Threatened birds of the Angolan Central Escarpment: distribution and response to habitat change at Kumbira Forest

  • Aimy Cáceres (a1), Martim Melo (a1), Jos Barlow (a2), Paulo Cardoso (a3), Francisco Maiato (a4) and Michael S. L. Mills (a5)...

Kumbira Forest is the best representative area of Angola's Central Escarpment and the only site known to hold significant populations of four of the five threatened endemic bird species of this habitat. However, the forest is disappearing as a result of human activities. Remote-sensing techniques were used to assess changes in forest cover, and bird and habitat surveys were performed to assess the effect of land-use changes on endemic species and the bird community. No relationships could be established between the presence of endemics and habitat and landscape variables. This lack of effect may be attributable to the low number of records and compounded by the mosaic structure of the landscape. Although forest cover has been maintained in Kumbira, old-growth forest has been replaced by secondary growth in many areas. Nevertheless these secondary-growth forest patches can maintain a bird community similar to that found in old-growth forest.
