摘要

尼罗河三角洲进入阿尔伯特湖,是拉姆萨尔湿地的一部分,支持35平方公里的纸莎草沼泽,流经河道。在2017-2018年的12个月里,我们每月在沼泽边缘的20个点进行鸟类计数,每次10分钟。总的来说,记录了143种,其中13种在纸莎草纸上特别常见,在河道沿线也有类似的数量。在观察到的七种纸莎草限制物种中,有三种是全球红色名录,特别是纸莎草gonolek和shoebill。大多数物种是常住的,但白翅燕鸥和一些水鸟物种是季节性的。我们应该在未来几年重复我们的基线计数,同时记录潜在的威胁——气候变化、石油和天然气作业以及其他人类活动。拉姆萨尔的大部分(但不是全部)都在默奇森瀑布国家公园(Murchison Falls National Park)内,该公园受到了很好的保护;如有可能,应将保护范围扩大到整个场地。

Birds of an Extensive Papyrus Swamp in Uganda and Their Conservation
ABSTRACT The delta of the Nile as it enters Lake Albert is part of a Ramsar site and supports 35 km2 of papyrus swamp through which run channels of the river. For 12 months in 2017-2018, we made monthly bird counts, each of ten minutes, at 20 points along swamp edges. Overall, 143 species were recorded, of which 13 were particularly common in the papyrus, and a similar number along the channels. Of seven papyrus-restricted species observed, three are globally red-listed notably papyrus gonolek and shoebill. Most species are resident, but white-winged terns and several hirundine species were seasonally common. Our baseline counts should be repeated in future years as well as recording potential threats—climate change, oil and gas operations and other human activities. Most, but not all, of the Ramsar site is within Murchison Falls National Park, which is well-protected; if possible, the protection should be extended to the whole site.
