Lesser White-fronted Goose
Encyclopedia
The Lesser White-fronted Goose (Anser erythropus) is a goose
closely related to the larger White-fronted Goose
(A. albifrons).
It breeds in northernmost Asia
, but it is a scarce breeder in Europe
. There is a re-introduction scheme in Fennoscandia
.
The Lesser White-fronted Goose winters further south in Europe and is a rare winter vagrant to Great Britain
. Individual birds formerly appeared regularly at WWT Slimbridge
in Gloucestershire

an breeding grounds. An attractive species, it is also widely kept in wildfowl collections and, as a result, escapes do occur; individuals seen in summer
, or in the company of other feral
geese, are likely to be of captive origin.
The two white-fronted goose species differ little other than in size (the Lesser, at 53–66 cm length and with a 120–135 cm wingspan, is not much bigger than a Mallard
(Anas platyrhynchos) but both may be readily distinguished from the Greylag Goose
by their bright orange legs and their mouse-coloured upper wing-coverts. The Greylag Goose has the bill and legs flesh-coloured, and the upper wing-coverts of a bluish-grey.
Both white-front species have a very conspicuous white face and broad black bars which cross the belly.
Adult Lesser White-fronted Geese, as well as being smaller than White-fronted Geese, have an obvious yellow eye-ring, and the white facial blaze goes up to the crown.
Lesser White-fronted Goose is considered an endangered species
, but there are programmes to reintroduce
animals into the wild to strengthen the population. Additionally it is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA
) applies.
