BIRDeep Audio Annotations
The BIRDeep Audio Annotations dataset is a collection of bird vocalizations from Doñana National Park, Spain. It was created as part of the BIRDeep project, which aims to optimize the detection and classification of bird species in audio recordings using deep learning techniques. The dataset is intended for use in training and evaluating models for bird vocalization detection and identification.
The research code and further information is available at the Github Repository.

Uses
Direct Use
The dataset is intended for use in training and evaluating models for bird vocalization detection and identification. It can be used to automate the annotation of these recordings, facilitating relevant ecological studies.
Dataset Structure
The dataset includes audio data categorized into 38 different classes, representing a variety of bird species found in the park. The data was collected from three main habitats across nine different locations within Doñana National Park, providing a diverse range of bird vocalizations.
The distribution of the 38 different classes through the 3 subdatasets (train, validation and test) is the following:
Data Files Description
There are 3 .CSV
files that contain all the metadata related to each split of the dataset (train, validation, and test). Each of these .CSV
files includes the following information. Each row represents one annotation (an annotated bird song). There might be more than one row per audio.
- path: Relative path from the
Audio
folder to the corresponding audio. For images, change the file format to.PNG
and use theimages
folder instead of theAudios
folder. - annotator: Expert ornithologist who annotated the detection.
- recorder: Code of the recorder; see below for the mapping of recorder, location, and coordinates.
- date: Date of the recording.
- time: Time of the recording.
- audio_duration: Duration of the audio (all are 1-minute audios).
- start_time: Start time of the annotated bird song relative to the full duration of the audio.
- end_time: End time of the annotated bird song relative to the full duration of the audio.
- low_frequency: Lower frequency of the annotated bird song.
- high_frequency: Higher frequency of the annotated bird song.
- specie: Species to which the annotation belongs.
- bbox: Bounding box coordinates in the image (YOLOv8 format).
Each annotation has been adapted to the YOLOv8 required format, which follows the same folder structure as the image folder (which is the same as the Audio
folder) for a labels folder. It contains a .TXT
file for each image with one row per annotation, including the species and bounding box.
Dataset Creation
Curation Rationale
The dataset was created to improve the accuracy and efficiency of bird species identification using deep learning models for our study case (Doñana National Park). It addresses the challenge of managing large datasets of acoustic recordings for identifying species of interest in ecoacoustics studies.
Source Data
Data Collection and Processing
Audio recordings were collected from three main habitats across nine different locations within Doñana National Park using automatic audio recorders (AudioMoths). See map below.
The names of the places correspond to the following recorders and coordinates:

Data producers
The data was produced by researchers from Estación Biológica de Doñana and Universidad de Córdoba. A research center and University at the south zone of Spain, close to the study region, National Park of Doñana.
Annotations
Approximately 500 minutes of audio data were annotated, prioritizing times when birds are most active to capture as many songs as possible, specifically from a few hours before dawn until midday.
Annotation process
Annotations were made manually by experts, resulting in 3749 annotations representing 38 different classes. In addition to the species-specific classes, other general classes were distinguished: Genus (when the species was unknown but the genus of the species was distinguished), a general "Bird" class, and a "No Audio" class for recordings that contain only soundscape without bird songs.
As the Bird Song Detector only has two classes, labels were reclassified as "Bird" or "No bird" for recordings that include only soundscape background without biotic sound or whether biotic sounds were non-avian.

Bias, Risks, and Limitations
The dataset may have biases due to the specific ecological context of Doñana National Park and the focus on bird vocalizations. It also exhibits class imbalance, with varying frequencies of annotations across different bird species classes. Additionally, the dataset contains inherent challenges related to environmental noise.
Recommendations
Users should be aware of the ecological context and potential biases when using the dataset. They should also consider the class imbalance and the challenges related to environmental noise.
More Information
This dataset incorporates synthetic background audio, which has been created by introducing noise and modifying the original audio intensities. This process, known as Data Augmentation, enhances the robustness of the dataset. Additionally, a subset of the ESC-50 dataset, which is a widely recognized benchmark for environmental sound classification, has also been included to enrich the diversity of the dataset. These additional datasets can be excluded as they are in separate folders within the root folders for audios, images, and labels (Data Augmentation
and ESC50
). Annotations for these datasets should be removed from the CSV files if they are not used in processing the dataset.
The synthetic audio was created using a Python script that took the original background audio recordings and modified their intensities and shifted them. This method allowed for the introduction of noise and variations in the audio, simulating different recording conditions and enhancing the dataset's robustness.
