Abstract
We conducted passive acoustic surveys for galagos (Family: Galagidae) in 38 cocoa agroforests in the Ashanti Region of Ghana, and we trained a YOLOv5 convolutional neural network model using a dataset of galago vocalisations from across sub-Saharan Africa to enable automatic detection of galago calls. Despite a high rate of false-positive detections, our galago detector model confirmed the presence of at least one species of western dwarf galago (Galagoides) in four cocoa agroforests, each situated > 4 km from the nearest forest reserve. These represent the first scientific records of galagos in cocoa agroforestry systems, although local ecological knowledge likely predates these observations. This dataset consists of the one-minute long audio files containing the detected calls of galagos in four seperate cocoa agroforests.

Description of the data and file structure
Passive acoustic surveys for galagos were conducted in 38 cocoa agroforests in the Ashanti Region of Ghana using Audiomoth devices. Each device was deployed for approximately two weeks and set to record for the period 18:00 – 05:00 at a 384 kHz sampling rate with mid-gain settings. After, we trained a YOLOv5 convolutional neural network model using a dataset of galago vocalisations from across sub-Saharan Africa to enable automatic detection of galago calls. This galago detector was then used to scan through all of our acoustic data for instances of galago vocalisations.

Description: All four files are 60-second long .wav files. They contain the galago vocalisations from the four farms upon which we were able to confirm the presence of galagos. File names contain the date of recording (e.g., 20241104), the time of the recording (e.g., 214000), and the time interval within the file at which the galago vocalisation can be heard (eg., 25 s).
Code/software
Any software capable of playing back .wav audio files can be used to listen to the recordings.
