Seabirds linking Arctic and ocean
Throughout their annual cycle, migratory animals depend on widely separated areas for reproduction, fuelling migration, moulting and wintering. By migrating, animals link these areas. As conditions in one area can affect the behaviour or state of an individual in a next phase of the annual cycle, kn...

Throughout their annual cycle, migratory animals depend on widely separated areas for reproduction, fuelling migration, moulting and wintering. By migrating, animals link these areas. As conditions in one area can affect the behaviour or state of an individual in a next phase of the annual cycle, knowing the area use of migrants is important for understanding potential drivers of individual performance and population dynamics. For many species, however, basic information on their migration route, stopovers and wintering areas is lacking. Seabirds are well-represented among animals with the longest and most spectacular migrations. Only a few decades ago much of what was known about seabird migrations was based on land-based sightings or anecdotal at-sea observations, providing only a fragmentary and incomplete picture. Since the development and miniaturization of tracking devices, in particular light-based geolocators, details of seabird migrations are revealed at a fast pace. In this thesis, the migrations of a group of long-distance migratory seabirds breeding in Arctic tundra areas around the North-east Atlantic was studied: Red-necked Phalarope Phalaropus lobatus, Grey Phalarope P fulicarius, Long-tailed Skua Stercorarius longicaudus and Arctic Skua S parasiticus.
