Birds of three worlds: moult migration to high Arctic expands a boreal-temperate flyway to a third biome.

ABSTRACT:

Background

Knowledge on migration patterns and flyways is a key for understanding the dynamics of migratory populations and evolution of migratory behaviour. Bird migration is usually considered to be movements between breeding and wintering areas, while less attention has been paid to other long-distance movements such as moult migration.

Methods

We use high-resolution satellite-tracking data from 58 taiga bean geese Anser fabalis fabalis from the years 2019-2020, to study their moult migration during breeding season. We show the moulting sites, estimate the migratory connectivity between the breeding and the moulting sites, and estimate the utilization distributions during moult. We reveal migration routes and compare the length and timing of migration between moult migran
