In Finland, ringing of birds was initiated 100 years ago, in 1913. Since then, almost 10.4 million birds have been ringed with more than 1.1 million later encounters. The data hosted by the Finnish Ringing Centre have been used for conservation and research purposes. Among other things, ringing provides information on migration routes, wintering areas, causes of death and site fidelity of birds.
The aim of The Finnish Bird Ringing Atlas Volume 1is to thank and motivate voluntary ringers, give research ideas for scientists and provide authorities and members of the public with information of movements of birds. This first of the two volumes gives an introduction to the history of ringing, illustrates temporal changes in numbers of birds ringed and encountered and also briefly describes other marking techniques. Species-specific part of The Finnish Bird Ringing Atlas Volume 1includes theorders from Anseriformes to Charadriiformes (waterfowl, grouse, divers, grebes, herons, birds of prey, crakes, waders and skuas). The second volume includes the rest of species accounts and tells us,among other things, about scientific research conducted on the Finnish ringing data and about ringing at bird observatories.
