Short abstract from the book: The tufted duck is a rather common breeding bird in
Denmark, breeding in most of the country. It is also a very
common migrant. In Denmark the first tufted duck was ringed in 1925, with most ringed in the 1960s. The majority of
the ringed birds are passage migrants and winter visitors. The
few recoveries of birds from the Danish breeding population
show that some winter in Denmark and migrate to Britain,
while others migrate as far as Portugal. The passage migrants
and winter visitors come from a large area: from Iceland in
the northwest to the River Ob in Russia in the east. Most are
from Finland and Russia. The ducks arrive in greatest numbers in November. During winter 77 % have been recovered
in Denmark. Some continue their migration towards the SW.
Outside Denmark most are reported from Great Britain and
France. Young birds in their first winter travel further than
older birds. In spring most birds depart from Denmark in
March–April but some not until May.
The largest known cause of death for recovered tufted ducks
is hunting. Most birds were shot in Denmark (37) and Russia
(36). Eleven per cent of the birds recovered dead were reported
as drowned in fishing nets.
