Similar species

Very similar to Australian Bustard, but ranges don't overlap.

Distribution

Patchily found in northwestern and central India.
A critically endangered species. Extinct in Pakistan and has been extirpated from more than 90% of its former range. Now confined to small patches of grassland, mostly in nature reserves. Population estimated at less than 300 birds, mainly in Rajasthan. Threatened by rapid habitat loss and hunting.

Taxonomy

This is a monotypic species.
Forms a superspecies with Australian Bustard and has been considered conspecific with the latter and Kori Bustard.

Behaviour

Like Kori Bustard this species sits down to drink, unlike other bustards.

Diet

An opportunistic feeder. Takes grain, shoots, berries, locusts, grasshoppers, beetles, centipedes, lizards, small snakes and mammals.
Forms small feeding flocks in winter, sometimes associating with antelopes.

Breeding

Breeding throughout the year, varying with area and rainfall. Displaying male inflates white-feathered gular pouch, folds tail over back and struts about with drooped wings and head held high, calling periodically.
The nest is a shallow scrape, often with no cover. Lays 1 egg, sometimes 2.
