lined with hair and fluff. The nest is often placed on the leaves of a date palm at a height of about 3 to 5 feet. Both the male and female take part in nest building. The clutch is four eggs. The eggs are leaden white with blotches. [17] The incubation period is about 14–15 days. [18]
Grey hypocoliuses forage quietly and methodically in foliage, through clusters of trees, palm groves and orchards, rarely coming to the ground. Though they may eat some insects, their main diet consists of fruits and berries, including Real mustard fruits, mulberries, figs and dates. In captivity they have been known to readily take bread. [19]
The most common vocalization is a series of squealing descending notes or kleeeu whistles. Other calls include scolding chirps. [4]
Because the species has a large range, and because it does not meet the population size and decline criteria of the IUCN Red List, the conservation status is evaluated as being of "least concern". [1] Because of its monotypic family status it is much sought after by birdwatchers. [20]
The waxwings are three species of passerine birds classified in the genus Bombycilla. They are pinkish-brown and pale grey with distinctive smooth plumage in which many body feathers are not individually visible, a black and white eyestripe, a crest, a square-cut tail and pointed wings. Some of the wing feathers have red tips, the resemblance of which to sealing wax gives these birds their common name. According to most authorities, this is the only genus placed in the family Bombycillidae, although sometimes the family is extended to include related taxa that are more usually included in separate families: silky flycatchers, Hypocolius (Hypocoliidae), Hylocitrea (Hylocitreidae), palmchats (Dulidae) and the Hawaiian honeyeaters (Mohoidae). There are three species: the Bohemian waxwing, the Japanese waxwing and the cedar waxwing.
The Bohemian waxwing is a starling-sized passerine bird that breeds in the northern forests of the Palearctic and North America. It has mainly buff-grey plumage, black face markings and a pointed crest. Its wings are patterned with white and bright yellow, and some of the wing feathers have red tips, the resemblance of which to sealing wax gives these birds their common name. The three subspecies show only minor differences in appearance. Females are similar to males, although young birds are less well-marked and have few or no waxy wingtips. Although the Bohemian waxwing's range overlaps those of the cedar and Japanese waxwings, it is easily distinguished from them by size and plumage differences.
The Asian green bee-eater, also known as little green bee-eater, and green bee-eater in Sri Lanka, is a near passerine bird in the bee-eater family. It is resident but prone to seasonal movements and is found widely distributed across Asia from coastal southern Iran east through the Indian subcontinent to Vietnam. Populations in Africa and the Arabian Peninsula that were formerly assigned to this species are now considered distinct species: the African green bee-eater and the Arabian green bee-eater. They are mainly insect eaters and they are found in grassland, thin scrub and forest often quite far from water. Several regional plumage variations are known and several subspecies have been named.
The brown shrike is a bird in the shrike family that is found mainly in Asia. It is closely related to the red-backed shrike and isabelline shrike. The genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. The specific cristatus is Latin for "crested", used in a broader sense than in English. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.
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 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 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 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 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 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.
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 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 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 woodswallow, sometimes also called the ashy swallow-shrike, is a woodswallow which is found in south Asia. Like other woodswallows, it has a short curved bill, a short square tail and long wings. It is usually seen perched in groups, high on powerlines, tall bare trees and most often in areas with a predominance of tall palm trees.
The yellow-throated bulbul is a species of songbird in the bulbul family of passerine birds. The species 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.
The hylocitrea, also known as the yellow-flanked whistler or olive-flanked whistler, is a species of bird that is endemic to montane forests on the Indonesian island of Sulawesi. It is monotypic within the genus Hylocitrea, and has traditionally been considered a member of the family Pachycephalidae, but recent genetic evidence suggests it should be placed in a monotypic subfamily of the family Bombycillidae, or even its own family, Hylocitreidae. A 2019 study found it to be a sister group to a clade containing the hypocolius (Hypocoliidae) and the extinct Hawaiian honeyeaters (Mohoidae), with the clade containing all three being a sister group to the silky-flycatchers (Ptiliogonatidae). The divergences forming these families occurred in the early Miocene, about 20-23 million years ago.
Mohoidae, also known as the Hawaiian honeyeaters, was a family of Hawaiian species of now recently extinct, nectarivorous songbirds in the genera Moho (ʻōʻō) and Chaetoptila (kioea). These now extinct birds form their own family, representing the only complete extinction of an entire avian family in modern times, when the disputed family Turnagridae is regarded as invalid. The last surviving species in the family, the Kauai O'o, became extinct after 1987.
