About Eupodotis caerulescens (Vieillot, 1820)
Eupodotis caerulescens, commonly known as the blue korhaan, is a species of ground-dwelling korhaan bird. All korhaans are ground-dwelling birds with sturdy bodies, large heads, long necks, long legs and short toes. The blue korhaan is a fairly large bird, reaching a total length of 50 to 58 cm (20 to 23 in). For this species, the forehead and crown are black, while the sides of the head are white. Males have brown backs, wings and tails, and bluish-grey necks, throats, breasts and bellies. Females have similar overall colouring, but their necks and underparts are a duller grey, and their ear coverts are buff. The blue korhaan's legs and feet are yellow. Its call is a series of throaty "krok-kau" notes, most often heard around dawn, and regularly uttered while in flight. The blue korhaan is native to South Africa and the western fringes of Lesotho. Its range extends southward from Pretoria and Mbombela to Bhisho, covering an area of approximately 356,000 km² (137,000 mi²). It inhabits grassland at altitudes between 1,500 and 3,000 m (5,000 and 10,000 ft). It favours short grass habitats with scattered karoo-type dwarf shrubs, termite mounds and few trees, and it typically occurs within one kilometre of a water source. It can also be found in previously cultivated land, fallow areas, winter crop fields, and pasture. The blue korhaan is largely terrestrial. When disturbed, it crouches down, and when approached closer it tends to walk or run away with its head lowered. If strongly alarmed it will flush into the air and fly a considerable distance. It usually occurs in pairs or small family groups, and forages for insects, lizards, scorpions, seeds, flowers and leaves. Breeding mainly occurs in October and November. The nest is a shallow scoop dug into the ground, often placed in thick foliage, where one to three eggs are laid. Incubation lasts approximately 26 days, and family groups may stay together for up to two years.
