Spatial distribution of the community of birds of the Koko urban dam and its surroundings (Korhogo, Côte d’Ivoire)

The spatial distribution of the bird community of the Koko urban dam and its surroundings (Korhogo; Côte d’Ivoire), was studied for the first time from February 2016 to January 2017. The inventory method consisted of a slow walk, punctuated by a 15-minute stop, along the banks of the dam in order to test the effect of habitats on the distribution of the bird community. A total of 1,613 birds, divided into 63 species belonging to 32 families and grouped into 14 orders, were inventoried. The Passeriformes order and the Ardeidae family were the best represented. Diversity was highest in the wooded savannah and the prairie. Migratory species were most numerous in the water while resident species were best represented in the prairie and wooded savannah. The distribution of bird species has shown that prairie and tree savannah have been the preferred habitats of this community. Therefore, these refuge habitats must be preserved in light of the anthropogenic pressures experienced by this ecosystem, which could pose a threat to this community.

科特迪瓦科霍戈市的科科城市水坝及其周边区域的鸟类群落空间分布，于2016年2月至2017年1月首次开展研究。本研究采用沿水坝岸线缓步行进、每行进一段距离后停留15分钟的调查方法，以探究生境对鸟类群落分布的影响。本次调查共记录到鸟类1613只，隶属于14目、32科、63种，其中雀形目（Passeriformes）与鹭科（Ardeidae）为类群丰度最高的类群。树木稀树草原与草原生境的鸟类多样性最高；迁徙鸟类在水域生境中数量最多，而留鸟则在草原与树木稀树草原生境中占比最高。鸟类物种的分布特征表明，草原与树木稀树草原是该鸟类群落的首选栖息生境。鉴于该生态系统正面临人为活动带来的压力，这些庇护生境亟需得到保护，否则将对该鸟类群落构成生存威胁。
