The rain quail or black-breasted quail (Coturnix coromandelica) is a species of quail found in the Indian subcontinent, its range including Pakistan, India, Nepal, Sri Lanka, Bangladesh, Myanmar, Thailand, Cambodia and Viet Nam.
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 rain quail lacks barring on primaries. The male has a black breast-patch and distinctive head pattern of black and white. The female is difficult to separate from female common quail and Japanese quail, although the spots on the breast are more delicate. It is 6–6.5 in (15–17 cm) and weighs roughly 2.25–2.5 oz (64–71 g).
The call is a metallic chrink-chrink, constantly repeated mornings and evenings, and in the breeding season also during the night. It is quite unmistakably distinct from the call of the common grey quail.
The rain quail feeds on seeds of grasses and other plants, insect larvae and small invertebrates. Breeding takes place between March and October, but chiefly after the start of the southwesterly monsoon season in June. The eggs are laid in a scrape in the ground, sometimes in the open under a Euphorbia or similar bush. There are usually six to eight eggs in the clutch. The incubation period is sixteen to eighteen days. The chicks are able to leave the nest soon after they have hatched and remain with their parents for about eight months.
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".
