Warblr is an app that automatically recognises birds by their song. The way in which it works is simple – make a recording with your iPhone, and Warblr will identify the species of bird/s that can be found in that recording, providing you with images and descriptions to help you learn more about our feathered friends.

In using Warblr, you will be contributing to a citizen science project, and hopefully one day helping to protect endangered species. We will be making the recordings and the data collected on species identification freely available to be used for research and conservation.

Warblr can recognise over 220 species of British bird, and works particularly well for garden and woodland species. Our technology uses the latest techniques in machine learning, and is supported by Queen Mary University of London.

**Please note – if you’re having any issues using Warblr please just drop us a line to**

So Disappointing

I really wanted this app to work, but sadly I am one of the many it seems who merely gets a message repeatedly saying I have no internet connection, which is not correct. I waited a while to write this review because I had sent an email to the developers asking for help but, two weeks later, I have yet to receive a reply, so I’m not only disappointed that the app doesn’t work for me, but also disappointed with the developer’s customer service.

I have been using this app for about six months now and I found it very good for recognizing the birds that are in my garden are flying around the coast that I live on. As I am visually impaired and I’m unable to identify the birds by signs a way of recognizing the Birdsong and putting it on a screen for me is absolutely superb and has made a world of difference to my pleasure of the garden. It is only fail to work on two occasions which let’s face it is better than the record of my wife’s car

Good App

This does work (now servers have been sorted) & have been using it for over a week. It is most effective if there is one clear bird sound rather than multiple at once etc but still good for a novice.
Bit on the pricy side (eg not free) & has crashed a could of times but overall good to use when out and about.
