Record with your phone
Capture songs and calls directly in the app using the device microphone.
BirdNerd App
Identify birds from their sounds
Record a song or call with your phone. BirdNerd analyses the recording and suggests the most likely species.
Available for Android
What BirdNerd can do
Built for real-world bird sounds
BirdNerd is designed for recordings made outdoors, where several species and background sounds may be present at the same time.
Use field recordings
Analyse sounds recorded in natural and urban environments, including background noise.
Find several species
BirdNerd can suggest multiple birds when more than one species is heard in a recording.
Recognise more than songs
Identification can use songs, calls and other characteristic bird sounds.
Current coverage
Common European species
BirdNerd currently focuses on species commonly encountered across Europe.
Recognition outside the supported area, or for uncommon species, should be treated with additional caution.
How it works
From field recording to species suggestions
BirdNerd sends the recording to its server, where a neural network analyses the sound and returns likely matches.
-
Record a short sample
Capture a bird song, call or other characteristic sound using the phone microphone.
-
Send it for analysis
The recording is processed by BirdNerd’s server-side recognition model. An Internet connection is required.
-
Review the suggestions
The app returns one or more likely species. Results are probabilistic and should be used as identification hints.
Available on Android
Take BirdNerd into the field
Record bird sounds, review likely matches and keep your observations close at hand.
Requires Android and an Internet connection for identification.
About the project
Project status
BirdNerd remains available on Android, and the core recognition service is being maintained.
Active development of new user-facing features has been paused while the next stage of the project in field bioacoustics is being explored.
The experience, infrastructure and recording collections behind BirdNerd may help shape a broader system for analysing natural soundscapes.
Existing Premium users keep access to their paid benefits while the service remains available. Subscriptions can be managed or cancelled through Google Play.
