Which species of bird in the Otididae family is shown in the picture?

The blue korhaan or blue bustard (Eupodotis caerulescens) is a species of bird in the Otididae family which is native to South Africa. It's known to make a call that is a series of frog-like croaks, usually uttered in flight. Its natural habitat is plateau grassland, dry shrubland, arable land, and pastureland. The blue korhaan preferred habitat is one with short grassland and flat topography.

This is a bird known as a robust, ground-dwelling bird with a striking appearance. It has a sturdy body, a large head, a long neck, and long legs with short toes. The adult bird's length ranges from 50 to 58 centimeters. Males are distinguished by their black foreheads and crowns, with white on the sides of the head. Their backs, wings, and tails are brown, while the neck, throat, breast, and belly exhibit a bluish-grey hue. Females are similarly colored but have a duller grey on the neck and underparts, and buff ear coverts. Both sexes sport yellow legs and feet.

When noting the behavior of the blue korhaan, it is seen as a largely terrestrial bird. When disturbed, it may crouch down or walk or run away with its head dipped. If it is further alarmed, it will take flight, covering considerable distances. The birds are often seen in pairs or in small family groups. As of 2017, the International Union for Conservation of Nature (IUCN) estimated the population of blue korhaans to be between 8,000 and 10,000 mature individuals. It is currently classified as "Near Threatened".
