Résumé :	Crane numbers using the various European flyways are reviewed. Colour marking of Common Cranes led to new findings thanks to high resighting rates. The western European route is mostly used by Scandinavian, German, Polish and north-eastern European populations, the Baltic-Hungarian route mainly by Finish, Baltic, Belorussian and Russian Cranes. The former flyway is at present used by more than 100,000 birds, the latter by approx. 80,000. Birds of both routes come together and mix to a certain extent in eastern Poland and the Baltic countries. Here, parts of the populations seem to mingle, and major portions of the Baltic and Finnish populations turn westward, whereas small contingents of the Scandinavian cranes fly south-eastward. Particularly interesting is the fact that Finish cranes that were registered both in central/western Europe and Hungary, may switch between flyways from one year to the next; there seems to be no relation between the geographic origin of the birds in Finland and the route they chose. Crane numbers counted at central European and Hungarian staging sites, where more than
