The great stone-curlew or great thick-knee (Esacus recurvirostris) is a large wader which is a resident breeder in tropical southern Asia from India, Pakistan, Sri Lanka, Bangladesh into South-east Asia.
The great stone-curlew was formally described in 1829 by the French naturalist Georges Cuvier and given the binomial name Oedicnemus recurvirostris. [2] The type locality is Nepal. [3] The specific epithet recurvirostris combines Latin recurvis meaning "bent backwards" with -rostris meaning "-billed". [4] The species is now placed in the genus Esacus that was introduced in 1831 to accommodate the great stone-curlew by the French naturalist René Lesson. [5] [6] The species is monotypic: no subspecies are recognised. [6]
The great thick-knee is a large wader at 49–55 cm, and has a massive 7 cm bill with the lower mandible with a sharp angle giving it an upturned appearance. It has unstreaked grey-brown upperparts and breast, with rest of the underparts whitish. The face has a striking black and white pattern, and the bill is black with a yellow base. The eyes are bright yellow and the legs a duller greenish-yellow. In flight, the great thick-knee shows black and white flight feathers on the upperwing, and a mainly white underwing. Sexes are similar, but young birds are slightly paler than adults.
This species prefers gravel banks along rivers or large lakes, and also beaches. It is mainly nocturnal or crepuscular like other stone-curlews, but can frequently be seen foraging during the day, moving slowly and deliberately, with occasional short runs. It tends to be wary and flies off into the distance ahead of the observer, employing powerful, rather stiff wingbeats. The call is a wailing whistle, given mainly at night, as with other birds in this family. The great thick-knee eats crabs, large insects, and other animal prey. A single egg is laid in a bare scrape on the open shingle.
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 black-winged stilt is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopussensu lato. Meanwhile, the black-necked and white-backed stilts both inhabit the Americas; the pied stilt ranges from Australasia and New Zealand. Today, most sources accept between one and four actual species.
The green sandpiper is a small wader (shorebird) of the Old World.
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 beach stone-curlew also known as beach thick-knee is a large, ground-dwelling bird that occurs in Australasia, the islands of South-east Asia. At 55 cm (22 in) and 1 kg (2.2 lb), it is one of the world's largest shorebirds.
The plum-headed parakeet is a species of parakeet in the family Psittacidae. It is endemic to the Indian Subcontinent and was once thought to be conspecific with the blossom-headed parakeet before being elevated to a full species. Plum-headed parakeets are found in flocks, the males having a pinkish purple head and the females, a grey head. They fly swiftly with twists and turns accompanied by their distinctive calls.
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.
Leptoptilos is a genus of very large tropical storks, commonly known as adjutants. The name means thin (lepto) feather (ptilos). Two species are resident breeders in southern Asia, and the marabou stork is found in Sub-Saharan Africa.

The akun eagle-owl is a species of owl in the family Strigidae and is native to the African tropical rainforest.
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.
The Indian stone-curlew or Indian thick-knee 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.
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 Bharathappuzha, also known as the Nila or Ponnani River, is a river in the Indian states of Tamil Nadu and Kerala. With a length of 209 km, it is the second longest river that flows through Kerala after the Periyar. It flows through Palakkad Gap, which is also the largest opening in the Kerala portion of Western Ghats. The Nila has groomed the culture and life of South Malabar part of Kerala. It is also referred to as the "Peraar" in ancient scripts and documents. River Bharathapuzha is an interstate river and lifeline water source for a population residing in four administrative districts, namely Malappuram and Palakkad districts, and parts of Palakkad-Thrissur district border of Kerala and Coimbatore, and Tiruppur of Tamil Nadu. The fertile Thrissur-Ponnani Kole Wetlands lie on its bank.
