How can computers learn to recognize birds from sounds? The BirdNET research project uses artificial intelligence and neural networks to train computers to identify nearly 3,000 of the most common species of North America and Europe. You can record a file using the internal microphone of your iOS device and see if BirdNET correctly identifies the probable bird species present in your recording. Get to know the birds around you and help us to collect observations by submitting your recordings.

BirdNET is a joint project of the K. Lisa Yang Center for Conservation Bioacoustics at the Cornell Lab of Ornithology, and Chemnitz University of Technology.

dinosaurs are slick as heck ,

such a useful tool!

i am hard of hearing and often have trouble distinguishing between different species while birding. this tool has been incredibly valuable to me. possibly my favorite thing about this app is that it starts recording as soon as you open it; you don’t have to hassle with it at all, which is great for getting a quick ID. i also love that you can save clips to look back on later, which is especially helpful when you’re out in the woods and can’t get an internet connection right away. like others have said, the app is a bit glitchy, and it sometimes freezes even when i do have a good connection. overall though i haven’t been too frustrated by this app. it’s extremely helpful and it is typically quick and accurate in getting an ID. i’ve found myself recommending this app to everyone, from close friends to total strangers on the trails :)

Maine one ,

Great app, but....

I’ve been using the app for a week and it is very accurate for western Maine birds. Great for the high pitched warblers that are on the edges of my hearing range.

My biggest issue is that it freezes up and stops analyzing about every twenty analyses. At the times it’s frozen up (with the infinite spinning orb) there has been plenty of cell signal on my phone. Any suggestions of what to do in the field to correct this? Turning the phone off and on does not work. The only thing that works is to delete and reload the app. Big pain while in the field!

I agree with another reviewer that it would be useful to submit feedback when multiple birds have resulted in the analysis. Often it’s right on one but not on all. Seems this would be good to know.

Rhenish ,

Overall great despite some issues

First of all, this is a fantastic tool! You need to learn how to use it, but once you do it’s quite useful. Keep in mind, it’s far from perfect as a bird ID tool, as it often misidentifies with high certainty. You need to use it with other information if using it to ID. I wish it would use location and date information as Merlin Bird ID does to filter possibilities. For example, it was highly certain this morning’s yellow-green vireo was a red-eyed vireo; there’s no way it could be the red-eyed at my location this time of year. Duh!

There is one annoyingly missing feature: the ability to bulk delete observations. Or at least to swipe-delete observations. Right now it’s a 3-click process. Multiply that times tens or hundreds…
