One Tech Tip: Ditch the chatbots and take your AI nature apps on a birdwatching hike

Key Points

• The Merlin Bird ID app utilizes artificial intelligence to help users identify bird species by analyzing live sound recordings from their surroundings.
• AI nature apps like Merlin and iNaturalist encourage a new demographic of users, particularly 20- and 30-year-olds, to engage with nature and contribute to citizen science efforts.
• While built-in AI features on smartphones aid in identifying plants, they lack the community and accuracy benefits offered by dedicated apps like iNaturalist.
• It's essential to exercise caution with AI-generated plant identifications, as not every suggestion is reliable, especially when it comes to identifying edible plants.

I didn't notice the scarlet tanager until the alert appeared on my phone: “Merlin heard a new bird!”

Despite its brilliant plumage — jet-black wings on a crimson body — the songbird can be a hard one to spot in a forest because it prefers to stay high in the canopy. It sounds a little like a robin to an untrained ear.

But the free Merlin Bird ID app detected a scarlet tanager was likely nearby by using artificial intelligence to analyze my phone’s live sound recording. I paused my hike, quietly scanned the treetops, saw the bird as it kept singing and clicked a button to add the species to my growing "life list" of bird sightings. Digital confetti burst on my screen.

Like a real-world version of Pokémon Go, a gotta-catch-'em-all drive to add to my Merlin list has helped me find a great kiskadee in Mexico and a rusty-cheeked scimitar-babbler in the Himalayas. But sometimes the greatest revelations are close to home, as more AI nature app users are starting to discover.

“Our stereotypical demographic five years ago would have been retired people and already-avid birders,” said the Merlin app's manager, Drew Weber, of the Cornell Lab of Ornithology. “Now we’re seeing a lot of 20-and-30-year-olds posting stuff on their TikTok or Instagram.”

Are you a bird person now?

“Am I a bird person now? Am I a bird person now?” exclaims one incredulous TikTok user whose Merlin app detected a tufted titmouse, a cardinal and a Carolina wren within five seconds of her switching on the app.

Another video shows Seattle Seahawks quarterback Sam Darnold gushing about the technology.

“That was a northern mockingbird,” says a smirking Darnold, then 27 and now 28, holding his phone up high while sitting in an outdoor lounge chair.

The app isn't always perfect, and mockingbirds — because they mimic other bird sounds — can sometimes confuse the AI. Was that really a great horned owl that flew over your home and hooted while you left the app on record by the window screen? Maybe, maybe not.

“Low-frequency sounds can be challenging because there’s other low frequencies, like cars driving past, that can trick it,” Weber said.

AI nature apps are not just for the birds

Built-in computer vision technology on newer iPhones and Android devices makes it easier to identify plants and other creatures without having to download an app. Simply look at the flower you just photographed and — on iPhones — a leaf icon appears that, when clicked, can suggest the species.

But their AI accuracy isn't always the best for more obscure fauna and insects — and they are missing the immersive community and citizen science experience that free apps like Merlin and the image-based iNaturalist offer.

Every observation submitted to iNaturalist, run by a nonprofit, and Cornell's Merlin is potentially helping with conservation research as animal extinctions and biodiversity loss accelerate around the world.

iNaturalist’s executive director, Scott Loarie, sees someone's urge to identify a backyard plant as just the start of their engagement with the app. The nonprofit also owns a sibling app, Seek, that is kid-friendly and less complicated.

“Our strategy is really building this community of really passionate, engaged nature stewards who are not only learning and sharing knowledge about nature, but they’re actually huge engines for creating biodiversity data and conservation action,” Loarie said.

Submit an incorrect ID suggested by iNaturalist's AI and someone with real expertise will often politely correct you. Once there's enough consensus, you'll be notified that your observation has made it to “research grade.”

Don't use AI apps to pick strange berries (but I did)

On the search for huckleberry, a favorite of jam makers and grizzly bears, I kept iNaturalist handy on an August hike through the Wyoming wilderness.

And while I had a hard time finding a huckleberry bush, iNaturalist helped me discover other fruits: a type of serviceberry known as the saskatoon; the big-leafed, raspberry-like thimbleberry and the vibrant orange berries of the Greene’s mountain-ash, a type of rowan. After cross-checking many other resources, I tasted all three. The first two were sweet, the last bitter and disgusting.

“You should never trust any sort of automatic ID or a stranger on the internet for something as important as edible plants,” Loarie said. "So, I definitely don’t want to endorse that. But I’d certainly endorse getting to know plants and animals.”

One common thread in the TikTok videos is the joy of discovering the variety of wildlife that live among us, if we pay enough attention.

Elsewhere, I've found it particularly helpful in identifying things to avoid – poison ivy, poison oak, disease-carrying ticks – and things to destroy, like a nymph of the invasive spotted lanternfly that’s now infesting at least 19 U.S. states.
