    Wonderful app makes identifying birds easy!
  • Great way to identify birds and learn more about them! 5/5

    By PaulThePhotographer
    Quick and easy to use. Seems very accurate. Then provides all sorts of extra information about your bird. Best Bird Identifying App! IMHO
  • Bird watching 5/5

    By Barbara Meyer Ring
    Love this application. Makes it easy to find and to know all about the birds. I am thankful for this app. I get so many different birds coming each day. And I’m not that smart about computers and electronic devices, but this makes so easy. Thanks
  • Pictures sometimes don’t show up for specific birds. 5/5

    By Wingnut1438
    Absolutely love this app! I have been using it since winter, but recently, a bunch of the pictures for some bird species, like the indigo bunting, have disappeared, and just show the image of the app’s symbol in gray and white. Please fix this soon, because it has made the app harder to use.
  • Love this app! 5/5

    By nowandthen reviewer
    My 4-year-old and I have fun spotting and identifying new birds with this app, and she especially loves playing the audio snippets of their sounds. Nice to have handy on the phone. Easier to get an ID than with Google.
  • Very useful 5/5

    By ret_teach
    Great addition to a birding guide. Paired with a good guide speeds up the process.
  • Merlin Bird ID 5/5

    By MarggH
    Love it! This is by far my favorite app. I’ve recommended it to almost everyone I know. I have identified a lot of birds very quickly that would have taken quite a while looking through a guide. It also introduced me to Cornell Lab. I have taken part in Birdfeeder Watch for 2 years.
  • Great bird ID app 5/5

    By e-step-to-my-lou
    Can’t wait until they use sounds, too. And flight patterns. Love this app!
  • Bird ID 5/5

    By jeaniep az
    I love it. It really works.
  • Great birding app 5/5

    By 12AMMKV
    Great, easy to use app. My four year old can use it as well. Start them young.
  • Simple, intuitive bird identification tool 5/5

    By Perry Quatro
    I recently put up a bird feeder and was surprised by the number of different birds that visited my feeder... and also by how little I knew about the birds in my area. After trying other apps and online sites to ID the birds, I’ve found this app to be the simplest, most intuitive and highest quality source for bird identification. I especially like the feature that shows me the birds I’m likely to see based on location and date, and I enjoy being able to contribute to the accuracy of the database through bird sighting submissions. I only wish that I could have access to the record of my bird sightings, since my limited knowledge of these birds means it’s likely that I’ll forget over time which birds I’ve sighted. Overall, though, I give this well-designed app two thumbs up and five stars!
  • Great tool 5/5

    By Annie & Tom
    We have been interested in bird watching for years, but feel we have been learning very slowly. We have only recently started to use Merlin, but have already found it to be helping us identify birds much quicker and with more certainty.
  • Great app 5/5

    By Lolasb
    Love the fact that they have the birds song as well.
  • Excellent app for beginners 5/5

    By LonScof
    I enjoy using the guides choices to ID the bird I’m seeing, but I LOVE the capability to choose a grainy photo I took of the bird and have the app ID it for me! Sweet.
  • Great resource! 5/5

    By _cfd_
    Easy to use and I’ve almost always found my bird. I’m reaching for it all the time, especially when traveling and recommend it even more often! I love that it has clips of songs and calls too. Keep up the good work, CLoO!
  • Great App 5/5

    By PureJadeKid
    The filter feature combines eBird with the ID app which is very useful. We love it. Great to see bar charts for each species so you know when to look for birds in a given location.
  • It’s fun 5/5

    By Barb Booleybooley
    What else can you say. It is so fun to watch the birds come and interact with this.
  • Great app 5/5

    By gminard
    This app is excellent! They constantly update it & the bird libraries are extensive. Their bird ID section, which works by asking s few simple questions, works really well. Very intuitive app, also.
  • Great bird ID 5/5

    By Lurlean
    I LOVE this app! Really simple and easy to use. It makes me so happy to know the kinds of birds wherever I am. One of my favorite features is that you can listen to their songs and calls, also, and there are multiple pictures of each bird. LOVE!!!
  • Joy 5/5

    By Solo1wolf
    Pure joy using this app as we watch the different birds in our yard and on the feeder. Highly recommend this app for the entire family 🦅🦆🐥 Bill
  • Brilliant App 5/5

    By Philiposan
    Brilliant Application that is useful to all bird lovers, watchers, and those interested in conservation. I am constantly recognizing new species, many of which I always presumed were just individual variants of species I had previously identified. Thank you Cornell Bird Laboratory.
  • i love this thing 5/5

    By eflask
    it helps me study birds i don’t remember, learn birds i never knew, and most recently i fired it up for a group of people who had never heard of a veery. it’s an excellent tool.
  • Great app 5/5

    By Soggy Cyclist
    Excellent resource. Easy to use.
  • Great teaching tool for kids! 5/5

    By Samme Le
    Love the app! Wish I had more space on my iPhone for more regions. Also would love to see it downloadable for the surface tablet.
  • Bird journal in your pocket 5/5

    By brokefrommusicstore
    Great identifier with your phone. You don’t need a good photo to make an ID. The app lets you crop quite a bit. Songs and calls are top notch and range maps very good. Highly recommend.
  • I never thought I would birdwatch! 5/5

    By Liseny
    Always had an interest in birds, but new I would never spend the time memorizing all the songs due to time constraints. This app has enabled me to identify and enjoy birdwatching and join bird counts, easing that time investment and allowing me to contribute to scientific migration studies! The app itself gets better every day and is able to accurately identify the birds I try to identify on the first shot. Highly recommend you download the bird packs in case you lose your data connection, you can keep using!
  • My kids love it! 5/5

    By Mtn.Mommy
    After doing a thorough study of birds in my son‘s second grade class, we downloaded this app and use it regularly. I love being able to discover new birds with him! It is such a user friendly app and we have found it to be extremely accurate. Highly recommended and a great way to explore God’s creation with your children.
  • JK488 5/5

    By JK488
    I love to photograph birds of all types and sizes but have never learned their identities so this app is absolutely wonderful for me. It is so easy to input a few specifics and have pictures of the possible candidates appear. The accuracy of this app is excellent and just what I needed.
  • Easy to use! 4/5

    By BJ Watcher
    I have been feeding and watching birds for a number of years. However I still consider myself an amateur birder. Over the years I have tried different bird identification apps with a small amount of success. This app is very easy to use, quick and accurate.
  • Wonderful 5/5

    By Is it possible?
    Maps, regions, sounds & calls all great!
  • A pleasure to use! 5/5

    By birding novice
    This made it possible for me to quickly identify birds that I normally don’t see in my city. It was a real treat to have definitive answers to grandkids’ questions about the birds we saw.
  • Handy and insightful 3/5

    By Crunchnoodles
    I find it informative, and convenient, from r the most part...
  • Bird songs are clutch 5/5

    By birding DJ
    Spent two days in the Cuyahoga Valley National Park and identified 10 new birds with the help of the song recordings. Keep up the great work. This app also allows me not to carry three books in my backpack!! Easier on the back.
  • Couldn’t download, garbage app 1/5

    By emc2093
    Bird pack downloaded and was seconds from finishing installing and the app crashed. Reopened the app to see the download and install were deleted/cancelled. Terrible app
  • Great app! 5/5

    By revneb
    This helps a lot with bird ID. Good info. & pictures.
  • Truly outstanding app 5/5

    By Maia30
    We seriously love this app. We have been watching birds for years and are thrilled when we see something new and can report it to Merlin/Cornell. Not only can we ID visual characteristics, we learn more about birds’ behaviors, diets, and can listen to their songs and calls so that we know they are near even when we can’t see them. Recently, I tried to report a bald eagle sighting, but Merlin didn’t recognize it for my area. I reported no matches, and a week or two later, bald eagles were available as a selection in my area. Possibly someone used the photo ID to submit a picture as proof, which is an excellent capability. This app is a lot of fun and very educational. Thank you, Cornell!
  • Wonderful app for birding 5/5

    By bcbengt
    Great app for identifying birds and learning more about them.
  • Good 4/5

    By Blazed52
    Good ID and songs , would be a 5 if we could save a list of birds personally ID’d
  • Merlin Bird ID 5/5

    By Ron47
    This is just amazing. Its results really narrows the choices and with further review you can identify a bird easily. I am not expert at identification but this program has made it a lot easier to identify birds. Easy to use. You can also submit photos for identification and really makes it quick to identify various bird. A very good program for all birders!
  • Great program, but wish . . . 4/5

    By Foolmother
    This is really a great program. It shows all the phases of the birds which are always different in different seasons or ages. I have identified the bird calls because of the inclusion of the sounds. One teeny, weeny wish would be that the program kept a log of what you have seen, maybe including date and place. They have that info, so it doesn’t seem too hard to include it. Then it would be a perfect program.
  • Fantastic 5/5

    By binoculors
    Incredibly great app! And gets better and better with new updates. Hope to see all the birds of this planet being added with time. Congratulations to all the people who worked and still work on the app.
  • Love This App!!! 5/5

    By aag0702
    This app is to birds what IMDb is to film. If you love birds and you love looking things up and using searchable databases, you will truly enjoy this amazing app. I use it several times a week and it is my absolute first place to look when I’m wanting to find out anything about birds where I live and where I hike and kayak. This app provides accurate and quick information in a fun way! It’s so much easier than turning pages in a bird book or searching the web. I will never take this off my smartphone because I never know when I’m going to need it!
  • Amazing 5/5

    By Nicknackhackmack
    Thoroughly amazing and useful app, I would love it even better if they added a Hawaiian Islands bird pack
  • ID Mystery Birds 5/5

    By Alice's Morsa
    With this app, I have been able to identify a painted bunting pair (male and female) and a couple of male Carolina Chickadees. It’s a lot easier to enjoy your feeders when you know which birds are visiting you.
  • Love it 5/5

    By cseguin655
    Love this app! Always find my bird I’m trying to identify easily. Makes bird watching more enjoyable finding birds and their songs.
  • It would be better if I can save the history 5/5

    It would be better if I can save the history
  • Merlin! 5/5

    By Bjohnjr
    iPhone 4S. Easy to use, and unlike many apps is still working with my old phone (iOS 9.3.5). Great features and just the right amount of information for on the go birdwatchers, or anyone who is curious and says "I wonder what bird that is?" John
  • Merlin review 4/5

    By lijomar
    I am continuously amazed by the accuracy of the bird ID based on the simple questions and location! I am very careful not to use the calls on a way that might alarm the birds, but I do enjoy listening to them. I do wish there was a feature to put in a particular bird name and receive the info on that bird. Maybe there is and I don’t know?
  • Bird ifentigication 5/5

    By Date keeper
    Great. Love it.
  • Love this App! 5/5

    By Wetland Ecologist
    Great tool! Easy to use! Includes calls and bird song!
