Great Indian bustard

The Great Indian Bustard (Ardeotis nigriceps) or Indian bustard is a bustard found in India and the adjoining regions of Pakistan. A large bird with a horizontal body and long bare legs, giving it an ostrich like appearance, this bird is among the heaviest of the flying birds. Once common on the dry plains of the Indian subcontinent, as few as 250 individuals were estimated in 2011 to survive and the species is critically endangered by hunting and loss of its habitat, which consists of large expanses of dry grassland and scrub. These birds are often found associated in the same habitat as blackbuck.

In 2011 Birdlife International uplisted this species from Endangered to Critically Endangered, mainly because it has been exirpated from 90% of its former range and the population was estimated at perhaps fewer than 250 individuals in 2008. The main threats are hunting and habitat loss. In the past they were heavily hunted for their meat and for sport and, today, poaching of the species may continue. In some places, such as Rajasthan, increased irrigation by the Indira Gandhi canal has led to increased agriculture and the altered habitat has led to the disappearance of the species from these regions. Some populations migrate into Pakistan where hunting pressure is high.The bird is found in RajasthanKarnatakaMaharashtraMadhya Pradesh and Gujarat states of India. Desert National Park, near Jaisalmer and coastal grasslands of the Abdasa and Mandvi talukas of Kutch District of Gujarat support some populations.Ghatigaon and Karera sanctuaries in Madhya Pradesh once held sizeable populations.[23] Other sanctuaries with the species include Naliya in Kutch,Karera Wildlife Sanctuary in Shivpuri district;Great Indian Bustard Sanctuary near Nannaj,18 km from Solapur in MaharashtraShrigonda taluka in Ahmednagar district of Maharashtra, near Nagpur and near Warora in Chandrapur district in Maharashtra and Rollapadu Wildlife Sanctuary, 45 km from Kurnool in Andhra Pradesh.At Ranibennur Blackbuck Sanctuary, habitat changes have affected the populations of blackbuck and bustards. In the 1950s the scrub forest was replaced with Eucalyptus plantations. These helped wildlife when the trees were short but after their extensive growth they made the adjoining grassland less favourable for bustards.
