Short abstract from the book: The shoveler is rather rare breeding bird in Denmark, but
a common passage migrant in August–September and April.
The first shoveler was ringed in Denmark in 1920 by H.C.C.
Mortensen, and since that time most have been ringed in duck
decoys, mainly in the 1960s and ’70s. The recoveries show
that many passage migrants come from Sweden, Finland, the
Baltic countries and not least from Russia. The first arrive
in August, and by mid-August some are already recovered
SW of Denmark in Germany and France. In September the
mean position is south of Denmark, with many recoveries
from England and central France. Some reach Spain and
Morocco in October. During winter most birds are reported
from southern England and Ireland in the north to Morocco
and Senegal in the south. During winter most shovelers are
reported from Great Britain, the Netherlands, France and
Spain. The shovelers migrating to Africa tend to use a southwestern route across the Iberian Peninsula. The spring migration seems to take place rather quickly, and recoveries from
northern Italy in February and March indicate that some
cross central Europe. The greatest proportion of the recovered
birds have been shot.
