Gunther Zieger

Long distance migrant, granivorous passerine, breeding across the Palearctic from Iberia to western Mongolia, with no subspecific variations but numerous geographic song dialects across the range. Winters in Sahelian bushy savannas of sub-Saharan Africa, patchily from Senegambia to Ethiopia (Grémion et al. 2021).

Connectivité globale pour Bruant ortolan

Three main migration flyways connecting breeding populations to three know wintering regions. Migration divide from the Balkans to Belarus, separating populations using the western versus eastern flyways. Low ringing effort in central and eastern Europe, preventing informing precisely the central flyway. The Russian breeding populations migrate by the Middle East and Arabian Peninsula to reach the Ethiopian and Eritrean highlands. Fennoscandian, Polish and western European populations use the western flyway, wintering between northern Guinea and southern Mauritania (Selstam et al. 2015; Jiguet et al. 2019).

Contrôles par Condition for Bruant ortolan

Poaching of ortolan buntings in western Mediterranean countries (France, Italy, Spain) provided most of ring recoveries of harvested buntings before the 2000s. Poaching stopped in 2018 in France, and conditions of recoveries largely heterogeneous along time periods. Most live recovery from actively migrating individuals along the flyways. Large ringing effort on last Norwegian population provided most of the recoveries along the western flyway.  Recent migration connectivity unravelled by light loggers (Selstam et al. 2015; Jiguet et al. 2019).

Annual Movements for Bruant ortolan

Spring migration starts during the last decade of March / first decade of April. In the North, birds mostly resighted on breeding grounds in May, in active migration in April. In the South-West, breeders are back on territories second half of April. No ringing data to inform the movements of birds using the eastern flyway, but light loggers data indicate a return to breeding sites mainly during the first decade of May in European Russia (Jiguet et al. 2019). In autumn, departures from breeding grounds mainly during the second half of August in the North and the East. Arrivals on wintering grounds mainly during the first decade of October. Hence nearly 6 months spent on wintering grounds.

Connectivité par mois par région pour Bruant ortolan

Pattern known mainly from the western flyway, though tracking data suggest similar phenology along the eastern flyway. Along the western flyway, autumn migration starts mid-August and peaks during second decades of September in France. Desert crossing (Sahara, Arabia) occurs mid-April in spring, second half of September in autumn (Jiguet et al. 2019).
