About this app

An app to help bird ringers, nest recorders and scientists check the correct ring sizes/codes to use for each bird species ringed in the UK (for both full-grown birds and pulli) and the codes needed to record nests and their contents. The app also includes the codes needed to record biometrics, condition and status information for each bird as well as the standard habitat codes.

This is a very useful app. I don't seem to be able to search for a species though as there's no menu button....

What's new

The app has been updated with an improved look and feel, and now contains the latest species data and additional resources for both ringers and nest recorders. When launching for the first time, you will need an internet connection. Once the required data has been downloaded, the app will continue to work fully offline.
