About this app

What's that bird? Ask Merlin—the world’s leading app for birds. Just like magic, Merlin Bird ID will help you solve the mystery.

Merlin Bird ID helps you identify birds you see and hear. Merlin is unlike any other bird app—it's powered by eBird, the world’s largest database of bird sightings, sounds, and photos.

Merlin offers four fun ways to identify birds. Answer a few simple questions, upload a photo, record a singing bird, or explore birds in a region.

Whether you’re curious about a bird you’ve seen once or you’re hoping to identify every bird you can find, the answers are waiting for you with this free app from the renowned Cornell Lab of Ornithology.

WHY YOU’LL LOVE MERLIN
• Expert ID tips, range maps, photos, and sounds help you learn about the birds you spot and build birding skills.
• Customized lists of birds to find where you live or travel
• Merlin was created by bird experts for everyone.
• Merlin is global—look up any bird at any location.
• Keep track of your sightings—linked to eBird, a global database of more than 1 billion bird observations!


MACHINE LEARNING MAGIC
• Powered by Visipedia, Merlin Sound ID and Photo ID uses deep learning to identify birds in photos and sounds. Merlin learns to recognize bird species based on training sets of millions of photos and sounds collected by birders at eBird.org, archived in the Macaulay Library at the Cornell Lab of Ornithology.
• Merlin delivers the most accurate results thanks to experienced birders, who curate and annotate sightings, photos, and sounds, who are the true magic behind Merlin.

AMAZING CONTENT
• Choose bird packs that contain photos, songs, and calls, and identification help for anywhere in the world, including Mexico, Costa Rica, South America, Europe, Africa, the Middle East, India, Australia, Korea, Japan, China, and more.
• It’s available in your language. Merlin is available in English, Spanish, Portuguese, French, Hebrew, German, Japanese, Korean, Turkish, Simplified Chinese, and Traditional Chinese.

The Cornell Lab of Ornithology’s goal is to help you and millions of others to learn about birds. Our nonprofit mission to improve the understanding and protection of birds and nature is made possible by the generosity of Cornell Lab members, supporters, and citizen-science contributors.

All around Great APP! Enjoyable and easy to use. Possibly make it easier to set up for Life List and all capabilities of the APP. Great audio, layout, accuracy and images. I would rate this app higher if I could. Got us out of the house and exploring for sightings just clean fun. Well done.

I adore this app, I find it more useful for ID than even the best field guides available. One thing I think the app would benefit from is an offline mode. It's somewhat tedious to have to sit through the "please wait" screen when you're birding somewhere without cell service. Additionally, an option to download your own sound recordings would be appreciated.

The new version keeps shutting down! Sometimes the timer keeps going, but it stops recording. When it does that, I can usually push "stop" and save my record. But other times, it won't do anything; no button works and I have to restart my phone. In those cases, I lose my record, unless I wait a minute or two. In that case, today, my record was saved. This is SO frustrating!

What's new

Sound ID is better than over, with additional birds for the United States, Canada and now the common species of Europe, northern Africa and the Middle East! Record the birds you hear, and watch real-time results show up on the screen to help guide you to the correct identification.
