Cape Rock Thrush
Monticola rupestris
This bird is large and stocky for a rock thrush, measuring 21-22 cm (8.26in) in length. The adult male during the summer features a blue-grey head, orange underparts and outer tail feathers, and brown wings and back. Females have a brown head and richer orange underparts compared to other female rock thrushes. Vocalizations are an important aspect of this species’ behavior. The male produces a whistled song described as “tsee-tsee-tseet-chee-chweeeoo” and is known to mimic other bird species.
