The ringing program of Whooper Swans runs in Lithuania and Latvia since 2008. Juveniles, breeders and moulting swans are caught and ringed in summer, but also few birds are ringed during migration and wintering. Until now c.300 Whooper Swans have been ringed in Lithuania with blue neck collars with white codes: 7C00-7C99, 2H00-2H99, 3H00-3H99, 4H00-4H99.
The first birds started to breed in Lithuania 25 years ago and at present we have 80-100 pairs of breeding Whooper Swans. One of the main interests is in dispersion and the expansion mechanism of Whooper Swans with Lithuanian origin.
The researchers are looking forward to observations which provide very valuable information about Whooper Swan migration and ecology. We would be pleased to receive all observations. The resightings of swans marked in Lithuania can be entered directely into www.geese.org.
Blue neck collars with codes: 1C00-1C99, 2C00-2C99, 3C00-3C99, 4C00-4C99, 6C00-6C99, 0E00-0E99, 1E00-1E99, 2E00-2E99, 3E00-3E99, 4E00-4E99, 5E00-5E99 have been used in Latvia. Please also submit such observations into www.geese.org.
