The Colombian Tropical Andes are one of the regions with highest bird diversity on Earth. However, information on bird morphology, reproductive phenology, and molt is particularly scarce in this region. Also, this region is heavily impacted by deforestation, and it is vulnerable to climate change. Hence, providing baseline information on life history and morphological traits will be essential to support future research on functional diversity, climate change effects, conservation, evolution, and phenology. To fill this gap, we have compiled information on bird distribution, morphology, molt, and reproductive phenology at 52 localities of the Department of Caldas, covering an elevation range between 148 and 3845 m. This compilation comprises a wide range of habitats, including native forests, forestry plantations, croplands, and paramo. Our database presents information for 3398 records belonging to 379 bird species (representing 23 orders, 53 families, and 258 genera). From those records, 2843 correspond to information collected in the field between 2008 and 2019, and the remaining 555 records correspond to specimens deposited in the Natural History Museum of the Caldas University, collected between 1969 and 2014. We measured nine morphological traits from all specimens: total culmen, gape, bill width, bill depth, tarsus, wing length, tail length, total length, and weight. We also have reproductive condition information for 257 species and molt information available for 378 species. The information contained in this dataset represents ~20% of the Colombian avifauna and ~11% of the bird species richness in South America. This data set is released for non-commercial use only.

哥伦比亚热带安第斯山脉 379 种鸟类的形态、繁殖和蜕皮物候数据库

哥伦比亚热带安第斯山脉是地球上鸟类多样性最高的地区之一。然而，该地区关于鸟类形态、生殖物候和蜕皮的信息特别稀少。此外，该地区受到森林砍伐的严重影响，容易受到气候变化的影响。因此，提供关于生活史和形态特征的基线信息对于支持未来对功能多样性、气候变化影响、保护、进化和物候学的研究至关重要。为了填补这一空白，我们收集了卡尔达斯省 52 个地点的鸟类分布、形态、蜕皮和繁殖物候信息，覆盖海拔范围在 148 米和 3845 米之间。该汇编包括广泛的栖息地，包括原始森林、林业种植园、农田和帕拉莫。我们的数据库提供了属于 379 种鸟类（代表 23 个目、53 个科和 258 个属）的 3398 条记录的信息。从这些记录中，2843 条对应于 2008 年至 2019 年期间在该领域收集的信息，其余 555 条记录对应于存放在卡尔达斯大学自然历史博物馆的标本，这些标本是在 1969 年至 2014 年间收集的。我们测量了所有标本的九个形态特征：总茎、张口、喙宽、喙深、跗骨、翼长、尾长、总长和重量。我们还有 257 个物种的生殖条件信息和 378 个物种的蜕皮信息。该数据集中包含的信息代表了南美洲约 20% 的哥伦比亚鸟类和约 11% 的鸟类物种丰富度。此数据集仅用于非商业用途。
