The Karoo prinia, or spotted prinia (Prinia maculosa), presents itself as a small, active passerine bird, measuring between 13 to 15 centimeters in length. It is adorned with short, rounded wings, a longish tail that it often holds cocked, and robust legs. Its bill is short and straight, colored a deep black. The bird's head features a whitish eyebrow, while the upperparts are a plain brown. The throat and lower face are whitish with dark streaking, and the underparts are a pale yellowish white or yellow, marked with distinct black streaking. A notable dark spot near the end of the long tail adds to its distinctive appearance. The feet and legs are a pinkish-brown, and the eye is a deep, dark brown. Both sexes of the Karoo prinia are identical in plumage, though juveniles can be distinguished by their much yellower underparts and lighter streaking.
When identifying the Karoo prinia, look for the bird's whitish eyebrow and the streaked underparts. The tail is typically held at an angle and has a dark spot near the end. Juveniles are yellower below and less heavily streaked than adults.
