Summary The southern Langeberg is defined as the Langeberg Range between Kogmanskloof and the Gourits River. The Langeberg is one of several east–west trending mountain ranges in the Western Cape. In the fynbos, the Orange-breasted Sunbird Anthobaphes violacea is widespread in ericas, while the Cape Sugarbird Promerops cafer and Protea Seedeater Crithagra leucoptera also occur here.
