Description

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.

Loads of fun

Let me begin by stating I never use the original function of describing the bird I see. If I can see it that we’ll, chances are I can identify it without Merlin. The same goes with the photo ID feature—if I can get close enough and get a good enough look , I can ID the bird as well as Merlin can. I have tested out the photo ID, and I believe it would be a useful tool for beginners. Be aware that it’s not perfect: it has just as hard a time distinguishing between sharp-shinned and Cooper’s hawks as I do. Where the app really shines is in the sound ID. At first I was a little skeptical. One of the first times I used it it thought that one bird was both a common raven and an American crow. Same thing with some gulls. It thought there was both a California and Herring gull. I eventually found one I could call a California, the Herring gull never materialized. It also thought there was a tundra swan, but upon reviewing the recording, there was nothing there, and definitely no swan within my sight. The more I have used it, however, the more confident I become in its ID power. Generally, if Merlin disagrees with what I thought the sound was, I’ll try to track it down and find it. And more often than not, I find what Merlin told me was there. But the most fun I have had with this app was watching a northern mockingbird singing while Merlin picked out thirteen different bird songs that one mockingbird had learned and incorporated into its repertoire.

Great for a beginner like me

I love birds and want to learn more about them. I have been hesitant to join birdwatchers as I’ve heard via birder email lists the experienced birders can be impatient and critical of newbies and also make it hard for newbies to join any groups. It’s like breaking into a click. That said, I felt I needed to learn before I even got started so I tried Merlin ID. I have used all 3 tools and find each one useful. I’m most excited about the sound ID though. This app is not perfect and you should question a match that seems questionable, like if it gives you a “rare” match. Do some research by listening to the call options to see if the match is authentic. This app also doesn’t recognize every bird. But, when there isn’t a match just submit the recording to Merlin so they can further improve the app. It is constantly improving and can only do that if we all help out. One day, I heard a bird but couldn’t see it. The sound tool identified the bird so then I knew what to look for and sure enough, I was able to visually identify said bird! I was super excited and encouraged. I also enjoy reading about each bird, the various photos and learning the different calls and songs. I’ve begun to share this with my daughter and grandkids when we take walks. My grandson lights up when he is able to see photos of the birds he is hearing and he’s only 2.5. Fun for the whole family!

Amazing tool, but a few minuscule issues

This app is amazing. I use it every time I go bird watching, and it is far more efficient than most of the manuals I own. However, it is not without its minor faults.
The first and most blaring is the fact that Isee many birds with many more than only 3 colors, and when I see birds with only 3 or less colors they might be different colors than I have the options I have to pick from! I understand that there are limitations that make it difficult, but the app would be that closer to perfect if you added more colors and the option to pick more than three colors.
The other issue is that on a very slim chance I cant find the bird im looking for! This is for the most part my fault, but I think that sometimes it is because the bird isn’t on the list of birds registered on the app. It could also be because of the pictures of the birds do not include all or most variations of the bird I see, so I cannot confirm my sighting. If the roster of birds was filled up more, and there was more pictures, then all of those problems would be solved!
It is such a great app with such great features and it almost never fails me. The only issues it has are so minor, or could be fixed in an update soon, that it makes them nearly irrelevant. Because of all of this the app is virtually perfect, and i recommend all bird watchers newbies and veterans alike to download this app.
