分布与栖息地
This species is found mainly in the dry scrub regions and agricultural lands and is often found close to water. The largest populations are in central and north-western India. A population of escaped birds once existed near Lahore. The key areas where they are well known are in central India, around southern Rajasthan specifically around Oriya village, central Uttar Pradesh, southern Bihar and West Bengal extending south to southern Maharashtra and northern Andhra Pradesh. Some records are from further south from Wynaad in northern Kerala but it is unclear if these are wild populations.

行为
They breed in central India from October to January but are also known to breed in July. The nest is made out of broad leaves of grass or sugarcane and is spherical with an entrance on the side. The adaptability for altered habitats is a positive side of its natural survival. Several nests may be built in the vicinity by pairs that form a loose colony. They forage in small groups especially in the non-breeding season. The clutch is four to six eggs.<p>Its voice song is high-pitched warble, ending with prolonged trill with weak seee and swee notes not unlike that of Turdoides subrufus.

Typically seen in pairs moving through the lower and middle levels; not particularly skulky.
Little Tinamou
Crypturellus soui
Furtive, almost tailless small game bird that lives on the ground in humid tropical lowlands. Favors forest edge and dense secondary growth rather than forest interior. When disturbed runs rather than flies. Very rarely seen (sometimes crosses quiet roads or trails), but tremulous whistles are often heard, especially early and late in the day. Plumage is dark brownish overall with grayer head and whitish throat.
