Short abstract from the book: The cuckoo is a common breeding bird all over Denmark. The
birds arrive in early May and most have departed by the end
of September. The first cuckoo was ringed in Denmark in
1919, with the highest numbers ringed in the late 1950s. Only
26 birds have been recovered, the majority of these ringed as
adults. We have only very limited information on the migration route and winter quarters of the Danish birds, since all
recoveries from autumn are from Denmark and no birds have
been recovered during winter. In spring two birds have been
recovered in Italy (30 April and 11 May) and 18 birds have
been recovered in Denmark (all after 15 May). Twenty-eight
cuckoos have been recovered less than 50 km from the ringing
site (25 in a subsequent year). The mean distance between
ringing and recovery site of seven birds ringed and recovered
in June-July was 6 km.
