The jungle nightjar (Caprimulgus indicus) is a species of nightjar found in the Indian Subcontinent. It is found mainly on the edge of forests where it is seen or heard at dusk. The taxonomy of this and related nightjars is complex and a range of treatments have been followed that cover this and several other nightjars in the Asian region. It was formerly called the grey nightjar or Indian jungle nightjar and sometimes included the East Asian grey nightjar (C. jotaka) as a subspecies.

The jungle nightjar is about 21–24 cm long with the Sri Lankan population (ssp. kelaarti) being smaller. Mostly grey with black streaks on the crown, it lacks a conspicuous wing patch which is rufous. The tail is greyish with well separated narrow black bars. The male has a white throat patch that is broken at the middle. The female has a rufous throat patch and submoustachial streaks. The usual call is a series of thacoo or chuck notes (at the rate of 5 every 2 seconds [2] ) like a distant engine. [3] The song is a slow and regular, series of FWik-m notes, repeated for as long as 10 seconds. This sometimes ends in quick whistling foo-foo with the quality of sounds obtained when air is blown over an open bottle. A call described as uk-krukroo attributed to this species by Ali and Ripley in their Handbook is in error and is the call of the Oriental scops owl (Otus sunia). [4] [5] [6]

Taxonomy

The Indian (nominate) and the Sri Lankan populations (ssp. kelaarti) are included in this species while jotaka (whose egg coloration and calls differs) has been separated and elevated to a full species, Grey nightjar, by Rasmussen and Anderton (2005). The populations found along the Himalayas, west from Hazara to Bhutan and south to Bangladesh, hazarae, are then treated as a subspecies of Caprimulgus jotaka in this work. [4] Records of jotaka have come from the Andamans and Phuentsholing. [7] [8]

Older treatments include the widely distributed (China, Japan) migratory subspecies jotaka and phalaena (Palau Island) in this species. [9] Its scientific name means "nightjar from India", and it is thus sometimes confused with C. asiaticus which is commonly known as the Indian nightjar. To distinguish them, in former times C. indicus was known as the large Indian nightjar.

Behaviour

The jungle nightjar becomes active at dusk, often over hilly grassland or scrub, perching regularly at favourite prominent bare posts or rocks. It roosts in trees, perching lengthwise along a branch. [3] [10] The breeding season in India is January to June and March to July in Sri Lanka. The nest is a bare patch on the ground in which two eggs are laid. [4] [11] Both parents incubate the eggs for about 16 to 17 days. [12]

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 to other sparrowhawk species including the Chinese 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.

<span class="mw-page-title-main">Oriental darter</span> Species of bird

The Oriental darter is a water bird of tropical South Asia and Southeast Asia. It has a long and slender neck with a straight, pointed bill and, like the cormorant, it hunts for fish while its body is submerged in water. It spears a fish underwater, bringing it above the surface, tossing and juggling it before swallowing the fish head first. The body remains submerged as it swims, and the slender neck alone is visible above the water, which accounts for the colloquial name of snakebird. Like the cormorants, it has wettable feathers and it is often found perched on a rock or branch with its wings held open to dry.

<span class="mw-page-title-main">Indian nightjar</span> Species of bird

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 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.

<span class="mw-page-title-main">Indian scimitar babbler</span> Species of bird

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 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.

They are found in dense forest, often in small groups, and can often be found perched on bare branches of tall trees rising above the forest canopy.

<span class="mw-page-title-main">Painted francolin</span> Species of bird

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.

<span class="mw-page-title-main">Bank myna</span> Species of bird

The bank myna is a myna found in the northern parts of South Asia. It is smaller but similar in colouration to the common myna, only differing in having brick-red naked skin behind the eyes instead of yellow. It is greyer on the underside and in this and in the presence of a slight tuft of feathers bears some resemblance to the jungle myna. They are found in flocks on the plains of northern and central India, often within towns and cities. Their range appears to be extending southwards into India. The name is derived from their habit of nesting almost exclusively in the earthen banks of rivers, where they excavate burrows and breed in large colonies.
