Imagine a world where technology doesn’t pull you away from nature but instead brings you closer to it. That’s the promise of Merlin Bird ID, an app that’s revolutionizing the way we connect with the natural world—one birdsong at a time. But here’s where it gets controversial: while some hail it as a game-changer for birdwatching, others worry it might replace the joy of learning firsthand. Let’s dive in.
When Natasha Walter, a writer and human rights activist, first became curious about the birds in her London garden, she found herself recording their songs on her phone and painstakingly comparing them to online clips. That all changed when a friend introduced her to Merlin Bird ID, a free app developed by the Cornell Lab of Ornithology. To her surprise, what she thought were female blackbirds were actually song thrushes and mistle thrushes. ‘This is how bad a birder I was,’ she admits with a laugh. Now, she’s hooked. ‘Merlin is wonderful—it’s been a joy to me,’ she says. ‘This is what AI and machine learning should be used for. It’s the one good thing!’
Merlin is having its moment in the spotlight. With over 33 million downloads across 240 countries and territories, it’s become a global phenomenon. Britain alone boasts more than 1.5 million users in 2024, an 88% jump from the previous year. Every month, new users flock to the app, drawn by its sound identification feature launched in 2021. Trained to recognize the songs of over 1,300 bird species—with more added twice a year—Merlin works by analyzing the unique patterns songs create on spectrograms. It’s like teaching a machine to read nature’s sheet music.
For beginners or those without a bird-savvy friend, Merlin has become more than just an app—it’s a mentor. Walter initially worried she’d rely too heavily on it, but she’s found it enhances her learning journey. ‘Now I make guesses and use Merlin to confirm my hunches,’ she explains. ‘It’s perfect for latecomers to birdwatching who don’t have a guide.’
Angela Townsend from Bedfordshire can relate. After a nightingale walk left her overwhelmed by the evening chorus, she turned to Merlin. ‘Warblers used to be just ‘little brown jobbies’ to me, but now I can spot Cetti’s warblers and willow warblers without the app,’ she shares. Mary Novakovich, author of My Family and Other Enemies, uses it while traveling in Croatia, her parents’ homeland. ‘It connects you to the natural world in a way that feels personal,’ she says. ‘It’s part of what makes life joyful.’
But Merlin isn’t without its quirks. Twelve-year-old Kasper Wall, a budding birder from Norfolk, recalls the app once identifying North American species like the northern cardinal in his British garden. ‘I think it was still figuring out where we were,’ he says with a grin. Even so, he enjoys testing its limits, mimicking bird calls like a curlew or barn owl to see if it can keep up. ‘It’s good, but it’s no Nick Acheson,’ he quips, referring to the renowned naturalist.
And that’s where the debate heats up. While Merlin is a powerful tool, some worry it could discourage active learning. Nick Acheson himself welcomes the app but cautions, ‘There’s no substitute for someone teaching you how a birdsong feels and helping you connect with it emotionally.’ He’s noticed glitches, like Merlin mistaking a chaffinch call for a redstart, leading users to believe they’ve spotted a rare bird. John Williamson, a guide for Norfolk Wildlife Trust, has seen similar issues. ‘Merlin can’t account for habitat,’ he explains, pointing out instances where the app identified unlikely species in specific environments.
Yet, Williamson still calls it a ‘good tool’ and applauds its ability to draw people into nature. He shares the story of someone with acute anxiety who found solace in using Merlin, rediscovering the calming effects of outdoor exploration. ‘It’s impressive how an app can empower people to engage with nature,’ he reflects.
Research backs this up: birdsong has proven mental health benefits, fostering a lasting sense of well-being. For millions, Merlin is more than an app—it’s a gateway to mindfulness and connection. ‘It reminds you that birds are part of your daily life,’ Walter notes. ‘You don’t need to set aside time for birdwatching; you might just hear a song in the park and feel that joy.’
But here’s the question: Is Merlin a stepping stone to deeper engagement with nature, or does it risk becoming a crutch? Does it enhance our connection to the natural world, or does it subtly replace the art of observation? Share your thoughts in the comments—let’s keep the conversation chirping!
