You’ll feel like you have a superpower as Merlin detects and displays those difficult-to-discern calls, and checking what Merlin hears can be a great way to train your own ears.Ī Baltimore Oriole may be distinctive looking, but songs of different birds vary making this species' sound ID a challenge for Merlin. Birds that are singing in the distance-or ones with stratospheric songs such as Blackpoll Warbler, Blackburnian Warbler, and Cedar Waxwing-can be hard to pick up and even harder to ID. Use Merlin as a Set of “Super Ears”: Some bird songs are easier to hear than others. Weber says that for many common species, such as Northern Cardinal, White-throated Sparrow, Song Sparrow, and Dark-eyed Junco, Merlin should be able to make the ID from a clear recording. Sound ID is a great tool to help you learn bird songs and calls.ĭecipher Tricky Chip Notes: As if bird songs weren’t difficult enough, birds often communicate with little more than a few short, unmusical chip notes. And because you can go back and dial in to the sound and image of each bird that was identified, you can listen again and again. Merlin can tease apart these threads and reveal the identity of each individual in the soundscape. Try these specific uses of Sound ID, recommended by Merlin project coordinator Drew Weber, to make your birding by ear even more enjoyable:ĭecode the Dawn Chorus: In spring and early summer, mornings overflow with bird song-sometimes a dozen or more species at once. If you’re still having trouble installing or using Sound ID, check the Merlin help pages. And you can save each bird species Merlin helps you identify to your life list using Merlin’s Save My Bird feature. Merlin automatically saves each recording to a folder on your device so you can access it anytime-and those recordings can be deleted or uploaded elsewhere if storage space is an issue. That way you can see and hear what separates it from other birds you’re hearing, and easily compare each sound to recordings from Merlin’s sound library. Or tap on any of the species in Merlin’s list of possibilities, and you’ll zip back to the point in the recording where that sound occurs. When you’ve finished recording, you can go back and select a section to see which species are singing which songs. If Merlin has trouble identifying your bird, try getting closer without disturbing it, and check these tips to help you minimize extraneous noise. On your phone screen you’ll see a list of possible species, complete with a thumbnail photo of the bird and examples of songs and calls for each species.Īdjust Your Setup If Necessary. Merlin will instantly start listing the birds it hears. If you’re hearing bird song, just select Sound ID from the main menu and press record. If you already have Merlin installed on your phone, tap Get Sound ID.įind a Singing Bird (or Birds). To get the new Sound ID feature, simply download our free Merlin Bird ID app and follow the prompts. Merlin Sound ID is powered by eBird observations and recordings, and it’s easy to use. This pioneering sound-identification technology is integrated into the existing Merlin Bird ID app, meaning Merlin now offers four ways to identify a bird: by a sound, by a photo, by answering five questions about a bird you saw, or by exploring a list of the birds expected where you are. “So just like Merlin can identify a picture of a bird, it can now use this picture of a bird’s sound to make an ID,” Van Horn says. “Each sound recording a user makes gets converted from a waveform to a spectrogram-a way to visualize the amplitude, frequency, and duration of the sound,” Van Horn says. More about sound ID coverage.)Īutomatic song ID has been a dream for decades, but analyzing sound has always been extremely difficult. The breakthrough came when researchers, including Merlin lead researcher Grant Van Horn, began treating the sounds as images and applying new and powerful image classification algorithms like the ones that power Merlin’s Photo ID feature. (Note: as of late 2022, the sound ID feature could identify 870 species in the U.S., Canada, Western Palearctic (Europe), and Neotropics. and Canada, with that number set to expand rapidly in future updates. At the time of the feature’s launch, Merlin can recognize the sounds of 400+ species from the U.S. Today, the question got much easier: the Cornell Lab’s Merlin Bird ID app can now identify bird sounds. And it’s usually followed up by the question: What was that bird? It’s an almost universal feeling: the thrill of hearing a mysterious new bird song.
