Greater white-fronted goose
Migratory goose with distinctive white forehead and speckled breast.
The greater white-fronted goose (Anser albifrons) is a migratory species of goose, closely related to the lesser white-fronted goose. It breeds in northern Canada, Alaska, Greenland, and Russia, and winters in North America, Europe, and Asia. Named for the white patch of feathers at the base of its bill, it is also known colloquially as the 'specklebelly' in North America due to the salt-and-pepper markings on its breast.

Lore & Background
The greater white-fronted goose is divided into five subspecies. The nominate subspecies, A. a. albifrons, breeds in far northern Russia and winters in Europe and Asia. In North America, three restricted-range subspecies occur: Gambel's white-fronted goose (A. a. gambeli) in interior northwestern Canada, the Pacific white-fronted goose (A. a. frontalis), and the tule goose (A. a. elgasi) in southwest Alaska, the largest and longest-billed of all. The Greenland white-fronted goose (A. a. flavirostris) is much darker overall, with an orange bill and narrow white tail tip, and winters in Ireland and western Scotland. A 2012 study found that A. a. frontalis and A. a. albicans do not merit subspecies status, synonymizing them with A. a. gambeli and the nominate subspecies, respectively.
Reader's Guide
The greater white-fronted goose is significant as a widespread migratory species with distinct subspecies adapted to different Arctic and subarctic breeding grounds. Its populations vary greatly in size: the midcontinent subspecies A. a. gambeli numbered around 710,000 birds in 2010, while the Pacific white-fronted goose numbered about 650,000, and the tule goose only 10,000. The Greenland subspecies is of conservation concern due to a continuous decline in the early 2000s, likely linked to more extreme weather. Ecological studies from 2002 suggest the Greenland birds may warrant recognition as a separate species, partly due to their unusually long period of parental care, possibly unique among Anseriformes. The species is also notable for its high-pitched cackle, described as 'he-he', and for occasional hybridization with snow geese and Canada geese. Its migration patterns and reliance on Arctic breeding windows make it sensitive to climate conditions.
Did You Know?
- The greater white-fronted goose is named for the white patch of feathers bordering the base of its bill; its specific name albifrons comes from Latin albus 'white' and frons 'forehead'.
- In North America, it is colloquially called the 'specklebelly' due to the salt-and-pepper markings on its breast.
- The Greenland subspecies (A. a. flavirostris) has an unusually long period of parental care that may last several years and can include grandparenting, possibly unique among Anseriformes.
- Hybridization with snow geese and Canada geese is occasionally observed.
