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**

Very Disappointing App that was advertised on the gadget show

The app recorded sounds for 30 secs and produced a readout of percentage of birds it could recognise but what would have been nice in the identification, is a button to play each individual sound (as on one I found with the blackbird). This would then actually help the identification by sound, which is why I paid for the app. I feel I have been ripped off. I could have gone to wiki for free to get this information.

So Disappointing (but see added update below)

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.

UPDATE: I have since been contacted by the developer’s support team with profuse apologies. They had a server problem, which is now fixed and my app works, although I haven’t yet tried it out.

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
