Ratings and Reviews
A birder’s best friend
Birdwatchers know life before Merlin, and life after Merlin. Carrying a field guide on your phone, localised to the region where you’re birding, was unthinkable just a few years ago. Although the photo ID and sound ID need improvement, they’re getting better as more and more data gets added to the Cornell Labs database. The data packs are frequently updated and that’s a great thing.
One stop destination for all bird watchers
A big thank you to the good folks at Cornell for hatching the Merlin Bird ID app to life! The app’s easy user interface enables amateur birdwatchers like me to keep coming back to it again and again.
It’s concise and compact compendium of knowledge holds my attention. Bird detection tool using AI is a breakthrough of sorts as I haven’t come across any another app that has this feature. Keep it up!
Very user friendly app
I have started using this app since two days ..... I have to still record all the birds in my vicinity...but what I found was that the app is so user friendly..... you can know about a lot of birds around you ... you can easily identify them based on the pictures and their calls .... amazing idea! and kudos to the developers of this app
