Awesome app, but there is one big problem

Hi. First off, I'd like to say that I love this app. My most favorite part is the Explore tab, as I like to listen to all of the different bird sounds from around the world. But a few days ago, I noticed that something was different on the Explore Tab. The layout wasn't how I remembered it looking. There used to be two buttons at the top of the page when you opened the Explore Tab, called ID Info and Sounds. I really liked how the ID Info and the Sounds buttons were separated from each other. It is better to have things separated, as I know where to find them when I have buttons to click on and select. Now, the Explore Tab is just one big thing, and it is super hard for me to navigate without the buttons that were there before to help guide me through and around the page. Could you please change them back to the way that they were before? Since I am blind, I use VoiceOver to navigate around my iPad, and the Explore Tab is really hard to navigate now, without the ID Info and the sounds buttons at the top of the page where they used to be, like I remember. Basically, VoiceOver doesn't like the new Explore Tab update. I am very disappointed about this, and I hope that you will read this whole review. This doesn't just impact me as a blind individual. It may impact other blind people that use VoiceOver to navigate around Merlin as well. Please respond back when you get the chance. Thank you.

Loads of fun

Let me begin by stating I never use the original function of describing the bird I see. If I can see it that we’ll, chances are I can identify it without Merlin. The same goes with the photo ID feature—if I can get close enough and get a good enough look , I can ID the bird as well as Merlin can. I have tested out the photo ID, and I believe it would be a useful tool for beginners. Be aware that it’s not perfect: it has just as hard a time distinguishing between sharp-shinned and Cooper’s hawks as I do. Where the app really shines is in the sound ID. At first I was a little skeptical. One of the first times I used it it thought that one bird was both a common raven and an American crow. Same thing with some gulls. It thought there was both a California and Herring gull. I eventually found one I could call a California, the Herring gull never materialized. It also thought there was a tundra swan, but upon reviewing the recording, there was nothing there, and definitely no swan within my sight. The more I have used it, however, the more confident I become in its ID power. Generally, if Merlin disagrees with what I thought the sound was, I’ll try to track it down and find it. And more often than not, I find what Merlin told me was there. But the most fun I have had with this app was watching a northern mockingbird singing while Merlin picked out thirteen different bird songs that one mockingbird had learned and incorporated into its repertoire.

Great for a beginner like me

I love birds and want to learn more about them. I have been hesitant to join birdwatchers as I’ve heard via birder email lists the experienced birders can be impatient and critical of newbies and also make it hard for newbies to join any groups. It’s like breaking into a click. That said, I felt I needed to learn before I even got started so I tried Merlin ID. I have used all 3 tools and find each one useful. I’m most excited about the sound ID though. This app is not perfect and you should question a match that seems questionable, like if it gives you a “rare” match. Do some research by listening to the call options to see if the match is authentic. This app also doesn’t recognize every bird. But, when there isn’t a match just submit the recording to Merlin so they can further improve the app. It is constantly improving and can only do that if we all help out. One day, I heard a bird but couldn’t see it. The sound tool identified the bird so then I knew what to look for and sure enough, I was able to visually identify said bird! I was super excited and encouraged. I also enjoy reading about each bird, the various photos and learning the different calls and songs. I’ve begun to share this with my daughter and grandkids when we take walks. My grandson lights up when he is able to see photos of the birds he is hearing and he’s only 2.5. Fun for the whole family!
