BirdNET provides the fastest route to an ID by processing recordings with AI, making it the easiest method overall. The Peterson Field Guide helps you learn the visual rhythms of bird calls through hands-on analysis, and the Audio Birding North America Facebook group is solid for rare or confusing sounds where community expertise shines.
What you need
- BirdNET app or access to BirdNET website
- Peterson Field Guide
- Audacity software or SpectrumView app
- Audio recording of mystery bird
Steps
- Upload your recording to BirdNET for immediate analysis. Android users can use the free BirdNET app, while iOS users should upload recordings from iCloud to the BirdNET website. The system converts audio to a spectrogram using Fast Fourier Transforms and applies image processing and artificial intelligence to identify the bird. You can expect results within minutes.
- Use the Peterson Field Guide to study sound patterns more deeply. This resource contains over 3600 spectrograms. Create a spectrogram of your mystery sound using Audacity, or use the SpectrumView app on an iPhone. Match your visual index against the guide. This process takes several minutes to hours but is recommended for learning the nuances of bird sounds.
- Reach out to the Audio Birding North America group on Facebook for difficult cases. Convert your audio file to a video format before uploading. This method is useful for specific and rare bird identifications, though you may need to wait hours for an accurate identification from the community.

BirdNET does not list an iOS app here; use the website with iCloud uploads instead.
Rare or complex calls
AI analysis might struggle with uncommon species. For these cases, the Facebook group is the better choice for accurate help.
