Short abstract from the book: The red-backed shrike is a fairly common breeding bird and
passage migrant in Denmark. The breeders arrive in the first
half of May and depart in August-September. Migrants pass
in May-June and in August-September. In Denmark the first red-backed shrike was ringed in 1922, with the highest
number ringed in 1976 (709). Half of the recovered birds
were ringed on Christiansø and only eight were ringed west
of the Great Belt. The ringed birds are mainly of Danish and
Swedish origin. South of Denmark, the first bird was recovered in Dresden in Germany on 25 August; in September
birds have been recovered in Greece and Egypt. One bird was
recovered in northern Italy in November. The fastest bird was
ringed on Christiansø on 20 August and recovered in Greece
20 days later. Four birds ringed on Christiansø migrated in
unexpected directions, to Falsterbo, Blekinge and Öland. One
bird was recovered in the presumed winter quarters in central
Africa during winter, in DR Congo on 1 December. A few
other birds were recovered south of the Sahara in April and
May/June, indicating a late spring migration. The first bird
was recovered in Denmark on 7 May. Forty-two per cent of
the recovered birds were recorded by ringers. Of 38 dead birds,
most had been hunted, collided with vehicles or killed by cats.
