Short abstract from the book: The bluethroat of the subspecies L. s. cyanecula is a very rare
breeding bird in Denmark, breeding in southwest Jutland.
Bluethroats of the subspecies L. s. s. are observed on migration
in May and August-September. In Denmark the first bluethroat was ringed in 1924; in total 1,298 birds have been
ringed, most in 1990 (121). Only one of the ringed birds has
been recovered: this bird (an L.s.s) was ringed on 17 May
1990 on Christiansø and died the following day after a window collision in Zealand 179 km west of the ringing site. Four
birds, also L. s. s., ringed on migration abroad have been
recovered in Denmark, three ringed in eastern Sweden and
one ringed in Norway. The foreign birds were recovered on
18 September, 13 May, 16 May and 17 May.
