BirdRing-RUG is the extended version of BirdRing and is intended for bird observers that read colour rings and metal rings for scientific projects of the University of Groningen (RUG). BirdRing-RUG not only automatically stores Location, Date, Time and Ring Code but also allows you to enter species-specific data-fields that require more background knowledge (so far only for Black-tailed Godwit). BirdRing-RUG prevents common mistakes, such as letters or colours that are not used. You can email observations to yourself in Excel (csv) format.
For other species you can use the standard version of BirdRing.
