Burhinus is a genus of birds in the family Burhinidae. This family also contains the genus Esacus. [3] The genus name Burhinus comes from the Greek bous, ox, and rhis, nose. The Burhinus are commonly called thick-knee, stone-curlew or dikkop. They are medium-sized, terrestrial waders, though they are generally found in semi-arid to arid, open ...
The bush stone-curlew or bush thick-knee (Burhinus grallarius, obsolete name Burhinus magnirostris) 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.
The names thick-knee and stone-curlew are both in common use. The term stone-curlew owes its origin to the broad similarities with true curlews. Thick-knee refers to the prominent joints in the long yellow or greenish legs and apparently originated with a name coined in 1776 for B. oedicnemus, the Eurasian stone-curlew.
Most birds have four toes, typically three facing forward and one pointing backward. [7] [10] [8] In a typical perching bird, they consist respectively of 3, 4, 5 and 2 phalanges. [2] Some birds, like the sanderling, have only the forward-facing toes; these are called tridactyl feet while the ostrich have only two toes (didactyl feet).
The species name oedicnemus combines the Greek oidio meaning "to swell", and kneme meaning "shin" or "leg", referring to the bird's prominent tibiotarsal joints, [6] which also give it the common name of "thick-knee". This is an abbreviated form of Thomas Pennant's 1776 coinage "thick-kneed bustard".
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] Adult with chick crouching beside it
The spotted thick-knee, which can reach up to 45.5 cm (17.9 in) in height, has long legs and brown-and-white speckled plumage which provides camouflage, making it difficult to spot the bird in the grasslands and savannas where it roams. Its head is large and round with a prominent yellow eye and a short, stout beak.
