Fantastic app, but still needs some work

I love this app, but I still require the internet and the General bird search to find my bird. For example I just put in a black and white bird and it came up with a galah, sulphur crested cockatoo, Australian king parrot and a rainbow bee-eater among other black and white birds. My bird wasn’t listed and I accidentally ID’ed the wrong bird. I ended up finding with the help of google and their bird list, but I can’t see any way of retracting my bird nor can I ID it through a general search. It has a lot of potential, it’s helping to keep an eye on bird populations.m and it’s free so I give it 5 stars.


A must have if it covers your area

This app is fantastic - with AI-driven bird identification from an uploaded image (even taking a photo of the camera or computer screen) and it is very accurate. There are 2 data packs for Australia, but only east coast so far.

The explore component is the equivalent of your field guide, but provides real world images uploaded by other users - which I find are usually more useful than the typical illustrations as it more often shows the differences seen across times of year, maturity etc.

Surprisingly accurate

I’ve been using Merlin for some weeks now and I am getting 100% accurate answers for common birds. That’s great and unexpected.
With rarer birds such as Glossy Black Cockatoo, these may not be in the database yet. Still, I am very impressed. I have used the Facebook group ABID much less since beginning to get accurate results from Merlin.
