Short abstract from the book: The bar-tailed godwit is a common passage migrant in
Denmark in July–September and March–May. The greatest
numbers are observed in the Wadden Sea. In Denmark the
first bar-tailed godwit was ringed in 1952, with the majority
ringed in the second half of the 1950s. One of the recovered
birds was ringed at Langeland and 22 on Amager in May,
August and September. The few recoveries from the breeding
area indicate that the passage migrants come from northern
Scandinavia and northern Russia. Passage migrants ringed on
Øland and in southern Norway have been found in Denmark
in August–September. From Denmark the migration is
directed SW, and during autumn and winter birds have
been recovered in the Netherlands and Britain. Furthermore,
bar-tailed godwits ringed in Britain in June–February have
been recovered in Denmark. In late April and early May
birds have been recovered in western France. The first bartailed godwits arrive in Denmark in March, the majority
in April–May. Birds ringed on 19 and 20 May 1956 were
recovered in Siberia on 29 and 22 May 1960.
