Short abstract from the book: In Denmark the black-tailed godwit breeds in western Jutland,
in the Limfjord area and more scattered in eastern Denmark.
The population is estimated at 600–800 breeding pairs.
The first black-tailed godwit was ringed in 1910, with
most ringed in the 1930s. The recovered birds were all ringed
in May–June and are probably all Danish birds.
Black-tailed godwits leave Denmark in July–August; the
last was recovered in Denmark on 16 August. The migration is directed SSW to SW. During autumn Danish birds
have been recovered in southern France and Senegal. The
first ringed bird to be recovered in Senegal was found on 4
August. During winter birds have been found in Senegal
and southern Europe. The spring migration seems to be more
broad-fronted than the autumn migration, with recoveries
from Morocco in the west to Italy in the east. Black-tailed godwits return to their breeding sites in mid-March.
Only one bird was recovered in Denmark as a one-year-old,
which might indicate that many spend the first summer
further south.
