Distribution
Southern Angola and northeastern Namibia, Botswana, southwestern Zambia and Zimbabwe, southern Mozambique, northern South Africa and Swaziland
Taxonomy
This is a monotypic species[2].
Formerly lumped with Buff-crested Bustard and Savile's Bustard.7
Lophotis vs. Eupodotis
The species in genus Lophotis was formerly placed in genus Eupodotis by some authorities, however there now seems to be a consensus for using Lophotis.
Habitat
Semi-arid woodlands, extending into sparsely wooded grassland in the southern Kalahari.
Behaviour
Solitary; inconspicuous unless calling or displaying.
Diet
Forages for invertebrates such as beetles, grasshoppers, ants and termites; also berries, seeds, fruits and gum while walking.
Breeding
Polygynous. The mating display of the male is spectacular; he flies up vertically to a height of 10-30 m, throws his feet up, tumbling over and drops to the ground like a stone, opening his wings at the last minute.
Females are probably not territorial, but nest alone. The nest is a shallow scrape in the ground, often near a shrub or sapling. One to two eggs are laid October to April, peaking earlier in the east. Only the females incubate and care for the young.
Vocalisation
When displaying, the male has an extended vocalisation which starts with a long, accelerating series of clicks: tic, tic, tic, finishing with a long series of piping whistles: pi pi pi pipity pipity. It can also make a squeaky, whistling sound that is very ventriloquial.
