Short abstract from the book: The skylark is a common breeding bird all over Denmark.
Migrants pass Denmark in September–November and
February–May.
The first skylark was ringed in Denmark in 1921, with the
majority ringed in the first half of the 1990s. The majority of
the recovered birds were ringed at coastal sites, with very few
ringed at inland locations.
The Danish skylark population is migratory. The first
birds are recovered south of Denmark in late October and the
mean position is south of Denmark in October–November.
The migration is directed SW, and during autumn birds are
recovered in the Netherlands, Belgium and France. One bird
was recovered in France in winter and eight in Denmark. The
birds recovered in Denmark were all ringed during migration
and were probably from populations further northeast.
Many skylarks return to Denmark in February but only a
few have been recovered during spring. The mean position is
in Denmark in March. During spring and summer skylarks
have been recovered at the same site as they were ringed in
earlier years.
The recoveries give only very limited information about the
origin of the passage migrants: two birds ringed in Finland
as chicks were recovered in Denmark on 5 October and 3
March, both in their first year of life.
