Connectivité globale pour Gobemouche à collier

The overall direction of migration is southwards, south-eastwards for western populations. All populations migrate to a single wintering region centred on Zambia and adjacent countries, using a vertical eastern flyway covering the Middle East then restricting to a large band from Egypt to the winter region. No difference between age classes. Almost no ring recovery from the winter range. Two recoveries obtained in October and April in DR Congo and Angola are away form the known winter range.

Contrôles par Condition for Gobemouche à collier

Most old records are dead recoveries, with a shift towards nearly 90% or ringing casualties in the 1990s. Tracked adults do stop-over in Libya in autumn where very few ringing recoveries, due to low ringing and observation effort.

Annual Movements for Gobemouche à collier

Birds breeding in the North move southwards, birds breeding in Central Europe too, with a few unusual records in South-West Europe. No difference between age classes. Most active migrants are recorded in late August and early September in South and South-East Europe, with a few late individuals in October. Light logger data indicate a desert crossing by late August/early September for breeders of Czech Republic, mainly mid-late September for Swedish adults; mainly last decade of April in the spring (Adamik et al. 2016), with a final rapid bout to arrive on the breeding grounds (Briedis et al. 2018), with a effect of climate change on arrival date (Weidinger and Král 2007). Autumn stopover of all these gls-tracked birds mainly from North Libya.

Connectivité par mois par région pour Gobemouche à collier

First migrants arrive in southern Europe during the second decade of April, and most breeders are on territories by the first decade of May in Central Europe, the second decade in the North. Autumn departures are concentrated in August, starting during the second decade, with few late individuals in September.
