birdnetR

birdnetR integrates BirdNET, a state‐of‐the‐art deep learning classifier for automated (bird) sound identification, into an R-workflow. This package will simplify the analysis of (large) audio datasets from bioacoustic projects, allowing researchers to easily apply machine learning techniques—even without a background in computer science.

birdnetR is an R wrapper around the birdnet Python package. It provides the core functionality to analyze audio using the pre-trained 'BirdNET' model or a custom classifier, and to predict bird species occurrence based on location and week of the year. However, it does not include all the advanced features available in the BirdNET Analyzer. For advanced applications, such as training custom classifiers and validation, users should use the 'BirdNET Analyzer' directly. birdnetR is under active development, and changes may affect existing workflows.

Installation

Install the released version from CRAN:

install.packages("birdnetR")

pak::pak("birdnet-team/birdnetR")

Example use

This is a simple example using the tflite BirdNET model to predict species in an audio file.

# Load the package
library(birdnetR)

# Initialize a BirdNET model
model <- birdnet_model_tflite()

# Path to the audio file (replace with your own file path)
audio_path <- system.file("extdata", "soundscape.mp3", package = "birdnetR")

# Predict species within the audio file
predictions <- predict_species_from_audio_file(model, audio_path)

# Get most probable prediction within each time interval
get_top_prediction(predictions)

Funding

This project is supported by Jake Holshuh (Cornell class of '69) and The Arthur Vining Davis Foundations. Our work in the K. Lisa Yang Center for Conservation Bioacoustics is made possible by the generosity of K. Lisa Yang to advance innovative conservation technologies to inspire and inform the conservation of wildlife and habitats.

The development of BirdNET is supported by the German Federal Ministry of Education and Research through the project “BirdNET+” (FKZ 01|S22072). The German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety contributes through the “DeepBirdDetect” project (FKZ 67KI31040E). In addition, the Deutsche Bundesstiftung Umwelt supports BirdNET through the project “RangerSound” (project 39263/01).

Partners

BirdNET is a joint effort of partners from academia and industry. Without these partnerships, this project would not have been possible. Thank you!
