Short abstract from the book:
The common gull is a familiar breeding bird in Denmark, breeding in colonies on small islands and on the coast. It is also a common passage migrant and winter visitor from August to March. The first common gull was ringed in Denmark in 1910, with great numbers ringed since the 1920s. Fifty-five per cent of the recovered birds were ringed on Zealand, 26 % in Jutland, 9 % on Funen and 4 % on Lolland-Falster. A large proportion of the recovered birds belong to the Danish population but many winter visitors have also been ringed and recovered. Most of the Danish common gulls are migrants. The first young birds are recovered abroad in late July, and in August more have been recovered in Germany, the Netherlands and Britain. In September, 27 % of the young birds have been recovered from abroad. The birds migrate along the German and Dutch coastline to the English Channel, and some further south to the Bay of Biscay. During winter 14 % of the Danish common gulls have been found in Denmark. Abroad most have been recovered in France and the British Isles but also in the Netherlands, Belgium and northern Germany. The mean position in winter is further west for birds ringed in Jutland than for those ringed in eastern Denmark. Furthermore, in general young birds in their first winter have been found further south than older birds. Most of the mature common gulls have returned to Denmark by the end of April, whereas the return of immature birds seems to de delayed and many do not return until maturity. Migrants from populations around the Baltic Sea and northern Russia arrive in Denmark from August. Many Swedish and Norwegian common gulls migrate further south to winter in northern Germany, the Netherlands and southern England, but the number of Finnish and Russian birds remains high throughout the winter. Most migrants depart in March. The main known cause of death is hunting. Seventy-three per cent have been shot in Denmark, mainly between August and September. The proportion reported as shot has declined since the 1960s.
