咖啡是最重要的热带商品，在生物保护高度优先的地区种植。国际上有大量关于咖啡农场保护价值的文献，但在非洲对此主题的研究很少。埃塞俄比亚是一个多元化且研究较少的国家，鸟类特有程度高，保护挑战紧迫，也是阿拉比卡咖啡的起源地。我们在三年内利用标准薄雾网程序在埃塞俄比亚的七个地点对遮荫咖啡农场和潮湿的常绿非洲山森林中的鸟类群落进行了采样，以评估鸟类物种的丰富度、多样性和群落结构。尽管遮荫咖啡和森林之间的物种多样性没有差异，但遮荫咖啡农场的物种丰富度是森林地点的两倍以上，并且九种古北区迁徙物种中除一种外，所有物种均仅在遮荫咖啡中捕获。森林中的森林专家和林下食虫动物相对丰富，这表明少受干扰的森林对于维持这些高危鸟类群体至关重要。尽管如此，在主要森林控制点记录的所有物种也记录在遮荫咖啡中，这表明埃塞俄比亚遮荫咖啡可能是世界上最“鸟类友好”的咖啡。对于保护非洲森林鸟类的努力以及可能受益于鸟类害虫监管和生物多样性友好型咖啡认证的遮荫咖啡种植者来说，这是一个重要发现。 (C) 2015 Elsevier Ltd. 保留所有权利。
Coffee is the most important tropical commodity and is grown in high-priority areas for biological conservation. There is abundant literature on the conservation value of coffee farms internationally, but there has been little research on this topic in Africa. Ethiopia is a diverse and little-studied country with high levels of avian endemism, pressing conservation challenges, and where Coffee arabica originated. We sampled bird communities in shade coffee farms and moist evergreen Afromontane forest in Ethiopia utilizing standard mist netting procedures at seven sites over three years to evaluate bird species richness, diversity and community structure. Although species diversity did not differ between shade coffee and forest, shade coffee farms had over double the species richness of forest sites and all but one of the nine Palearctic migratory species were captured only in shade coffee. There was a greater relative abundance of forest specialists and understory insectivores in forest, demonstrating that little-disturbed forest is critical for sustaining these at-risk groups of birds. Nonetheless, all species recorded in primary forest control sites were also recorded in shade coffee, indicating that Ethiopian shade coffee is perhaps the most "bird-friendly" coffee in the world. This is an important finding for efforts to conserve forest birds in Africa, and for shade coffee farmers that may benefit from avian pest regulation and biodiversity-friendly coffee certifications.
