The streak-throated swallow or the Indian cliff swallow (Petrochelidon fluvicola) is a passerine bird, which includes a large number of other species including many swallows. It is native of South Asia where it is a breeder, year-round resident or winter visitor in the countries of Afghanistan, India, Nepal and Pakistan. It occurs as a vagrant in the Maldives, Sri Lanka, and the Middle East. [1]
The streak-throated swallow was first identified by the English zoologist Edward Blyth in 1855. It is currently placed in the genus Petrochelidon, identified by the German ornithologist Jean Cabanis in 1850. A synonym is Hirundo fluvicola. It belongs to the family Hirundinidae, named by the French polymath Constantine Samuel Rafinesque in 1815. [2]
The streak-throated swallow is a sparrow-sized bird about 11 cm (4.3 in) in length. It has a dull chestnut forehead and crown. The underparts are whitish, the upper feathers are steel-blue. The rump is pale brown and the tail has a square end. The brown streaks on the throat and chest are distinctive and used to differentiate from other similar birds. On cold mornings, large flocks are seen closely-packed on electric wires to catch the early sun. Its voice is a twittering chirp while perched. In flight, it utters a sharp trr-trr. [3] [4]
The streak-throated swallow is a year-round resident in much of South Asia. It is found from the plains of Pakistan east along the base of the Himalayas to Sikkim. The range extends southwards through the Indian peninsula up to Point Calimere in the Indian state of Tamil Nadu. It is found in large colonies in cultivated fields and open areas near ponds, lakes, canals and rivers. [3] [4]
The diet consists of midges and other tiny winged insects which are caught in the air. The nesting season is almost year round, from December to April and July to October. The birds build large colonial nests of mud. They consist of many pot-like nests fused together. Entrance to each nest is via a short tube. [3]
Flocks of streak-throated sparrows appear to be attached to specific locations. This may be influenced by proximity to sources of food. In a college in Rajasthan, India, a flock of streak-throated swallows had built a nest colony about 9 m (30 ft) above the ground, under the roof. The nests were destroyed during renovation of the building in October 2010. Within 4 days, the birds started to rebuild the nests and they completed the colony within 4 months. Every year, despite destruction of their nests during cleaning of the building, the flock returned to the same site and rebuilt the nesting colony. [5]
The sand martin, also known as the bank swallow, collared sand martin, or common sand martin, is a migratory passerine bird in the swallow family. It has a wide range in summer, embracing practically the whole of Europe and the Mediterranean countries and across the Palearctic to the Pacific Ocean. It is a Holarctic species also found in North America. It winters in eastern and southern Africa, South America, and the Indian Subcontinent.
The swallows, martins, and saw-wings, or Hirundinidae, are a family of passerine songbirds found around the world on all continents, including occasionally in Antarctica. Highly adapted to aerial feeding, they have a distinctive appearance. The term "swallow" is used colloquially in Europe as a synonym for the barn swallow. Around 90 species of Hirundinidae are known, divided into 19 genera, with the greatest diversity found in Africa, which is also thought to be where they evolved as hole-nesters. They also occur on a number of oceanic islands. A number of European and North American species are long-distance migrants; by contrast, the West and South African swallows are nonmigratory.
The Eurasian crag martin or just crag martin is a small passerine bird in the swallow family. It is about 14 cm (5.5 in) long with ash-brown upperparts and paler underparts, and a short, square tail that has distinctive white patches on most of its feathers. It breeds in the mountains of southern Europe, northwestern Africa and across the Palearctic. It can be confused with the three other species in its genus, but is larger with brighter tail spots and different plumage tone. Many European birds are resident, but some northern populations and most Asian breeders are migratory, wintering in northern Africa, the Middle East or India.
The cliff swallow or American cliff swallow is a member of the passerine bird family Hirundinidae, the swallows and martins. The generic name Petrochelidon is derived from Ancient Greek petros meaning "rock" and khelidon "swallow", and the specific name pyrrhonota comes from purrhos meaning "flame-coloured" and -notos "-backed".
The Pacific swallow is a small passerine bird in the swallow family. It breeds in tropical southern Asia and the islands of the south Pacific. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. The hill swallow and the welcome swallow were formerly considered conspecific.
The hill swallow is a small passerine bird in the swallow family. It breeds in southern India and Sri Lanka. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. It was formerly considered to be a subspecies of the Pacific swallow.
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 crested treeswift is a species of tree swift. It was for some time considered the same species as its eastern relative, the gray-rumped treeswift, but they do not interbreed where their ranges overlap. It is distinct in flight, with long, bowed wings and a deeply forked tail that usually appears narrow and pointed.
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 painted stork is a large wader in the stork family. It is found in the wetlands of the plains of tropical Asia south of the Himalayas in the Indian Subcontinent and extending into Southeast Asia. Their distinctive pink tertial feathers of the adults give them their name. They forage in flocks in shallow waters along rivers or lakes. They immerse their half open beaks in water and sweep them from side to side and snap up their prey of small fish that are sensed by touch. As they wade along they also stir the water with their feet to flush hiding fish. They nest colonially in trees, often along with other waterbirds. The only sounds they produce are weak moans or bill clattering at the nest. They are not migratory and only make short distance movements in some parts of their range in response to changes in weather or food availability or for breeding. Like other storks, they are often seen soaring on thermals.
The cave swallow is a medium-sized, squarish-tailed swallow belonging to the same genus as the more familiar and widespread cliff swallow of North America. The cave swallow, also native to the Americas, nests and roosts primarily in caves and sinkholes.
Ranganathittu Bird Sanctuary, is a bird sanctuary in the Mandya District of Karnataka in India. It is the largest bird sanctuary in the state, 40 acres (16 ha) in area, and comprises six islets on the banks of the Kaveri river. The sanctuary has been designated on 15 February 2022 as a protected Ramsar site since 2022.
The Malabar barbet is an Asian barbet native to the Western Ghats in India. It was formerly treated as a race of the crimson-fronted barbet. It overlaps in some places with the range of the coppersmith barbet and has a similar but more rapid call.
The dusky crag martin is a small passerine bird in the swallow family. It is about 13 cm (5 in) long with a broad body and wings, and a short square tail that has small white patches near the tips of most of its feathers. This martin has sooty-brown upperparts and slightly paler underparts. The two subspecies are resident breeding birds in South Asia from the Indian subcontinent to southwestern China and the northern parts of Thailand, Vietnam and Laos.
The black-breasted weaver, also known as the Bengal weaver or black-throated weaver, is a weaver resident in the northern river plains of the Indian subcontinent. Like the other weavers, the males build an enclosed nest from reeds and mud, and visiting females select a mate at least partially based on the quality of the nest.
The crag martins are four species of small passerine birds in the genus Ptyonoprogne of the swallow family. They are the Eurasian crag martin (P. rupestris), the pale crag martin (P. obsoleta), the rock martin (P. fuligula) and the dusky crag martin (P. concolor). They are closely related to each other, and have formerly sometimes been considered to be one species. They are closely related to the Hirundo barn swallows and are placed in that genus by some authorities. These are small swallows with brown upperparts, paler underparts without a breast band, and a square tail with white patches. They can be distinguished from each other on size, the colour shade of the upperparts and underparts, and minor plumage details like throat colour. They resemble the sand martin, but are darker below, and lack a breast band.
The tree martin is a member of the swallow family of passerine birds. It breeds in Australia, mostly south of latitude 20°S and on Timor island. It is migratory, wintering through most of Australia, New Guinea, Indonesia east of the Wallace Line and the Solomon Islands. It is a vagrant to New Zealand, where it has bred, and New Caledonia. This species is frequently placed in the genus Hirundo as Hirundo nigricans.
The fairy martin is a member of the swallow family of passerine birds which breeds in Australia. It is migratory wintering through most of Australia, with some birds reaching New Guinea and Indonesia. It is increasingly a wanderer to New Zealand, where it may have bred. This species is frequently placed in the genus Hirundo as Hirundo ariel.
