Résumé :	All the sources of records of the serin (Serinus serinus) in 16th century Europe are (re-)examined, both those already known and some that have been newly discovered. Interpretation of this more detailed information confirms the results which were published by Ernst Mayr in 1926 in his doctoral thesis: north of 48degreesN there were no free-living populations of Serinus serinus in the 16th century. All I I localities identified refer to captive birds or to specimens in the bird trade, the origins of which can be convincingly traced. However, free-living populations are recorded from Carinthia (Austria), Trentino (Italy), Ticino (Switzerland), Provence and Gascony (France). An occurrence in the Swiss Jura (Botzberg), and indications that it was present throughout the whole Tyrol and the Rhone Valley, suggest that the serin had already begun to expand its range, but was halted by colder periods of the Little Ice Age after 1585, only resuming a rapid expansion at the beginning of the 19th century. The zoogeographic situation suggests that the western and eastern parts of the Central European population have a separate history of immigration. Their possible heterogeneity and subsequent fusion urgently require a genetic investigation.
