Short abstract from the book: he curlew is a rather rare breeder in Denmark with an estimated population of 300 breeding pairs. The species is a fairly
common passage migrant from late June to November and in
March–May.
In Denmark the first curlew was ringed in 1935, with
most ringed in the 1950s. The majority of the recovered
birds were ringed on Amager, mainly in August. Six birds
were of Danish origin ringed as chicks. Three of these birds
were shot less than 50 km from the ringing site in their first
autumn, one was found in western France on 11 August and
one during winter, also in France. The passage migrants from
Finland (190), Sweden (47), Estonia (2) and Norway (2)
have been recovered in Denmark, the first in late July and
most in August. Some birds stop over in eastern Denmark
before they fly to the Danish Wadden Sea. From Denmark
the birds migrate SW. During winter birds have been recovered in Britain, France, Spain and Portugal. In Denmark
the spring migration is in March–April, but only a few birds
have been recovered during spring.
