Since some time there is a new app for mobile phone that is able to enter observations of colour rings of geese and swans (and other species of birds) while in the field.

The Bird Ring app is downloadable to your (Android) phone via Google Play Store or see After entering the data of the colour ringed bird in the field a push at the button  uploads the observation to or to

We hope this Bird Ring app will give more pleasure to reading colour rings.
