Breeds in tundra birch forest across the N hemisphere. Part of redpoll complex with sister species: C. flammea and C. cabaret. Migratory strategies vary from resident (S part of breeding area) to migratory (N part of breeding area). Wintering distribution up to middle latitudes across N hemisphere (BirdLife International 2021).

Connectivité globale pour Sizerin blanchâtre

Few recoveries, hampering us to obtain firm patterns for the hornemanni redpoll, though molecular studies suggest weak support to consider it as a separate species within the redpoll complex (Marthinsen et al. 2008). Thus, we strongly recommend to pool recoveries from hornemanni and flammea together. Recoveries from hornemanni mainly from N Scandinavia, following on average a N-S axis. Two recoveries at >2000 km, rest <1000 km, mainly from S Scandinavia to C Europe (though notice the few amount of data) . Impossible to disentangle connectivity patters due to the low amount of data.

Contrôles par Condition for Sizerin blanchâtre

Overall, most recoveries due to ringing (96%). No data before 1960. During the 1961-1990 time period, 92% of recoveries due to ringing activities. From 1991 to present, 97% of recoveries are due to ringing.

Annual Movements for Sizerin blanchâtre

Movements to S Scandinavia from Aug to Oct. Outstanding recovery of an individual ringed in Sweden in Oct, then shot in N of Kazakhstan in Dec. Spring movements back to breeding quarters from Feb to Mar (Clement 2010).
