Prolonged stopover duration characterises migration strategy and constraints of a long-distance migrant songbird
Stopover behaviour is a central element of migration strategies. But in recent geolocator studies, despite now being able to track individual songbirds during their entire migration, their stopover behaviour has received little attention. We used light-sensitive geolocators to identify the migratory...

Stopover behaviour is a central element of
migration strategies. But in recent geolocator studies,
despite now being able to track individual songbirds
during their entire migration, their stopover behaviour
has received little attention. We used light-sensitive
geolocators to identify the migratory routes and schedules
of 12 northern wheatears (Oenanthe oenanthe) breeding
in Sweden. Three geolocators collected temperature data
complementing inferences from light data by providing
additional information on behaviour during migration.
The wheatears performed a slow migration with
considerable stopover time (84%/76% of autumn/spring
migration), with short stops while traveling through
Europe, and a prolonged stopover period in both autumn
and spring in the Mediterranean region. Spring migration
was faster than autumn migration, mainly because of
decreased stopover time. Migration routes and time
schedules were similar to those from a German breeding
population. Compared to wheatears breeding in Alaska
with a three-fold migration distance, Swedish wheatears
spent more time during stopovers during autumn and
spring migration, suggesting less time constraints and
potential flexibility in migration schedules. The finding
of prolonged stopovers, similar to other recent geolocator
studies, shows that temporary residency periods may
be common. This changes our current view on stopover
ecology to one where temporary residency periods are
part of spatio-temporal strategies optimising resource use
during the entire annual cycle. |
