Breeds in boreal coniferous forests throughout N Palaearctic (BirdLife International 2022). Belongs to redpoll complex with sister species: C. hornemanni and C. cabaret. Migratory strategies vary from resident to migratory and irruptive (Clement 2010).
Most recovery data from N and NW European ringing regions. Most populations follow on average a N-S or NW-SE axis, with recoveries as far as N Kazakhstan, up to China. Two recoveries at >4000 km, mostly <2000 km.
Overall, most recoveries due to ringing (92%). Pre-1960 recovery data show, however, ca. 30% of recoveries due to birds found dead, from them 5% by short, rest sound sick, wounded; ca. 60% of recoveries due to birds found alive (including recaptures associated to ringing). During the other two time periods, alive ringing recovery comprise 79% between 1961-1990 and 95% in the 1991- to present time period, with great increase in absolute capture numbers with time.
Annual Movements for Sizerin flammé
Post-breeding dispersal occurs from Jul to Aug. Autumn migration to S mostly from Oct to Nov. Number of migrants and distance travelled during migration strongly associated with food supply. Spring migration from mid-Mar to May (Clement 2010).
Connectivité par mois par région pour Sizerin flammé
Birds from UK move S/Se, reaching the S shores of English Channel, with recoveries in winter from S UK to W Europe (mainly France to Western Germany). Many recoveries in Belgium in Oct-Nov, showing then passage, rather than winter visitors. Probably, these birds follow a SE direction to SC Europe. Scandinavia birds move S, occupying most of N half of Europe in winter, with practically no recoveries in S Europe. Birds from E Scandinavia move SE, up to China; these recoveries in winter quarters mostly from Oct to Mar. Birds seemingly breeding in C Europe show more randomly-directed axes of migration, usually short-range or shorter than movements found from birds from N latitudes.
