The chestnut-bellied sandgrouse or common sandgrouse (Pterocles exustus) is a species of sandgrouse. It is a sedentary and nomadic species that ranges from northern and central Africa and further east towards western and southern Asia. There are six recognised subspecies.
The chestnut-bellied sandgrouse is sexually dimorphic in plumage colouration and varies in overall plumage colouration between the six subspecies.
The chestnut-bellied sandgrouse is a bird of barren, semi-deserts. It is heavily reliant on water, despite living in hot, arid climates and is known to travel up to 80 kilometres in a day to search for water.
Chestnut-bellied sandgrouse are selective feeders which primarily subsist on seeds, often preferring to consume small seeds in large amounts.
The chestnut-bellied sandgrouse is sedentary, unlike most species of sandgrouse who are migratory. However, the species exhibits extensive local movements. During the summer, when water is scarce, the birds will move to nearby areas where water is still available. The birds also appear to periodically move over long distances based on the availability of food supplies.
