ResumoRedwing Turdus iliacus migration in Italy has been investigated on the basis of ringing recoveries stored at the Italian Ringing Scheme. A total of 718 foreign recoveries and 936 recoveries of birds ringed in Italy have been analysed. Most Redwings migrating through, and wintering in, Italy come from the Baltic area. The first thrushes on post‐nuptial movements arrive in September, though the bulk of movements starts in the second week of October, peaking in mid‐November and ending in late November, while Italy seems not to be influenced by strong return movements. In regions of northern Italy like Lombardia very few birds stay after December, while good numbers of wintering Redwings are reported from areas with a milder climate like Toscana. The previously reported low fidelity to the wintering grounds is confirmed by our analysis, suggesting the use of two distinct areas in subsequent years; the potential influence on the selection of wintering quarters of local conditions upon departure for the Baltic crossing is discussed.
