This lark is a 15-cm-long bird, with a brown crown, rich rufous underparts, and a strong bill. It has brown upperparts (greyer in the north of its range). Its call is an ascending "pooooeeeee ".
The eastern clapper lark is found in much of the drier parts of southern Africa in Zambia, Namibia, Botswana, Lesotho and South Africa. It is a species of open grassland and savannah.
The eastern clapper lark is a skulking species, difficult to find when not displaying. It is not gregarious, and individuals tend to be seen in dry habitats feeding on the ground on seeds and insects. The display commences with an ascending flight with wing flapping. It then parachutes down with trailing legs.
