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.

Comportamento

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.
