The results of synchronous mid-winter waterbird census of the Azov-Black Sea region (Ukraine) in 2015

This dataset is part of the data obtained during the synchronous mid-winter waterbird census of the Azov-Black Sea region of Ukraine. It includes 284 records of 54 species of waterfowl during 12-29 January 2015. The Azov-Black Sea region is located in the steppe zone in the south of Ukraine. It is of great importance for migratory birds, especially waterfowl, as the combination of natural complexes creates good conditions for birds to rest and feed. In addition, The Azov-Black Sea region is on the border of the wintering areas of many wetland bird species, especially Anseridae and waders. The warming of the climate is well reflected over the years in the advancement of the limit of possible wintering in the northeastern direction, which is clearly visible in the change in the species composition and number of wintering wetland birds in the region. The length of the region is about 800 km. There are 23 Ramsar wetlands with a total area of 767,396.3 hectares within its boundaries.

本数据集源自乌克兰阿佐夫-黑海地区同步冬季水鸟调查所获取的数据。该数据集记录了2015年1月12日至29日期间，54种水禽的284条记录。阿佐夫-黑海地区位于乌克兰南部草原地带，对于候鸟，尤其是水禽而言，其自然复合体的结合为鸟类提供了良好的休息和觅食条件。此外，该地区位于众多湿地鸟类物种越冬区的边界，尤其是鸭科和涉禽。气候变暖的趋势在历年中通过可能越冬范围的东北方向推进得到了充分体现，这在区域越冬湿地鸟类物种组成和数量的变化中表现得尤为明显。该地区的长度约为800公里，其边界内共有23个拉姆萨尔湿地，总面积达767,396.3公顷。
