The pied bush chat (Saxicola caprata) 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.
They nest in cavities in stone walls or in holes in an embankment, lining the nest with grass and animal hair. The males are black with white shoulder and vent patches whose extent varies among populations. Females are predominantly brownish while juveniles are speckled.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the pied bush chat in his Ornithologie based on a specimen collected from the island of Luzon in the Philippines. He used the French name Le traquet de l'Isle de Luçon and the Latin Rubetra Lucionensis. [2] Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. [3] When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. [3] One of these was the pied bush chat. Linnaeus included a brief description, coined the binomial name Motacilla caprata and cited Brisson's work. [4] The specific epithet caprata is from a local name in Luzon which according to Brisson was Maria-capra. [2] [5] This species is now placed in the genus Saxicola that was introduced by the German naturalist Johann Matthäus Bechstein in 1802. [6] There are 16 recognised subspecies. [7]
At 13 cm (5.1 in), the pied bush chat is slightly smaller than the Siberian stonechat, Saxicola maurus, although it has a similar dumpy structure and upright stance. The male is black except for a white rump, wing patch and lower belly. The iris is dark brown, the bill and legs black. The female is drab brown and slightly streaked. Juveniles have a scaly appearance on the underside but dark above like the females.
A number of geographic populations have been given subspecies status:
Some of these isolated populations are found on islands and they include:
This species is closely related to the European-African stonechat complex. [13] S. c. fruticola from Indonesia (Moyo Island population appeared to be well differentiated from specimens from Lembata Island with a divergence estimated to about 360,000 years ago.), S. c. pyrrhonota from West Timor (Indonesia). [14]
Local names include Kala pidda in Hindi Shyama in Gujarati Kavda gapidda in Marathi Kallu kuruvi in Tamil, Kampa nalanchi in Telugu. [15] The Fore people of New Guinea called it pobogile. [16] They were once popular in Bengal as cage birds. [17] They are still found in the local bird trade of some parts of Southeast Asia. [18]
The pied bush chat is a resident breeder in tropical southern Asia from the Greater Middle East through the Indian subcontinent eastwards to Indonesia. They colonized Papua New Guinea around 1950. [19] It is found in open habitats including scrub, grassland and cultivation.
Some populations are partially migratory. A ringed individual of subspecies rossorum has been recovered from Israel. [20] The populations in India also appear to show seasonal movements but the patterns are unclear. Subspecies bicolor is found in peninsular India in winter. [21] In Karwar on the western coast, it is said to appear in October and stay till May but not seen during the rainy season. [22] Said to be absent in the Baroda district of Gujarat from April to September. [23] [24] Claud Buchanan Ticehurst noted that it was a summer visitor to Baluchistan leaving in October and further that the birds from Baluchistan were indistinguishable from rossorum of Turkestan. [24]
The breeding season is mainly February to August with a peak in March to June. Males sing from prominent perches. The whistling call is somewhat like that of an Indian robin and has been transcribed as we are tea for two with tea at higher note. The nest is built in a hole in a wall or similar site lined with grass and hair, and two to five eggs are laid. [8] Paired males did not reduce their dawn singing behaviour when their mates were trapped and temporarily excluded from the territory. This study suggests that males use dawn chorus to mediate social relationships with neighbouring males to proclaim an established territory. [25] The eggs are small and broadly oval with pale bluish-white or pinkish ground colour and speckles and blotches towards the broad end. They measure about 0.67 by 0.55 inches (1.7 by 1.4 cm). [10] Eggs are incubated chiefly by the female for 12 to 13 days. [21]
Brood parasitism by the common cuckoo (race bakeri) has been noted to be common in the Shan State of Burma, with the cuckoo visiting the nest at dusk and removing an egg before quickly laying its own. [26] [27] The female has dark brown upperparts and rufous underparts and rump. She has no white wing patches. Juveniles are similar to females. Males display during the breeding season by splaying the tail, fluttering and puffing up the white scapular feathers. [10]
This species is insectivorous, and like other chats hunts from a prominent low perch. They have been noted to feed on Pyralid moths and whitefly. [28] [29]
Nematode parasites in the genus Acuaria have been noted. [30] [31] Adult birds have few predators although bats ( Megaderma lyra ) [32] [33] and wintering Asio flammeus have been noted [34] to prey on them.
Among the Toda people in the Nilgiris, the pied bushchat or kāŗpiłc, is a bird of omen and the origin of its white wing patches is described in a story of a dairy priest Piu.f who in the ritual of churning milk forgot to remove the churning stick before fetching water from a stream. The bird attempted to obstruct him by blocking his path but he disregarded it and flicked off butter from his hands. The white spots remained but Piu.f met his death. The Kotas of the Nilgiris have an origin story to explain the sexual dimorphism of the pied bushchat but they consider the "karyvaky" bird to be one that foretells good omen. [35] The Kalam people of Papua New Guinea consider the birds as divine messengers. [36]
The brahminy kite, also known as the red-backed sea-eagle in Australia, is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors, such as eagles, buzzards, and harriers, all found in the Indian subcontinent, Southeast Asia, and Australia. The brahminy kite is found mainly on the coast and in inland wetlands, where it feeds on dead fish and other prey. Adults have a reddish-brown body plumage contrasting with their white head and breast which make them easy to distinguish from other birds of prey.
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 pied thrush is a member of the thrush family found in India and Sri Lanka. The males are conspicuously patterned in black and white while the females are olive brown and speckled. They breed in the central Himalayan forests and winter in the hill forests of southern India and Sri Lanka. Like many other thrushes, they forage on leaf litter below forest undergrowth and fly into trees when disturbed and sit still making them difficult to locate.
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 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 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 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 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.
Saxicola, the stonechats or chats, is a genus of 15 species of small passerine birds restricted to the Old World. They are insectivores occurring in open scrubland and grassland with scattered small shrubs.
The African stonechat or common stonechat is a species of the Old World flycatcher family (Muscicapidae), inhabiting sub-Saharan Africa and adjacent regions. Like the other chats, it was long assigned to the thrush family (Turdidae), to which the chats are convergent. Its scientific name refer to its appearance and habitat and means "collared rock-dweller": Saxicola from Latin saxum ("rock") + incola, torquatus, Latin for "collared".
The Nilgiri wood pigeon is large pigeon found in the moist deciduous forests and sholas of the Western Ghats in southwestern India. They are mainly frugivorous and forage in the canopy of dense hill forests. They are best identified in the field by their large size, dark colours and the distinctive checkerboard pattern on their nape.
The Indian pied myna is a species of starling found in the Indian subcontinent. It is usually found in small groups mainly on the plains and low foothills. It is often seen within cities and villages although it is not as bold as the common myna. It produces a range of calls made up of liquid notes.
The painted bush quail is a species of quail found in the hill forests of India. They move in small coveys on hillsides and are distinguished by their red bills and legs. They have a liquid alarm call and small groups will run in single file along paths before taking flight when flushed.
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 white-browed bush chat, also known as Stoliczka's bushchat, is an Old World flycatcher in the genus Saxicola. The alternative name is after the discoverer, geologist and explorer Ferdinand Stoliczka.
The Réunion stonechat is a species of stonechat, endemic to the island of Réunion. This small passerine bird is common in clearings and open mountain bushlands there up to 2600 metres above sea level, including in the plains around Piton de la Fournaise.
The Madagascar stonechat is a species of stonechat, endemic to Madagascar. It is a small bird, closely similar to the African stonechat in both plumage and behaviour, but distinguished from it by the more extensive black on the throat and minimal orange-red on the upper breast of the males.
