This dataset is the first effort to combine the audio biodiversity of a taxonomic group in a selected location, the Boyacá department in Colombia. We conducted a detailed review of the sound recordings for birds from the Boyacá department within three repositories, the environmental sound collection of the Humboldt Institute, the Macaulay Library of the Cornell Lab of Ornithology, and the xeno-canto platform of the Naturalis Biodiversity Center. We selected recordings that were identified up to species and had complete metadata information. Using latitude and longitude information, we assigned each recording to one of the three regions and one of the 12 biotic units reported for Boyacá. We reported a total of 2321 recordings belonging to the Andean region (1892), Orinoquian region (425), and Carare-Lebrija-Nechi-Sinu (4). The sounds of Boyacá birds have been sampled for approximately three decades, with two peaks of activity in the early 2000's and 2018. We also included a map with the distribution of biotic units and sound recordings of our dataset. This dataset can be used to extract acoustic traits to test hypotheses of turnover in the acoustic space or traits by species, or to compare acoustic traits between species. It can also allow decision-makers to support biodiversity-based economies such as avitourism.
该数据集是首次尝试整合选定地点（哥伦比亚博亚卡省）某一分类群的音频生物多样性。我们对来自博亚卡省的鸟类录音进行了详细审查，这些录音存于三个资料库中，分别是洪堡研究所的环境声音集、康奈尔鸟类学实验室的麦考利图书馆以及荷兰国家自然生物多样性中心的xeno-canto平台。我们挑选了已鉴定到物种且具有完整元数据信息的录音。利用经纬度信息，我们将每条录音分配到三个区域之一以及博亚卡省报告的12个生物单元之一。我们共报告了2321条录音，分别属于安第斯地区（1892条）、奥里诺科地区（425条）以及卡拉雷 - 莱布里亚 - 内奇 - 锡努地区（4条）。博亚卡省鸟类的声音采样大约持续了三十年，在21世纪初和2018年出现了两个活动高峰。我们还纳入了一张地图，展示了生物单元的分布以及我们数据集的声音录音。该数据集可用于提取声学特征，以检验声学空间或物种特征的周转率假设，或比较物种之间的声学特征。它还能让决策者支持基于生物多样性的经济活动，如观鸟旅游业。
