The Indian stone-curlew or Indian thick-knee (Burhinus indicus) is a species of bird in the family Burhinidae. It was formerly included as a subspecies of the Eurasian stone-curlew. This species is found in the plains of South and South-eastern Asia. They have large eyes and are brown with streaks and pale marks making it hard to spot against the background of soils and rocks. Mostly active in the dark, they produce calls similar to the true curlews, giving them their names.
The Indian stone-curlew was formally described in 1866 by the Italian zoologist Tommaso Salvadori based on specimens obtained in India. He coined the binomial name Oedicnemus indicus. [2] The specific epithet is Latin meaning "Indian". [3] The Indian stone-curlew is now placed in the genus Burhinus that was erected in 1811 by the German zoologist Johann Karl Wilhelm Illiger in 1811. [4] [5] The species is monotypic: no subspecies are recognised. [5]
This species was formerly treated as a subspecies of the Eurasian stone-curlew Burhinus oedicnemus but the Indian population is distinctive in plumage, and non-migratory, leading to its being treated as a full species by Pamela Rasmussen in 2005. [6] [7] There has however been no major phylogenetic study of the genus.
This stocky and brown ground bird with large eyes is about 41 centimeters in length. It has dark streaks on a sandy brown ground colour and is plover-like. The large head has a dark stripe bordering a creamy moustachial stripe below the eye. There is also a narrow creamy supercilium. [8] The legs are stout and the knees are thick, giving them the group of name of "thick-knee". They have large yellow eyes. The sexes are alike and the immature is paler than adult with more marked buff and streaks on the underparts. In flight, they have two prominent white and a white patch on the darker primaries and at rest a broad pale band is visible on the wing. [9] [6]
The Indian stone curlew is active mainly at dawn and dusk and it calls mainly at night. The call is a series of sharp whistling notes pick-pick-pick-pick ending sometimes like pick-wick, pick-wick. They are found in small groups and during the day, they are found standing still under the shade of bush. [9]
Found in dry deciduous forests and thorn forest, scrubby riverbeds, groves and even gardens. [6] This species is restricted to Bangladesh, Bhutan, Cambodia, India, Laos, Myanmar, Nepal, Pakistan, Sri Lanka, Thailand and Viet Nam. [1] It is found in thin dry deciduous forest, scrub, stony hillsides and fallow lands. [9]
The breeding season is mainly March and April. The normal clutch is 2 to 3 stone colored eggs laid inside a scrape on bare ground, sometimes at the base of a bush. The eggs are incubate mainly by the female with male standing guard nearby. The nidifugous chicks are downy and cryptically coloured and follow the parents soon after hatching. The young chicks freeze and crouch when alarmed and the cryptic plumage makes them hard to detect. [9]
The diet mainly consists of insects, worms and small reptiles and occasionally some seeds. [9]
The stone-curlews, also known as dikkops or thick-knees, consist of 10 species within the family Burhinidae, and are found throughout the tropical and temperate parts of the world, with two or more species occurring in some areas of Africa, Asia, and Australia. Despite the group being classified as waders, most species have a preference for arid or semiarid habitats.
The bush stone-curlew or bush thick-knee is a large, ground-dwelling bird endemic to Australia. Its favoured habitat is open plains and woodlands, where it stalks slowly at night in search of invertebrates such as insects. Its grey-brown coloration is distinguished by dark streaks, its eyes are large and legs are long. It is capable of flight, but relies on the camouflage of its plumage to evade detection during the day; the bush curlew adopts a rigid posture when it becomes aware of an observer. Both sexes care for two eggs laid on the bare ground, usually sited near bush in a shaded position or next to a fallen branch.
The Eurasian stone-curlew, Eurasian thick-knee, or simply stone-curlew is a northern species of the Burhinidae (stone-curlew) bird family.
The Senegal thick-knee is a stone-curlew, a group of waders in the family Burhinidae. Their vernacular scientific name refers to the prominent joints in the long yellow or greenish legs.
The great stone-curlew or great thick-knee is a large wader which is a resident breeder in tropical southern Asia from India, Pakistan, Sri Lanka, Bangladesh into South-east Asia.
The double-striped thick-knee is a stone-curlew, a group of waders in the family Burhinidae. The vernacular name refers to the prominent joints in the long greenish-grey legs, and bistriatus to the two stripes of the head pattern.
The lesser coucal is a species of cuckoo in the family Cuculidae. It has a wide distribution range that overlaps with several other similar species. The habitat in which it is found is often marshy land with grass and tree cover. It is distinguished by its smaller size, less prominent bill, pale shaft streaks on the feathers of the head and back. It has a much longer claw on its hind toe and a distinct call. It is also among the few coucals that show season plumage differences but like in other coucals, the sexes cannot be distinguished in the field.
The Peruvian thick-knee is a species of bird in the family Burhinidae. It is found in Chile, Ecuador, and Peru. Its natural habitats are subtropical or tropical dry shrubland, subtropical or tropical seasonally wet or flooded lowland grassland, and pastureland. It is a ground-dwelling bird and feeds on insects and small animals.
Burhinus is a genus of birds in the family Burhinidae. This family also contains the genus Esacus. The genus name Burhinus comes from the Greek bous, ox, and rhis, nose.
Esacus is a genus of bird in the stone-curlew family Burhinidae. The genus is distributed from Pakistan and India to Australia. It contains two species, the great stone-curlew and the beach stone-curlew.
The brown-cheeked rail or eastern water rail is a species of bird in the family Rallidae. It breeds in northern Mongolia, eastern Siberia, northeast China, Korea and northern Japan, and winters in southeast Asia. It used to be considered a subspecies of the water rail.
