The greater white-fronted goose (Anser albifrons) is a species of goose, closely related to the smaller lesser white-fronted goose (A. erythropus).

In the United Kingdom and Ireland, it has been known as the white-fronted goose; in North America, it is known as the greater white-fronted goose (or "greater whitefront"), and this name is also increasingly adopted internationally. Even more distinctive are the salt-and-pepper markings on the breast of adult birds, which is why the goose is colloquially called the "specklebelly" in North America.
Greater white-fronted geese are 64–81 cm (25–32 in) in length, have a 130–165 cm (51–65 in) wingspan, and weigh 1.93–3.31 kg (4 lb 4 oz – 7 lb 5 oz).

GBIF citizen-science records
It is estimated from how often the Greater White-fronted Goose is recorded against all the birds logged in Sacramento (877 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
