Is there an AI for identifying birds by song?

Bird song identifier apps: how they work and what is free

Open the app, tap record and hold the phone toward the sound. A scrolling spectrogram draws each voice as a shape, and names appear as the model recognizes those shapes, checked against the birds that are likely where you are on that date. The leading free app knows more than 2,000 species by ear: most birds of the US, Canada and Europe, plus the common, widespread birds of India and Central and South America. Outside those regions it will miss most of what you hear.

Price is not what separates the good ones. The first two picks above are free, have no paid tier and keep working without a signal. Paying buys extras, not accuracy: the second-opinion app charges from $14.99 a year to save recordings and import files, and the box that listens to your yard around the clock costs $269 with a year of premium features, then $59 a year or a free tier.

What bird is this sound? Naming a recording or a video

If the bird is gone but you have a recording, you can still get a name. The leading free app imports files: tap import on its sound screen, or share the file to it from another app, and it lists the likely birds. It takes standard audio such as mp3, m4a and wav, and works best on clips of 10 minutes or less. Another free pick does the same on the phone with no connection, and can run a whole batch of files at once.

A clip from a video needs one extra step. The importers ask for audio files, so save the soundtrack as an audio file first, keeping the stretch where the bird calls and as little talking, wind or traffic as you can. On a computer, the FAQ below covers doing it in a browser.

How to identify birds by sound and get a better match

Most misses start with the recording, not the model. Get as close as you can without disturbing the bird, then stand still and stay quiet: you are the closest thing to the microphone, so your rustling comes out louder than the song. Keep the mic uncovered, move away from traffic if you can, and record for at least 30 seconds while the bird keeps singing. A tiny clip-on microphone barely helps; a directional shotgun mic does.

Then treat every name as a suggestion. Play the example recordings side by side with yours, check the range map and the season, and be suspicious of a rare bird in an ordinary backyard. Seeing the singer is the only real confirmation. Compare calls through earphones instead of playing them out loud, which can pull a bird off its territory or its nest.

Bird identifier by picture, when you can see it

If the bird sits still long enough for a photo, take one: a picture often settles what a song cannot. The first pick on the list also identifies birds from photos, with a model trained on more than 6 million of them, and it no longer needs you to crop. Upload the shot, add where you took it, and you get a ranked list of likely species.

Sound ID grows more slowly than photo ID: a species can only be added once birders have uploaded at least 150 recordings of it. No photo and no recording at all? The same app has a question mode, covered in the FAQ below. For leaves and flowers instead of feathers, see identifying a plant from a photo.

identifying birds by song: quick answers

Is there a free bird song identifier app?

Yes, and the best ones are free. The first two picks above cost nothing, have no paid tier and identify birds by sound offline; the first asks you to confirm an email address after a five-day trial. The nonprofit behind it says it will never ask for a card number, so if a bird app with a similar name does, you are in a different app.

Is there an app like a song recognizer, but for birds?

Yes, and it works much the same way: hold the phone up and names appear while the birds sing. Unlike a music recognizer, it can list several birds singing at once, and it narrows the matches to species likely where you are. For a tune stuck in your head rather than a bird outside, see finding a song by humming.

How accurate are bird sound identifier apps?

Good on common birds, and still short of a trained ear. In a 2025 peer-reviewed field test in Maine, human observers logged 72% more detections than the leading free app, and the birds the app did name were right 86% of the time, against 92% for the humans. Two phones running it side by side disagreed on 57% of the counts, and in a 2024 study of ranch recordings in Texas, mockingbirds caused about 31% of its false detections.

Can you identify a bird by description?

Yes. The first pick has a question mode: give it the date and place, the bird's size, its main colors and what it was doing, and it ranks the birds reported there at that time of year. If nothing fits, move the size up or down a notch and enter only the colors you are sure of.

Can I identify a bird song online without an app?

Yes. One of the free picks has a browser page where you drop in a WAV or MP3 file, or record from the microphone for up to five minutes, and it lists the likely species in three-second slices. The analysis runs in your browser, so nothing is uploaded, and you can download the results as a CSV file. The leading app's sound ID, by contrast, works only on phones and tablets.
