Lesser White-fronted Goose
The Lesser White-fronted Goose (Anser erythropus) is a close relative to the larger White-fronted Goose (A. albifrons). During times of breeding it is widely distributed throughout northernmost Asia, but is less common in Europe. This migratory bird spends its winters further south in Europe and is a very rare vagrant to Great Britain.
Very few difference are noted between the two white-fronted goose species, the most notable being size. Tthe 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-colored upper wing-coverts.
Both white-front species have a very noticeable white face and broad black bars crossing the stomach. Adult Lesser White-fronted Geese also have an obvious yellow eye-ring, and the white facial blaze goes up to the crown.
This species is considered endangered, but there are programs in place to reintroduce animals into the wild in order to strengthen the population.
