The little bustard is a smaller bird, the male being slightly larger than the female. The male bustard measures 43 cm in length and weighs 800 to 975 grams. The female bird measures 43 cm and weighs 680 to 950 grams. The breeding male is brown above and white below. Head is grey with a black neck bordered above and below by white. The non breeding male and female lack the neck border. The female little bustard is darker than the male.

Habitat

These bustard species inhabit open grasslands and undisturbed cultivation, with plants and grass tall enough for cover.

Feeding habits

These bustard species are omnivorous, feeding on seeds, shoots, berries, insects, small rodents and reptiles.

Breeding

The male bustard makes breeding displays with foot stomping and leaping in the air. Females lay 3 to 5 eggs in the nest on the ground. The female does the incubation of eggs and rearing of the chicks.

Distribution

The little bustard is distributed in Russia, Georgia, Kyrgyzstan, Kazakhstan, Azerbaijan, Ukraine, north-west China, Iran, Spain, Turkey, Portugal, Italy and France. Wintering birds occasionally move up to Indian Subcontinent.

Movement Patterns

The little bustard populations in Southernmost Europe are mainly resident. Other populations in Europe and Asia migrate further south in winter.

Status and conservation

The global population of these bustard species has been estimated at a minimum of 260,000 individual birds. The decline in grasslands and low-intensity cultivation has directly contributed to sharp decline in the population. The habitat loss and poaching are the major threats in conserving these species.

The IUCN (International Union for Conservation of Nature) has categorized and evaluated these bustard species and has listed them as "Near Threatened".
