Résumé :

An attempt is made to understand the reasons for the current expansion of the Redpoll by comparing the earliest historical records, here those on winter invasions in Central Europe. Their number increased from the middle of the 16th century onwards, parallel to the supposed development of the Maunder minimum of the Little Ice Age. Redpoll invasions have been reported by several independent sources, indicating that the density of historical records is sufficient to reconstruct correlations between climate and oscillations of bird ranges, even in the case of a relatively inconspicuous, frequently confused small Fringillid.
