Merlin Bird ID by Cornell Lab Reviews

Fantastic app BUT (12/30/24)

CellularDoor80 on

United States

I have been enjoying this beautiful app, and it is one of the most comforting things ha in my life. For two days in a row, however, my app (when recording birds, manually) the recording shows a blue light, saying “hearing a bird” and I am hearing cardinals, and mocking birds, as well as crows… it shows it is “hearing them” but offers no identification. Located at 38401. 35* 36’ 12.5” N 87* 48.1” W. Thanks. I will reinstall and possibly lose my recordings.

Okay

This app doesn’t know quite a bit of sounds and also didn’t notice the difference between a black-capped chickadee sound and a Carolina chickadee sound from the book “The backyard birdsong guide” which also had a label by TheCornellLab of Ornithology

☹️

Great for Bird watching

This app is really accurate when hearing birds. I just started bird watching and it is really fun using the app and well made.

Just record please

al savory on

United States

The app is getting carried away with all these pop ups that prevent me from recording right away. Very frustrating to deal with in an app that should be straightforward and not in the way when its already hard enough for the mic to pick up the call/song. Please stop putting pop up things like "my picks" and other random notifications.

App Needs Better Editing

stash on

United States

I really enjoy using this app when I encounter a bird I’m unfamiliar with and listening to their calls. I have been using this app for many years and have recently encountered an issue with editing past bird sightings. I am finding it’s impossible to edit notes I write on a sighting. So now, every new sighting repeats the notes of a previous sighting and I can find no way of deleting it. Very frustrating.

Sound ID is incredible

RT Arrow on

United States

On the rare occasion that sound id doesn’t work, you can easily confirm by listening to the samples that pop up. And btw…. that’s only happened two or three times of the dozens of sound IDs I’ve done, all in windy/noisy conditions. Truly impressive application of sound recognition and also the corpus of sounds that people have collected.

Absolutely one of my very best apps!

tam rya on

United States

I only use the ID by sound, because it’s awesome to hear a bird and have Merlin listen. Not only does this app make it simple and enjoyable to identify and record birds, but it also pairs very well with eBird, to easily report for data and research. And, this app just plain works flawlessly. I’m not normally impressed with app performance, but this one stands out far above just about any other app. Not flashy and glitchy, not shoving ads in your face, just perfect. This is easily used by casual users, but very satisfying for dedicated birders.

Love the app but wish it didn’t update

United States

Individual life list numbers # disappeared with the newest update which is a shame. Please bring it back! I want to know what my 100th vs 200th bird is. Not just my overall total.

One of my top 5 favorite apps ever!!

Treybcool on

United States

This app is incredible! Whether in the city or the woods, I am breaking this app out and identifying the birds around me. The app has made me more aware of the amazing world around me. Thank you Cornell!!
