Muscianese E., Martino G., Sgro P., Scebba S. and Sorrenti M. 2018. Timing of pre-nuptial migration of the Song Thrush Turdus philomelos in Calabria (southern Italy). Ring 40: 19-30.
The European Commission has established that pre-nuptial migration of the Song Thrush Turdus philomelos in Italy begins in the second decade (10-day period) of January. This three-year study was carried out at two localities in the Calabria region of southern Italy from 2012 to 2014, with 3-4 ringing sessions every decade from mid-January to the end of March. In total, 447 birds were captured. Based on catching dynamics and changes in fat load and body mass, we documented that the species’ northward migration took place in mainly March, with early movements in February. As no migratory activity was detected before the second decade of February, the dates of the hunting season in this area can be re-considered.
We studied the population trend and movements of the Song Thrush during the winter near the Tyrrhenian coast in the region of Latium, from 2012 to 2014, in order to establish the timing of spring migration.
During standardized mist-netting we captured and ringed 431 birds. The data collected indicate that the study area is mainly visited by wintering thrushes with significant year-toyear fluctuations in the number of birds.
Based on the information gathered during this study, confirmed by the results of other studies carried out in southern Italy and France, we assume that spring migration starts in Latium between the second and third decade of February.
