01
Start with a clear observation
Use a well-lit photo that shows the bird’s shape and plumage, or record several seconds of a call away from wind and human voices.

Identify birds with more than a name
BirdLens combines an AI identification tool with a field guide designed for checking a result. Start from a photo or sound in the app, then compare visible features, calls, habitat and range before recording your observation.
02
Compare likely species
Treat an AI match as a starting point. Check size, colors, season, habitat and distribution against the species guide.
03
Learn in your language
Browse common and scientific names, photos, sounds and observation features in English, Chinese, German, Spanish, Italian and French.
A practical companion for responsible birdwatching
Identification results can vary with image quality, background noise, location and season. BirdLens presents likely matches for educational use and encourages users to verify difficult records with multiple field marks or a local expert. Observe wildlife from a respectful distance and avoid disturbing nests or playing calls repeatedly.
Use the field guide to verify an identification
A useful identification explains why a species fits. BirdLens species pages can include common and scientific names, photographs, recordings, seasonal observation features, taxonomy, breeding and non-breeding ranges, migration patterns and population information. Availability varies by species. Comparing several independent clues is more reliable than choosing a result from color alone, especially for juveniles, females and closely related species.
Choose photo or sound based on the situation
Photos work best when the bird is visible long enough to capture its proportions, bill, wings, tail and major plumage marks. Sound can be more useful when a bird is hidden by foliage, but recordings should preserve the repeated phrase and avoid clipping. Location and date provide essential context because many species move seasonally and similar birds may occupy different ranges.
