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.

Coiban Mastuff Bat

The Coiban Mastuff Bat (Molossus coibensis) is a small free-tailed bat in the family Molossidae, named for Coiba Island off the Pacific coast of Panama, where specimens were first collected. Members of the genus Molossus are robust, fast-flying insectivores adapted to open-air foraging above the forest canopy and over water, characterised by narrow wings and a tail that extends beyond the patagium (wing membrane). Molossus coibensis inhabits lowland tropical forests and adjacent open habitats in Central America and northwestern South America, with confirmed records from Colombia, Ecuador, Venezuela, and Panama, indicating a distributional range that extends well beyond its type locality on Coiba Island. Like other mastiff bats, it roosts in crevices within buildings, rock faces, and hollow trees, emerging at dusk to pursue aerial insects at speed. The species feeds primarily on large beetles, moths, and other night-flying insects, typically hunted high above the forest. It is assessed as Least Concern by the IUCN based on its relatively wide range and tolerance of modified habitats. Molossus coibensis was long treated as a subspecies of Molossus molossus before being recognised as a distinct species based on morphological and molecular evidence. Ecological and life-history data specific to this taxon remain limited.
