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.
Amazing App for easy Bird ID
This app is wonderful! I knew next to nothing about birds until a Eastern Goldfinch landed in my bird bath one day spurring interest into exactly what the name of this beautiful bird was. I searched inline but characteristics I described didn’t help me find what I was looking for so I checked in the App Store for a bird identification app finding many games but only a couple of identification apps I downloaded 3 but found this to be the best for me. Since then I have become an avid bird watcher! The app is easy to use even for me. I was disabled by a drunk driver in 05’ & fed up with tv so great to find a hobby I can enjoy outdoors. Even my parents joined in & my daddy after suffering a head injury himself in 2011 took up the hobby along with wood working. Together we would make feeders & houses to help attract more birds. He would build & I would paint different types of houses I researched on the website to help attract birds of all types. Unfortunately We lost him to cancer in February of this year (2018) but the time we spent birding together these past 7 years is something I’ll always hold near & dear to my heart. Thanks so much to the Cornell Lab of Ornithology, Birds in the Hand, & the developers of the Merlin Bird ID for providing us with this wonderful app that has given me some very sweet memories & a wonderful hobby.
Best free birding app
This app got me started with birding. Last spring, I downloaded it to start identifying the common birds around me like American Robins, European Starlings, Common Grackles, and Northern Mockingbirds. Soon, I moved from merely identifying birds to counting them also, and soon after, I started recording full checklists with the EBird app (I think also a product of the Cornell School of Ornithology?), which is the best solution for those who wish this app would record their sightings. Now, less than a year later, I have 150 species on my list and have found a new lifelong hobby that I expect to bring me joy for decades to come. It’s all thanks to Merlin!
Though I eventually found that a high quality illustrated field guide (I use Sibleys in the US and Collins in Europe) is more useful than any app, I still reference Merlin for sounds or any time I don’t have my guide on me. I was very excited when Merlin came out with bird packs for Europe right before I traveled to Greece this past fall, and I look forward to seeing more bird packs coming out for other parts of the world as time goes on. It’s fun to scroll through the foreign packs and dream about traveling to new places and seeing those birds. I’d glad that when I do go, I’ll have Merlin with me to help identify them!
