Suomen rengastusatlas I = The Finnish Bird Ringing Atlas Vol. I.

Hardcover. Condición: Fine. Text in English and Finnish. 549 pp. In Finland, ringing of birds was initiated 100 years ago. Since then, almost 10.4 million birds have been ringed with more han 1.1 million subsequent encounters. These data, hosted by the Finnish Ringing Centre, provide information on migration routes, wintering areas, causes of death and site fidelity of birds. The aim of The Finnish Ringing Atlas is to thank and motivate voluntary ringers, give research ideas for scientists and provide authorities and members of the public with unique information on 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 describes other marking techniques. The species accounts include the orders from Anseriformes to Charadriiformes (ending to Skuas). The Finnish Ringing Atlas has been funded by the Kone Foundation and the Ministry of Environment.
