Body mass data set for 1,317 bird and 270 mammal species from Colombia.

Body mass is one of the most important phenotypic attributes in animal ecology and life history. This trait is widely used in the fields of ecology and macroevolution, since it influences physiology, morphological functions, and a myriad of ecological and social interactions. In this data set, our aim was to gather a comprehensive bird and mammal body mass data set from northern South America. We report body mass, discriminated by sex, for 42,022 individual birds and 7,441 mammals representing 1,317 bird species (69% of Colombia's avifauna) and 270 mammal species (51% of Colombian mammals) from the Neotropics. The data were sourced from vouchers collected between 1942 and 2020 and from individuals captured and released at banding stations over the last two decades for birds (2000-2020) and the last decade for mammals (2010-2020), by 10 research groups and institutions in Colombia. This data set fills gaps identified in other similar databases, as it focuses on northern South America, a highly diverse Neotropical region often underrepresented in morphological data sets. We provide wide taxonomic coverage for studies interested in information both at regional and local scales. There are no copyright restrictions; the present data paper should be appropriately cited when data are used for publication. The authors would appreciate learning about research projects, teaching exercises, and other uses given to this data set and are open to contribute in further collaborations using these data.

Dataset on audio records of animals from the northeast Andes of Colombia II: The vertebrate sounds of Santander department.

Colombia holds one of the most spectacular biodiversity of the world. Yet, vast aspects of this biodiversity are still poorly inventoried. One of the least known aspects of Colombia's biodiversity is the sound produced by its animals, even for the most conspicuous ones, the vertebrates. Here we reviewed and compiled the sound records available for the Department of Santander, a region in the North-East of Colombia, gathering the sound records of birds, anurans, mammals, and fishes. By conducting a detailed review in the environmental sound collection of the Humboldt Institute, the Macaulay Library of the Cornell Lab of Ornithology and Xeno-canto platform of the Naturalis Biodiversity Center, we present the first dataset of vertebrate sounds information from the Santander department. We selected recordings with a taxonomic resolution up to species and complete metadata information. Using latitude and longitude information, we assigned each recording to one of the six biotic units reported for Santander. We found a total of 1499 recordings, which belong to six biotic units: Guane-Yariguíes (597), Middle Magdalena Valley and Mompox Depression (484), High Andes Eastern Cordillera (167), Nechí-San Lucas (150), Middle Magdalena Eastern Cordillera (95), Catatumbo (6). This dataset can have a wide scope of applications, from basic scientific questions, to analyses made by decision makers regarding conservation strategies, to support biodiversity-based economies such as ecotourism.

Dataset on audio records of animals from the northeast Andes of Colombia I: The bird sounds of Boyacá department.

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.
