The study describes a pilot survey on bats in the highest areas of Pirin Mountain. The methods included examining subfossil bone remains, mist-netting, and recording echolocation calls. The study was conducted in August 2002 and 2013 and from 2019 to 2020. While in general, bat diversity tends to decrease with increasing altitude due to harsher environmental conditions, the present study, despite a short period, reveals high diversity. Twenty species, more than half of the Bulgarian bat fauna, were detected. The recording and analysis of vocal signatures proved to be the best way to inventory bat diversity. At least 13 species were detected by this method. and together make up more than 60% of all reliably determined echolocation sequences. Significant activity was found for , , , and . The registration of the latter species is of considerable faunistic interest. It was previously only known from a single specimen at one location in the country. The sex and age structure of the bat assemblage suggests that it is likely a swarming assemblage. The area is the highest swarming location in Europe. The results provide valuable information on bat ecology and behaviour, which can be used to inform management and protection efforts.
该研究描述了一项关于皮林山最高区域蝙蝠的试点调查。方法包括检查亚化石骨骼残骸、使用雾网捕捉以及记录回声定位叫声。该研究于2002年8月、2013年以及2019年至2020年期间进行。一般来说，由于环境条件更为恶劣，蝙蝠多样性往往会随着海拔升高而降低，但本研究尽管时间较短，却揭示出了较高的多样性。共检测到20种蝙蝠，超过了保加利亚蝙蝠动物群的一半。事实证明，记录和分析声音特征是清查蝙蝠多样性的最佳方法。通过这种方法至少检测到了13种蝙蝠。[此处原文缺失两种蝙蝠的名称]和[此处原文缺失两种蝙蝠的名称]共同构成了所有可靠确定的回声定位序列的60%以上。发现[此处原文缺失四种蝙蝠的名称]有显著活动。后一种蝙蝠的记录具有相当大的动物区系研究价值。它此前仅在该国一个地点的单个标本中被发现过。蝙蝠群落的性别和年龄结构表明，这可能是一个群居群落。该区域是欧洲最高的群居地点。研究结果为蝙蝠生态和行为提供了有价值的信息，可用于指导管理和保护工作。
