Passive acoustic sampling data of the Colección de Sonidos Ambientales Mauricio Álvarez-Rebolledo - Instituto Humboldt (IAvH-CSA) during 2018 and 2019 in Colombia.

We present the dataset of passive acoustic sampling events deposited in the Colección de Sonidos Ambientales Mauricio Álvarez-Rebolledo at the Humboldt Institute (IAvH-CSA) during the years 2018-2019. The acoustic sampling events were generated from different projects, including Colombia Bio, Santander Bio, Boyacá Bio, Lisama, Riqueza Natural, and occasional events collected during this time. In total, 44,704 sampling events are deposited in the collection, corresponding to 1 minute of automatic recording sampled at a 44.1 kHz sampling rate and 16-bit resolution. The recording schedules correspond to 1 minute every 5, 10, or 30 min throughout the day, during 1 to 20 sampling days, across 79 localities in Colombia. The geographical coverage includes the departments of Bolívar, Boyacá, Caquetá, Cundinamarca, Meta, Santander, and Sucre. The present information was collected within the framework of the passive monitoring methodology established by the Humboldt Institute .

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.
