••• About Photo ID •••
Powered by Visipedia, Merlin Photo ID uses computer vision and deep learning technology to identify birds in photos. Merlin learns to recognize bird species based on training sets of millions of photos from birders at eBird.org. When using Photo ID, enter the date and location where you took the photo; those clues improve Merlin’s accuracy by helping it focus on the species you most likely encountered there.

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.
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!
It has come to my attention that the algorithm used to show likely birds in a region is flawed. The algorithm occasionally causes rare birds to appear common at certain hotspots. My guess to how this happens is likely due to the birding community discovering a rare bird and sharing that info with their community. Then people from all over show up and enter the bird into eBird. This causes a large number of people to report the same single bird. As a result the algorithm will occasionally tell you birds like a scissor-tailed flycatcher is common at Arcadia Marsh, MI. When as far as I can tell it was only seen on one day by many people. Or it could tell you that a lazuli bunting or a painted bunting are common at Whitefish Point, MI when in fact there are very few historic reporting a of either of those birds statewide. An improvement could be made by changing the algorithm to factor in the number of birds reported per checklist for example (10 trumpeter swans) along with the number of days the bird has been seen over a period of time. This would prevent anomalous inaccurate results for a single bird that was seen up to hundreds of times on only 1 day. Aside from that the app is excellent at what it was made to do. As a predictive tool of what birds you may find in a given region, extra research is required to double check Merlin’s findings.
