Wintering area and migration routes for Ortolan Buntings Emberiza hortulana from Sweden determined with light-geologgers
Författare
Summary, in English
The decrease of Ortolan Bunting Emberiza hortulana in
Western Europe over the last five decades has caused serious
concern for the survival of this species in Sweden.
In order to find out the migration routes and wintering location,
we equipped several males with geologgers. Our
data show annual cycles of migrations routes, wintering
grounds and time schedules for seven re-trapped birds.
The wintering area in West Africa is savannah woodland
in a mountainous landscape in Mali and Guinea. The
migration routes follow more or less the great circle between
the breeding and wintering areas. Most birds were
likely to have passed the well-known Ortolan catching
area in les Landes south of Bordeaux in France during
autumn migration.
