Bulgarian Bird Ringing Scheme is run by the Bulgarian Ornithological Centre (BOC), which (1) coordinates the use of bird ringing as a scientific method in all studies on wild birds in the country; (2) conducts research focused on migration, biology, ecology, behaviour, monitoring and conservation of birds; (3) trains people in bird ringing and promotes bird-related scientific knowledge among the general public; (4) provides expertise in the field of ornithology to governmental bodies, non-governmental and other organizations.

BeBirds, the Belgian Ringing Centre, is hosted at the Directorate Natural Environment (OD Nature) of the Royal Belgian Institute of Natural Sciences, one of the 10 scientific institutions of the Belgian Federal Science Policy Office (BELSPO).

Scientific ringing of birds was invented by H.C.C. Mortensen from Viborg in Denmark. Beginning in 1899 with the ringing of 165 starlings with unique identification numbers and an address, the method quickly spread to other countries all over the world. Seven ringing schemes have operated in Denmark. The scheme at the Natural History Museum of Denmark, University of Copenhagen (DKC), is the largest with more than 4 million birds ringed and around 200,000 recovered.

The Albanian Ornithological Society has been actively undertaking Bird Ringing activities and research since 2016. Since that time we have marked 11,438 individuals of 87 bird species with uniquely numbered aluminium rings. The importance of this amount of birds being ringed using this method is shown by the fact that during our work we were able to confirm the occurrence of two species new to the avifauna of Albania. We have undertaken more than 15 bird ringing camps along the costline of Albania.

Bird ringing in Britain & Ireland is organised and run by the British Trust for Ornithology (BTO). Bird ringing began in Britain in 1909, originally as two separate schemes, one organised by Arthur Landsborough Thomson at Aberdeen University and the other by Harry Forbes Witherby, the then editor of the journal British Birds. The Aberdeen Scheme ended during WW1 and the British Birds scheme was transferred to the BTO following their founding in the 1930s. The number of birds ringed in 1909 was just 2,171.
