Greylag Goose is the largest and bulkiest of the wild geese native to the UK and Europe. Largest numbers of recoveries are from Greylag Geese ringed in Denmark, Britain and Sweden. In November, the Greylag Goose from areas north of the Caspian Sea and in western Siberia move south to areas including Pakistan and India.

Return migration starts early in January, and continues until April. In general, these Greylag Goose travelled distances between 1300 and 1500 km from breeding to wintering areas, stopped at three to six sites and took from 73 to 83 days to travel this distance.
