The Lesser White-fronted Goose is a long-distance Palearctic migrant, currently breeding discontinuously in the sub-arctic zone from northern Fennoscandia to eastern Siberia. The wintering/staging areas and migration routes are only partially known. The global population of the Lesser White-fronted Goose has declined rapidly since the middle of the 20th century. The decrease in numbers has been accompanied by fragmentation of the breeding range and is continuing to affect all populations, giving rise to fears that the species may go extinct. Overhunting and habitat loss are considered to be the main threats. BirdLife International estimates a decrease in numbers in the range of 30 % to 49 % during the period 1998 – 2008 (Jones et al. 2008). Not more than 15 individuals are wintering in the territory of Slovakia, therefore this species is considered to be a very rare winter migrant. No breeding of the species was recorded in Slovakia.
