Résumé :	The forests of the Angolan highlands are the smallest and most isolated of the Afromontane centres of endemism. Despite their high biodiversity value and small, fragmented extent of less than 200 ha, they remain entirely unprotected. Here we draw attention to their uniqueness and the threats to their conservation. We specifically highlight the importance of Mt Moco to bird conservation and describe current forest cover and condition. Sixty-four endemic/near-endemic species/subspecies and taxa with isolated populations are associated with the highlands of western Angola. All 19 forest-dependent taxa are among the 233 species recorded at Mt Moco, which include a rich diversity of montane specialists. Swierstra's Francolin Pternistis swierstrai is the only threatened endemic. In 2009, 10 of 30 forest patches at Mt Moco larger than 0.5 ha were surveyed for this species. It occurred in seven of these surveyed patches, at a mean minimum density of 0.95 pair ha(-1) in forest patches > 1 ha. Based on extrapolations of this figure, we estimate a minimum of
