Merlin Bird ID by Cornell Lab app reviews

  • Awesome 5/5

    By Lexigirl6
    Love this bird id app. Thank you Cornell!
  • Best birding app ever 5/5

    By Emilly22335
    Every birder, experienced or beginner, can use this app to help them in the field, I adore this app as it is very useful and helps me identify every bird I see. 100% recommended.
  • Fun! 5/5

    By Schincat
    I enjoy watching the birds at our feeder and then identifying them using this app.
  • Love this app 5/5

    By poeticdevice
    I have used other birding apps before- as I am certainly no birding expert. This app is so much easier to identify the right bird!
  • Excellent 5/5

    By Bike4birds
    I love the audio portion of the app because the sounds are more accurate than my other app, which I won’t name. And now I can search by name instead of taxonomic order. While my other app has more information, I find myself going to Merlin first. I’ve been birding for 48 years but I still find myself checking Merlin and I love to share the pictures and sounds with non-birders.
  • Amateur birders best friend! 4/5

    By Artfreak1
    Very useful app. I especially use the photos, maps and sounds to help identify hard to distinguish species. It's nice to be able to contribute to the science! We've identified several new species to our area. It would be helpful to have the ability to identify birds by nocturnal or diurnal choice. Sound I.D. Would be a great tool too!
  • So Educational and User Friendly 5/5

    Love this app. After moving halfway across the country, I’ve become obsessed with the different species of my new region. High quality app and information!
  • So much fun, such a great organization 5/5

    By Neuropus
    Update: AUDIO WAVEFORMS FOR BIRDSONGS NOW!!!!! I was a huge fan of this app before, but the waveforms are a game changer for learning birdsongs! Earlier: I learned about the app from their bird cam pages. This has been so much fun. Despite me being hardheaded "there's no way that's a woodpecker" (it was) I've finally got the learning tool to help me ID the fauna at our feeders. Quick, easy to use, fun, and you can contribute your sightings to their national data (or not).
  • Super Fast Identification 5/5

    By sooz_b
    So easy to use … as a amateur I find that I have a difficult time remembering details of the bird if I ink catch a glimpse. Merlin helps tremendously with this!
  • Identifying birds is educational 4/5

    By Awaiting our Lord
    This app is fun to use. We identified 2 birds so far. We love that the songs the birds sing is included. Looking forward to identifying more birds:))
  • Mystery bird 5/5

    By Qinzin
    I described my bird by answering the questions and the first bird listed was my bird! Eastern Phoebe!
  • Love this app 5/5

    By LittleLaguna
    This is a great app for both novice and experienced birders. Because it offers different packs based on geography (included in the app), you’re sure to be able to identify any bird you’re scouting. The inclusion of recorded calls and songs makes it even more fun to use. My only wish would be for some kind of enhancement that would allow users to save bird identifications. I’d even be willing to pay more for an add-on that records my confirmed sightings so that I could track them over time. Right now, when you’ve made an identification and click “This is my bird!” It appears that the data is sent to Cornell but not saved anywhere in the app.
  • Outstanding App 5/5

    By elliot.wozniak
    I love this app! The bird ID works great and it’s fun to browse all of the different species and hear their songs & calls. Great work!
  • Love this App! 5/5

    By Wetland Ecologist
    Great tool! Easy to use! Includes calls and bird song!
  • Photo ID of birds is more than amazing! 5/5

    By pshimmons
    This app gives me photo ID for birds that is simply amazing! See a bird, take a pic, then this app will tell you what bird it is! It’s like having your bird expert mom with you at all times!
  • Bird App 5/5

    By Mal6743
    Wonderful. I enjoy being able to ID all the birds in my backyard. Very informative and the recorded calls are cool. I’ve had birds respond to the recorded call. Just love it.
  • Excellent tool 5/5

    By E. Eddie Edwards
    Use it all the time to ID birds. Quick. Accurate. Fun. The songs are helpful too.
  • Merlin bird ID 5/5

    Great way to learn bird identification.
  • Middle TN bird watcher 5/5

    By in the 'Boro
    I love this app! It is spot on every time I’ve searched and tried to identify a bird. Now we’re trying to recognize their songs and chirps using Merlin. Thanks for such a great app!
  • Merlin app 4/5

    By Kathleen_kent
    I really enjoy the Merlin bird ID app! It’s easy to use and more helpful than going to a birding book most of the time. This app was very helpful when I went to Alaska and to Mexico since I knew hardly nothing of the birds in those areas. I like the bird call feature as well; those are fun to listen through so I can identify more of the birds in my area that are harder to spot. One thing I wish it did was save or catalog the birds I have identified. I think that could make the app more interactive and would be awesome for those who like scavenger hunts or to remember what birds they’ve seen recently.
  • A must have app for novice bird watchers 5/5

    By c00a5b70
    I'm not a bird watcher, but this app may change that. I was able to use this app to ID the first four birds I tried to look up. I've never had that kind of luck with a book. It's fun to actually be able to put a name to a face. In one case, I found out I was looking at a robin, which was funny because who doesn't know what a robin looks like? The thing is it was a juvenile and so didn't look at all familiar. Lesson learned. (Edit: A year later and I'm still loving this app. Latest ID — a lesser goldfinch)
  • My new favorite app 5/5

    By RobinLDM
    Looking up the bird you just saw in a book is not very handy. This app is great.
  • Very valuable ID app, even w/o cell reception! 5/5

    By Cavywavy
    I really appreciate this app! Particularly appreciate that when I know I’m about to lose reception, I’ll open the app to get GPS coordinates and then use that last georeference to key out birds I see. That’s pretty cool. And then of course the crowd sourcing data function, Love!
  • Birds! 5/5

    By BirdBoy4Life
    I love this app! Can’t get enough of my sweet sweet birds!
  • Love it! Wish it saved the birds you’ve logged 4/5

    By Missing background mode
    Just downloaded today and using it to identify birds with my kids. The algorithm is quick and appears to give accurate results. I do wish it had an option to view all the birds you have identified, but I can’t find that in the app interface.
  • Great resource 5/5

    By sccoolie
    My wife and I enjoy birdwatching and have found this app to be the best way to identify new birds to our feeder. Thank you
  • Grey app! 5/5

    By 
    This is one of the coolest apps available. I can easily identify any bird that comes to our feeder. Also great for hikes and walks in the park.
  • Merlin 🧙‍♂️ 5/5

    By Walkersmom777
    This app is awesome. Nuff said
  • Great app!! 5/5

    By MouseV
    The right bird is almost always at the top of the list!
  • We use this ALL the time 5/5

    By Bcolljames
    Even as experienced amateur birders we use Merlin all the time - especially to run through the likely birds in an area before we start birding
  • Makes getting into birding very easy 5/5

    By _eau
    Very informative and easy to use.
  • Good app 5/5

    By GB70Jonez
    Enjoy identifying the birds that come to our feeders and back yard area. Also like identifying their sounds!
  • A really good app! 5/5

    By Oregon Warrior
    The app does what it is supposed to do. I have had excellent luck identifying birds, both by describing birds, and by using the photo option.
  • Good start, but needs more 3/5

    By SandyO95
    Would do better to have additional characteristic choice like head or beak shape. I would love it if the app would keep your birds in a list and add to it as you see them. Also only gives basic info about bird, no nesting habits or mating facts. The photo feature is nice. Could be a really good app with some improvements.
  • Great App 5/5

    By R. Atkison
    Easy to use and very helpful in identifying birds. I use it often.
  • A full reference book in the palm of your hand 5/5

    By Slacker3172
    So easy to use .. I enjoy the photo identification aspect of this app and having the call and song audio is amazing. Worth every penny
  • The Best way to ID Birds. 5/5

    By DENLK
    Have been using app for 3 years. Very helpful in trying to ID a variety of birds across US. Doesn’t always work without WiFi as I need phone space so it gets stored to cloud.
  • Song recordings make ID easy 5/5

    By sorthund
    Walking in the woods, it’s hard to see some birds but the sound recordings make it much easier to recognize a bird or identify an unseen one by song. The explore function is very helpful too by giving a prediction of likely birds in the area- and the program is growing more accurate as more reports are generated by users. I do wish it were better on Alaska owls and raptors; so Alaskan birders, please send in your reports!
  • Merlin Birds 5/5

    By mophead2009
    Simple to use, accurate and I love the included bird calls and songs!
  • Really like it, but really wish you could save birds you’ve seen 4/5

    By ebiltz
    I really like the simplicity and effectiveness of the app. But, I Really wish you could save the birds you have ID’d, and revisit them later.
  • Love the App!!! ❤️ 5/5

    By BirdlovinLynn
    Easiest bird ID!
  • Great app 5/5

    By For a reward
    This app is great if you find a bird that you want to know what it is. The picture part of it works better then description part but overall it’s a great app. 👍
  • Great 5/5

    By DGFshark
    I love this app it is easy to use and my kids love making the bird calls
  • Great app but... 4/5

    By harpwhitt
    This is a great app to id birds but I wish it saved the birds I’ve identified and maybe the when, where, etc. info.
  • Great for ID, no way to track 5/5

    By Lulubug1018245
    This is overall a very user friendly app that allows you to see multiple pictures of each bird and even identify or confirm with their songs. The only negative I would say is it doesn't allow you to log a list of birds you have identified. That would be one recommendation. Overall a useful tool for beginner and intermediate levels.
  • Super useful! 5/5

    By glutten4gluten
    I use this all the time. I use it in town, on hikes, and in my yard. I love the accuracy of the photo ID and the sorting ID when I cannot get a photo (most of the time). I seriously love this app, especially because I’m not the biggest fan of having my phone with me, let alone on me at all times. It’s wonderfully useful.
  • Eastern kingbird 5/5

    By tdavek
    Bee trying to ident (guess) this bird on my fence and swooping down to lawn to pick up a bug and back up to the fence or swooping down to the lawn behind the fence and then landing on top of a tomato cage and then coming back to the near dog fence. Seemed more bluish black but in about a minute identified because of white tail tip and white underside. Great find. Can you incorporate a check off when birds are identified? Live in central coastal North Carolina and have seen many different birds at feeders and on fences and around the garden. Have seen Purple Martins putting on an air show above my back yard so am considering putting up Martin apartments or bar of gourds. Thanks
  • Great resource 5/5

    By papadoolittle
    My grandkids love learning about the many different birds and their songs and calls. I enjoy it more than they do. Nice!
  • Great resource for Bird ID 5/5

    By SuzieCute
    This is my go to resource for identifying unknown birds. It has never failed to ID an unknown bird and I highly recommend it to anyone curious about birds in their environment.
  • Can’t search for birds 2/5

    By AVkurt
    The app does not let you search. I think I have a screech owl, the I’d does not find an owl with the id. I want to see the screech owl listing and can’t. It’s ok for a novice who sees a bird. I want to find info on birds I don’t see. They have a huge data base but it’s worthless if I can’t search????
