Short abstract from the book: The rough-legged buzzard is a common passage migrant
and winter visitor in Denmark from October to April. In
Denmark the first rough-legged buzzard was ringed in 1953,
with most ringed from 1960 to the mid-1980s. The majority of the recovered birds were ringed in traps from December
to March. Only one of the recovered birds was ringed in
Jutland.
Recoveries of rough-legged buzzards ringed or recovered in
Denmark show that the winter visitors come from Norway,
Sweden, Finland and Russia. Many of the birds return to the
same wintering site year after year: all nine birds that were
ringed and recovered in Denmark in subsequent winters were
found less than 10 km from the ringing site. However, two
birds ringed in Denmark during winter were recovered in the
Czech Republic the following winter. Most rough-legged buzzards depart from Denmark in April, but five one-year-old
birds have been found in Denmark in May–July.
