[AdSense-A] Potoos (family Nyctibiidae) are a group of near passerine birds related to the nightjars and frogmouths. They are sometimes called Poor-me-ones, after their haunting calls. There are seven species in one genus, Nyctibius, in tropical Central andSouth America. These are nocturnal insectivores which lack the bristles around the mouth found in the true nightjars. They hunt from a perch like a shrike or flycatcher. During the day they perch upright on tree stumps, camouflaged to…
The Common Sunbird-Asity or Sunbird Asity (Neodrepanis coruscans) is a species of bird in the Philepittidae family. It is endemic to Madagascar. Its natural habitat is subtropical or tropical moist lowland forests
The Bornean Bristlehead (Pityriasis gymnocephala), also variously known as the Bristled Shrike, Bald-headed Crow or the Bald-headed Wood-Shrike, is the only member of the passerine family Pityriaseidae and genus Pityriasis. It is an enigmatic and uncommon species of the rainforest canopy of the island of Borneo,[2] to which it is endemic. The Bristlehead is a medium-sized (25 centimetres (9.8 in) in length) black or dark grey bird, with red thighs and a red head, throat and neck, with grey ear-coverts and a featherless yellow crown. There is a white wing-patch, visible in flight, and females also have red spots on the flanks. It has a massive heavy black hooked bill and a short tail, giving it a chunky appearance. The crown is covered by short (3–4 mm) yellow or straw-coloured skin projections like bare feather shafts, hence the name ‘Bristlehead’. Juveniles have black thighs, red ear-coverts, a red eye-ring, just a few red feathers on the head and undeveloped ‘bristles’. It is a noisy species making a variety of unmusical calls, including distinctive high-pitched nasal whining notes interspersed with harsher notes, chattering noises, whistles, honks and chortles.
The Banded Woodpecker (Picus miniaceus) is a species of bird in the Picidae family. It is found in Brunei, Indonesia, Malaysia, Myanmar, Singapore, and Thailand. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical mangrove forests. This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
The Black-and-orange Flycatcher (Ficedula nigrorufa) is a species of flycatcher endemic to the central and southern Western Ghats, the Nilgiris and Palni hill ranges in southern India. It is unique among the Ficedula flycatchers in having rufous coloration on its back and prior to molecular studies was suggested to be related to the chats and thrushes. A distinctly coloured bird found mainly in the high-elevation areas of the Western Ghats, the Nilgiris, the Palnis and associated hill ranges. The male is distinctly black headed with black wings. The female has the black replaced by dark brown and has a light eye-ring. They are usually seen singly or in pairs. The young bird at around two weeks of age is brownish orange with a whitish vent and abdomen. The head has dark streaks and the wings appear bluish with a trace of brown. There is a pale ring around the eye and the orange tail appears stumpy. Eight weeks after fledging they appear almost like adults except for patches of brown feathers in the crown. The main population of this bird is found in the high elevation plateaus (above 1500m) areas of the Nilgiris, Palani Hills, Biligirirangans (Bellaji and Honnametti) and Kannan Devan Hills. They prefer areas with high leaf litter and undergrowth in open shola grassland habitats. The density was about 2.8 ha per pair during the breeding season. It is a highly parochial bird and no local movements other than dispersal of young has been noted.[6] To the north, it occurs in the Kudremukh National Park and the Bababudan Hills and south to the Ashambu Hills.[7] Some old records of the species from Maharashtra and Sri Lanka[8] have been considered dubious.
The Malabar Grey Hornbill (Ocyceros griseus) is a hornbill that is endemic to the Western Ghats and associated hills of southern India. They have a large beak but lack the casque that is prominent in other species of hornbills. They are found mainly in dense forest and around rubber, arecanut or coffee plantations.[2] They move around in small groups, feeding on figs and other forest fruits. Their loud cackling and laughing call makes them familiar to people living in the region. The Malabar Grey Hornbill is a large bird and mid-sized hornbill, at 45 to 58 cm (18 to 23 in) in length with a 23 cm (9.1 in) tail and pale or yellowish to orange bill.[3] Males have a reddish bill with a yellow tip while the females have a plain yellow bill with black at the base of the lower mandible and a black stripe along the culmen. They show a broad whitish superciliary band above the eye running down to the neck. They fly with a strong flap and glide flight and hop around heavily on the outer branches of large fruiting trees. They has brown-grey wings, a white carpal patch and black primary flight feathers tipped with white. The Indian Grey Hornbill which is found mainly on the adjoining plains is easily told apart by its prominent casque and in flight by the white trailing edge to the entire wing. The Malabar Grey Hornbill has a grey back, and a cinnamon vent. The long tail is blackish with a white tip, and the underparts are grey with white streaks. The long curved bill has no casque. Immature birds have browner upperparts and a yellow bill.[4] Young birds have a dull white or yellow iris. Their loud calls are distinctive and include “hysterical cackling”, “laughing” and “screeching” calls. The Malabar Grey Hornbill is a common resident breeder in the Western Ghats and associated hills of southern India. They are mainly found in dense forest habitats and the thinner dry forest habitat of the plains is typically occupied by the Indian Grey Hornbill. In the past the Sri Lanka Grey Hornbill was included with this species but is now considered distinct.
The Greater Racket-tailed Drongo (Dicrurus paradiseus) is a medium-sized Asian bird which is distinctive in having elongated outer tail feathers with webbing restricted to the tips. They are placed along with other drongos in the family Dicruridae. They are conspicuous in the forest habitats often perching in the open and by attracting attention with a wide range of loud calls that include perfect imitations of many other birds. It has been suggested that these imitations may help in the formation ofmixed-species foraging flocks, a feature seen in forest bird communities where many insect feeders forage together. These drongos will sometimes steal insect prey caught or disturbed by other foragers in the flock. They are diurnal but are active well before dawn and late at dusk. Owing to their widespread distribution and distinctive regional variation, they have become iconic examples of speciation by isolation and genetic drift.
In most of its range in Asia, this is the largest of the drongo species and is readily identifiable by the distinctive tail rackets and the crest of curled feather that begin in front of the face above the beak and along the crown to varying extents according to the subspecies. The tail with twirled rackets is distinctive and in flight it can appear as if two large bees were chasing a black bird. In the eastern Himalayas the species can be confused with the Lesser Racket-tailed Drongo, however the latter has flat rackets with the crest nearly absent. This widespread species includes populations that have distinct variations and several subspecies have been named. The nominate form is found in southern India, mainly in forested areas of the Western Ghats and the adjoining hill forests of peninsular India. The subspecies in Sri Lanka is ceylonicus and is similar to the nominate form but slightly smaller. The subspecies found along the Himalayas is grandisand is the largest and has long glossy neck hackles. The Andaman Islands form otiosus has shorter neck hackles and the crest is highly reduced while the Nicobars Island form nicobariensis has a longer frontal crest and with smaller neck hackles than otiosus.[3] The Sri Lanka Drongo D. lophorinus used to be treated as a subspecies due to the suggestion that it formed hybrids with ceylonicus is considered a separate species in newer taxonomic treatments on the basis of their overlapping ranges.[3][4] Specimens of the nominate form have sometimes been confused with lophorinus.[5] Considerable variation in shape of the bill, extent of the crest, hackles and tail rackets exists in the island populations of Southeast Asia. The Bornean brachyphorus (=insularis), banguey of Banggai lack crests (banguey has frontal feathers that arch forwards) while very reduced crests are found in microlophus (=endomychus; Natunas, Anambas and Tiomans) and platurus (Sumatra). A number of forms are known along the Southeast Asian islands and mainland including formosus (Java), hypoballus (Thailand), rangoonensis (northern Burma, central Indian populations were earlier included in this) and johni (Hainan). Young birds are duller, and can lack a crest while moulting birds can lack the elongate tail streamers. The racket is formed by the inner web of the vane but appears to be on the outer web since the rachis has a twist just above the spatula.
The Victoria’s Riflebird (Ptiloris victoriae) also known as Duwuduwu to the local Aboriginal people, is a bird of paradise endemic to the Atherton Tableland region of northeastern Queensland, Australia where it resides year-round. The smallest riflebird, it measures between 23–25 cm. Males have an iridescent purple sheen plumage, which becomes more blue-green on the head and more bronze on the lower breast. The throat is velvety black with a metallic green and blue triangular patch in the center. Females have a pale eyebrow, and the buff underparts are faintly barred with brown. The call is a loud “years”. As well as insects, they eat fruits from the trees, some which they peel by holding the fruit with one foot and removing the skin with their bill. The Victoria’s Riflebird was discovered by John Macgillivray for John Gould in 1848 and is named after Queen Victoria of the United Kingdom. A common species in its limited range, the Victoria’s Riflebird is evaluated as Least Concern on the IUCN Red List of Threatened Species.[1] It is listed on Appendix II of CITES. When the male begins to display, he erects the feathers of his throat and sides to accentuate the bright colours of his plumage in the shafts of sunlight that pierce the dimness of the rainforest. He curves his rounded wings above his body and tilts his head back to expose his chin and throat to the light, and then moves from side to side in a fashion that looks almost mechanical. The female is attracted to the male’s display post by his raspy ‘yaars’ call, which becomes softer and more tuneful during the display. The pair then face each other closely, and each bird raises and extends its wings forward alternately in an increasingly rapid rhythm. Finally the male embraces the female with both wings, and copulation ensues.
[AdSense-A] The Taiwan Blue Magpie (Urocissa caerulea), also called the Taiwan Magpie or Formosan Blue Magpie (Chinese: 臺灣藍鵲; pinyin: Táiwān lán què) or the “long-tailed mountain lady” (Chinese: 長尾山娘; pinyin: Chángwěi shānniáng;Taiwanese: Tn̂g-boé soaⁿ-niû), is a member of the Crow family. It is an endemic species living in the mountains of Taiwan at elevations of 300 to 1200m. In the 2007 National Bird Voting Campaign held by the Taiwan International Birding Association,[3] there were over…
The Magpie Tanager (Cissopis leveriana) is a South American species of tanager. It is the only member of the monotypic genus Cissopis. As suggested by its common name, this blue-black and white species is superficially reminiscent of a European Magpie. With a total length of 25–30 cm (10–12 in), a large percentage of which is tail, it is the longest species of tanager. It weighs 69-76 g. It is widespread in humid tropical and subtropical woodland, plantations, second growth, and parks in South America east of the Andes. It is absent from drier regions (e.g. the Caatinga) and most of north-eastern Brazil. In densely forested regions, it mainly occurs in relatively open sections (e.g. near major rivers). In such regions it is spreading with deforestation, which opens up the habitat. It is largely restricted to lowlands, but occurs up to an altitude of 2000 m (6500 ft) on the east Andean slopes. It is common throughout most of its range, but rarer in the Guianas. Typically occurs in conspicuous, noisy pairs or groups of up to 10 individuals. Commonly takes part in mixed-species flocks. Often moves long tail up and down. Eats seed, fruits and insects. The cup-shaped nest is lined with grass, leaves or other plant materials and is located low in trees near the ground or in shrubs in dense vegetation. The 2 eggs are reddish-brown with brown spots. The incubation time is 12–13 days in captivity. The binomial name commemorates the English collector Sir Ashton Lever.
