Chorister Robin-Chat

The Chorister Robin-Chat (Cossypha dichroa) is a medium-sized, colourful thrush-like bird in the family Muscicapidae, endemic to the forests of South Africa and Eswatini, particularly the humid montane and coastal forests of KwaZulu-Natal, the Eastern Cape, and the escarpment forests of Mpumalanga and Limpopo. Robin-chats of the genus Cossypha are renowned across sub-Saharan Africa for their beautiful, complex songs, and the Chorister Robin-Chat lives up to the group's musical reputation — it is widely regarded as one of the finest songsters among southern African forest birds, producing rich, melodious phrases of extraordinary variety from within dense forest undergrowth. The species is characterised by striking orange and black plumage with a white supercilium (eyebrow stripe), and despite its colourful appearance remains surprisingly difficult to see in dense forest shade. It forages in low vegetation and on the forest floor for insects, worms, and small invertebrates. Like other Cossypha, it is territorial and sings year-round. The IUCN classifies it as Least Concern, with populations stable across its range of Afromontane and coastal forests. Threats include habitat loss from forestry, urban expansion, and alien plant invasion, though the species persists in many forest patches.
