Merlin tells you the answer. BirdsongBook trains your ear so you know it yourself.
A quiet field guide for common birds and their voices — song mnemonics, calls, visual marks, range, and the mistakes that trip people up. Flashcard practice, a field notebook, and reference audio, all on your device. No account. No ads. Works offline.
What it does
• Reference audio — hear each bird's song and call, with full recording credits.
• Song mnemonics — remember every voice ("cheer-up, cheerily, cheerio").
• Flashcard ear-training — spaced practice that builds durable skill.
• Field notebook — save sightings and confidence, kept on your device.
• AI field coach — ask how to separate look-alike and sound-alike species.
