Road Edge; Nest Survival; Nest Predation; Nest Predators

Edge effects cause changes in bird community richness, abundance, and/or distribution within a landscape, but the avian guilds most infuenced can vary among regions. Although Southeast Asia has the highest rates of deforestation and projected species loss, and is currently undergoing an explosive growth in road infrastructure, there have been few studies of the efects of forest edges on avian communities in this region. We examined avian community structure in a dry evergreen forest in northeastern Thailand adjacent to a five-lane highway. The surveys were conducted during February-August 2014 and March-August 2015. We found a strongly negative response to the forest edge for bark-gleaning, sallying, terrestrial, and understory insectivores and a weakly negative response for arboreal frugivore-insectivores, foliage gleaning insectivores, and raptors. Planners should avoid road development in forests of high conservation value to reduce impacts on biodiversity.
