Food: Seeds, leaves, flowers, wheat grains, insects, lizards,and frogs.


 

Status: Rare species. According to the IUCN Red List categories and criteria,the species evaluated as – Vulnerable.


Distribution and Range: Once widely distributed on Mongolian steppes, the species were sighted in small numbers in open spaces of the Dornod, Khentii, Sukhbaatar, Tov, Khangai, Bulgan, Selenge, Zavkhan and Uvs Aimags. Used to winter in Jargalant of Tov Aimag and occasionally near the Lag Lake in Dornod Aimag. In recent years, the species winter on agricultural fields of the Eg, Tarbagatai, Tarialan, Erdene, Bulgan soums in small groups from 20-to 100 individuals.


Habitat: Mongolian open steppes, river valleys, meadows, forest edge steppe and wheat fields in winter.


Population and Threats: Population not assessed. Threats: habitat degradation due to livestock grazing in the breeding sites, cutting grass, cultivating, loss of food supply due to chemicals, fire hazards, dzud and poaching, close to persishing due to natural and anthropogenic factors. Chicks are preyed upon birds of prey, foxes, wild fox, wolves, dogs. Desease transmitted by parasites.
