The Namaqua dove is a tiny sparrow-sized pigeon, typically 22 cm in length with a 28–33 cm wingspan, and weighing 40g. It has a very long black tapered tail, and the size and shape have led to comparison with the budgerigar. The plumage is mostly grey apart from a white belly, and chestnut primary feathers which are visible in flight.
The adult male has a yellow and red beak and a black face, throat and breast. The adult female lacks the black and has a red-based grey bill. Young birds are dark blotched on the wings and shoulders, and otherwise resemble the females.
The song is a quiet, short, double hoo, higher on the longer second note kuh-whooo, mournful and frequently repeated.
