Dataset of passive acoustic monitoring at the Nature Reserve Los Yátaros, Gachantivá, Boyacá, Colombia

Abstract

Passive acoustic monitoring is a technique in which acoustic sensors are placed with a particular recording setting, without interference from the observer. Despite the recent interest, many places in the Neotropics still do not have information on acoustic activity. Such acoustic sampling events would contribute to answer different questions about the acoustic diversity in the Neotropics. We present the dataset of passive acoustic sampling events during the first semester of 2020, at the Natural Reserve Los Yátaros, 6 km away of Gachantivá, Boyacá, Eastern Andes of Colombia. Sampling consisted of installing six AudioMoth acoustic sensors, two at each sampling site (n=3). We programmed all acoustic sensors to record 1 min every 30 minutes throughout the day (00:00-23:30) to audible spectrum (0 Hz-16 kHz), and at night (16:30-06:00) to ultrasound spectrum (up to 192 kHz). The monitoring was conducted from March 1 to May 2, 2020, gathering 12 447 recording, 9055 audible and 3392 ultrasound recordings.
