Résumé :	This publication reports the current status of the Common Crane in Western Europe with regard to the colour-marking carried out from 1985 to 1998. After numerous markings with long alphanumeric rings, the currently used three-colour coding is presented as the best method for the identification of individual birds. The European Crane data base is established and some early results are discussed, including general remarks as well as specific information for several birds, which were sighted more than once, along their migratory route. To date, 301 Cranes have been ringed with the three-colour marking system. This has resulted in 253 observations of individual birds, whereas less than 10% of birds had previously been recognised using the alphanumeric system.
