Short abstract from the book: The great grey shrike is a rare breeding bird in Denmark with
an estimated population of 30 pairs, all breeding in western
Jutland. It is a rare winter visitor. In Denmark the first great
grey shrike was ringed in 1930, with the largest numbers
ringed in 1966 (39) and 1967 (39). One of the recovered
birds was ringed as a chick but the rest were probably passage
migrants. Nine birds ringed abroad have been recovered in
Denmark. The recoveries of foreign birds indicate that some
of the winter visitors come from Finland. These birds were all
ringed in late September and October and two were recovered
in Denmark within 11 days of ringing. These Baltic birds
were all recovered in eastern Denmark. Three birds ringed on
Amager in September–October were recovered in Germany
and the Netherlands later in the winter, showing that some
birds continue SW. Other birds have been recovered or ringed during winter in Belgium, France and England. Others
remain in Denmark throughout the winter. Six birds ringed
in October–December were recovered close to the ringing site
later in the same winter, and one was ringed on Christiansø
in October and recovered in west Zealand in December. The
only bird that was ringed as a chick was recovered in central
Jutland during winter. Birds ringed in England and Belgium
have been recovered in Denmark in the second half of April.
