Welcome to Ringers’ DigiGuide! This web site contains a photographically illustrated guide, meant to facilitate bird ringers in ageing and sexing birds (primarily passerines) of the Scandinavian countries.
Completing the guide is an ongoing project, and new species will be added in due time. Any suggestions of corrections should be sent to firstname.lastname@example.org. For public discussions concerning this guide, ageing and sexing of birds and other related topics, we recommend using the facebook group with the same name – Ringers’ DigiGuide.
