Jerdon's courser
The Jerdon's courser (''Rhinoptilus bitorquatus'') is a nocturnal bird belonging to the pratincole and courser family Glareolidae endemic to India. The bird was discovered by the surgeon-naturalist Thomas C. Jerdon in 1848 but not seen again until its rediscovery in 1986. This courser is a restricted-range endemic found locally in India in the Eastern Ghats of Andhra Pradesh. It is currently known only from the Sri Lankamalleswara Wildlife Sanctuary, where it inhabits sparse scrub forest with patches of bare ground.
== Description ==
It is an unmistakable compact courser, with two brown breast-bands. It has a yellow base to the black bill, a blackish crown, broad buff supercilium, and orange-chestnut throat patch. A narrow white crown stripe runs on top of the head. In flight it shows a mostly black tail and a prominent white wingbar. It is crepuscular and vocal at dawn and dusk with a series of staccato ''Twick-too...Twick-too... Twick-too'' or ''yak-wak.. yak-wak'' calls. The notes are repeated at the rate of about 1 per second and uttered 2 to 16 times and several birds in the vicinity may join in the calling.
Jerdon described the Telugu name of the species as ''Adavi wuta-titti'' meaning "Jungle empty-purse". This name may however have been in error since Salim Ali and Hugh Whistler found villagers mystified by the name when they searched for the species near Borgampad and Nelipaka during the Hyderabad state survey of 1931. Recent researchers have noted the local name as ''Kalivi kodi''.
