MacQueen's bustard is found in the desert and steppe regions of Asia, east from the Sinai Peninsula extending across Kazakhstan east to Mongolia. The species feeds throughout the day, but is most active at dawn and dusk. It has a diverse diet, mainly comprising plants and invertebrates, but also including vertebrates such as rodents, lizards, small snakes and even young birds. Males attract their mates with an extravagant courtship display which they perform at the same site each year.
