Short abstract from the book: The grasshopper warbler is a scarce breeding bird in Denmark
and a rare passage migrant. The birds arrive in April and
depart in September. In Denmark the first grasshopper warbler was ringed in 1928 and in total 1,024 have been ringed.
The greatest numbers were ringed in 1981 (60). Only one
of the ringed birds was recovered: a bird was ringed on 9
September 1991 in Skagen and recovered 2 km away on 18
May 1992. Two birds ringed abroad have been recovered in
Denmark: one ringed on Heligoland on 14 May and one
ringed at Falsterbo on 1 August.
