Short abstract from the book:
The whooper swan is a new and very rare breeding bird in Denmark, with only a single pair breeding in the country since 2002. However, about 40,000 birds winter in Denmark, and of these 703 have been ringed. Ninety-three birds, ringed in southern Zealand and in the northeastern part of Jutland from November to March, have been recovered dead. In Denmark the first whooper swans arrive in October, but counts and recoveries show that some still arrive in December. The winter population is mainly from Russia and Finland. Birds later recovered in Russia were all ringed in eastern Denmark. Whooper swans from different populations in Finland segregate differently in Denmark (see next chapter). The spring migration begins in March, and by April the mean position is in the Baltic Sea. The fastest ringed bird was ringed in Denmark on 18 March 1952 and subsequently recovered 1,217 km away in Russia on 23 April 1952. The oldest whooper swan was recorded close to the ringing site at an age of 26 years, 6 months.
