The eggs are at risk of destruction from other animals particularly ungulates and crows. Females may use a distraction display that involves flying zigzag with dangling legs. Status In 2011 Birdlife International uplisted this species from Endangered to Critically Endangered, mainly because it has been extirpated 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 Rajasthan, Karnataka, Maharashtra, Madhya 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. Other sanctuaries with the species include Kutch Bustard Sanctuary of Naliya in Kutch, Karera Wildlife Sanctuary in Shivpuri district;Great Indian Bustard Sanctuary near Nannaj, 18 km from Solapur in Maharashtra, Shrigonda 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. A 2011 study of the variability in mitochondrial DNA (hypervariable control region II and cytochrome b) in 63 samples from 5 Indian states found very low genetic diversity suggesting a historical population reduction. The study suggested a population reduction or near extinction estimated about 20–40,000 years ago. Attempts to breed them in captivity in the 1970s failed. The species is considered as "critically endangered" by the IUCN Red data list. Conservation The rapid reduction of the population of India's bustards, their endangered status and the decline of grasslands led the Ministry of Environment and Forests to prepare species recovery programs in 2012 for three species of bustard; the great Indian
