Along with condors, swans and turkeys, the kori bustard (Ardeotis kori) is one of the world’s heaviest flying birds, as well as being the largest of all bustards. Imposing in stature, it has a bulky body, a long, thick neck, and long, yellow legs. The face and neck are predominately grey, but a distinctive black crest runs back from the crown. Aside from a black patch at the base of the neck, and black and white speckling around the shoulders, the upperparts are mostly brown, whilst the underparts are white. Although the female has a very similar plumage to the male, it is conspicuously smaller in size.
