Great app

I've only been using the app now for a week and find it very accurate. There are several birds that don't show up on the list but overall it is a great app. I like the option of going to the bird calls so you know what your listening for. I've hesitated using the call while birding but have been very tempted to help bring the rails out of the brush so I can get a picture of them.
If they could add others like the Rose Breasted Becard and MacGillivarys warbler would be nice but it's also nice to have a free app with all these features for free.
Was able to download the Central America bird pack and found the two above mentioned birds.
Just a great app to have on your phone while Birding yo help with your identification of the bird your looking at.

Love it so much

I use this app nearly every day. I'd love a feature for users to review a list of birds (w/ dates and locations) that they've identified. But, that's just a suggestion for an already awesome app! I've tried a couple of nature id apps and none of them are even close to the accuracy of this one. I also love the "explore" option - to view which birds you're likely to see that day in your specific location. Thanks for creating this wonderful app!!!!


What a great app!! You see a bird and you think " hmm I have never seen that one before I wonder what it is"? You go to the Merlin app fill out a couple of screens and PRESTO MAGIC you find your bird!! You can also listen to its calls!!! Even if you are not in an area to use it you can change locations when you get in area to use it!!! I just love this app!!! What a great way to introduce kids to birding!!! I tell everyone I can about it!!
