Birds of Conservation Concern 4: the Red List of Birds
Wintering Migratory Birds
Bird ringing is an essential element to the understanding of birds because the number of birds ringed generates information on the survival, productivity and movements of birds, helping us to understand why populations are changing.
Although, we have been bird surveying and ringing in Britain and Ireland for over 100 years, we are still discovering new facts about migration routes, breeding and wintering areas.
