Grassland, cropped fields, and scrubs in the Indus valley of central Bangladesh, India, Nepal and Pakistan, ranging across the Gangetic plains, and parts of peninsular continental India. Mostly seen in winter further south.The male has a black breast-patch and distinctive head pattern of black and white. the male has a very noticeable stripe on the crown and supercilium with a black and white pattern on the head and neck, a black ‘anchor’ mark on the throat and a prominent black patch on the breast. A black border highlights the white neck. The flanks are streaked with black. The female is difficult to separate from female common quail and Japanese quail, although the spots on the breast are more delicate. The call is a metallic chrink-chrink, constantly repeated mornings and evenings, and in the breeding season also during the night.
The rain quail has a very large range and the population is stable. It is a common species and the International Union for Conservation of Nature has rated their conservation status as “least concern”.
