The white-fronted goose (Anser albifrons) is a medium-sized goose species that breeds in the northernmost reaches of North America and Eurasia. There are several subspecies that are all considered white-fronted geese, though there are some key physical differences between them. Here we’ll take a closer look at the characteristics that define this goose species and what differentiates the various subspecies from each other.
Physical Characteristics of White-Fronted Geese
There are a few key physical features that are characteristic of white-fronted geese and set them apart from other goose species:
- White forehead patch – All subspecies have a distinctive white patch on their forehead, giving them their common name. This white patch extends from the base of the bill and wraps around the forehead.
- Pink bill and feet – Their bills are pink with a dark nail, and their feet are also pinkish in color.
- Yellow eye ring – They have a distinctive yellow or orange eye ring.
- Gray body plumage – Their main body feathers are dark gray-brown in color with light gray fringes.
- Black barring on belly – They have distinctive black barring or stripes on their breast and belly.
- Size – They are a medium-sized goose, smaller than a Canada goose but larger than a brant. Length ranges from 23-29 inches, wingspan 52-59 inches.
- Call – They have a nasally croaking call that sounds like “ank ank.”
In addition to these shared physical traits, there are some differences between the subspecies in size and color intensity. However, the white forehead patch, pink bill, yellow eye ring, gray plumage, and black belly barring are consistent features that define the white-fronted goose.
Subspecies of White-Fronted Goose
There are five main subspecies of the white-fronted goose that are recognized today:
European White-Fronted Goose (A. a. albifrons)
This subspecies breeds across northern Europe and Asia and winters from Europe to China and Japan. They are the largest of the white-fronted goose subspecies with pinkish-orange legs and feet. Their white face patches also tend to be more extensive. Their belly barring is narrow and sparse.
Pacific White-Fronted Goose (A. a. frontalis)
Native to western North America, this subspecies winters along the Pacific coast from southern Alaska to California. They are medium in size with yellowish legs and feet. Their white face patches are more restricted. Their belly bars are thick and extensive.
Tule White-Fronted Goose (A. a. elgasi)
This smallest subspecies breeds in Alaska and winters in California’s Central Valley. They have yellow-orange legs and feet and less distinctive facial patches. Their barring is heavy like the Pacific subspecies.
Greenland White-Fronted Goose (A. a. flavirostris)
A rare subspecies that breeds in western Greenland and winters in Ireland and Scotland. It has a more orange bill and pinkish feet and legs. Its white face patch fades during winter. Belly barring is moderate.
Gambel’s White-Fronted Goose (A. a. gambeli)
This subspecies migrates between Alaska and California and the Pacific Northwest. It is medium-sized with orange feet and legs. Its white face patch is oval-shaped and belly barring is moderate to heavy.
While there are some subtle variations between these subspecies, they all share the definitive white forehead patch along with other key physical traits that identify them as white-fronted geese.
Range and Habitat
White-fronted geese nest in the northernmost regions of North America and Eurasia. Their breeding grounds stretch across tundra and low arctic coastlines from Alaska to eastern Siberia. They migrate along flyways that take them to more southern wintering grounds.
The different subspecies have distinct wintering ranges:
- European white-fronted geese – Winter from Western Europe to China
- Pacific white-fronted geese – Winter along the Pacific Coast from California to Mexico
- Tule white-fronted geese – Winter in California’s Central Valley
- Greenland white-fronted geese – Winter in Ireland and Scotland
- Gambel’s white-fronted geese – Winter from California to the Pacific Northwest
During winter and migration, white-fronted geese frequent a variety of wetland habitats including marshes, wet meadows, pond and lake edges, and agricultural fields. They nest on the ground, often on islands, peninsulas or slopes near water.
Diet
White-fronted geese are omnivores, eating a variety of plant and animal matter. Their diet consists mainly of:
- Grasses
- Sedges
- Agricultural grains like corn, wheat, rice and barley
- Aquatic plants
- Invertebrates like mollusks, crustaceans, and insects
They are considered an agricultural pest in some regions where they forage on crops. They use their strong bills to dig and uproot plants from the ground. During breeding season, they rely more heavily on protein-rich foods to meet energy demands.
Migration
White-fronted geese are strongly migratory, making annual north-south journeys between their arctic breeding areas and more temperate wintering grounds. In North America, there are three primary flyways used by these geese during migration:
- Pacific Flyway – Along the west coast between Alaska and Mexico
- Central Flyway – Through the Great Plains between the Arctic and Gulf Coast
- Mississippi Flyway – Follows the Mississippi River corridor
Some key staging and wintering sites along these flyways include:
- Midwinter sites in California’s Central Valley
- Klamath Basin on the California-Oregon border
- Summer Lake basin in Oregon
- Yellowstone River in Montana
- Platte River in Nebraska
- Gulf Coastal marshes in Texas and Louisiana
These geese migrate in flocks of a few dozen to thousands of birds. Migration begins in September and October, with the birds arriving on the winter grounds by November and December. They make the return trip north in March through May.
Reproduction and Lifespan
White-fronted geese reach sexual maturity by 2-3 years of age. They are monogamous, pairing up with a mate who they will likely remain partnered with for life. Nesting begins in late May or early June depending on latitude.
The female lays a clutch of 3-6 eggs and incubates them for 22-24 days while the male stands guard. The goslings hatch and are able to leave the nest soon after, feeding themselves on available vegetation. The young fledge at 6-7 weeks old and become capable of flight a week or two later.
The goslings remain with their parents through their first winter migration. The maximum recorded lifespan for wild white-fronted geese is over 24 years, but averages are lower at 10-12 years.
Population Status
Overall white-fronted goose populations are abundant and stable. The global population is estimated at around 2.5 million individuals. However, a couple subspecies have experienced population declines and are of higher conservation concern:
- The Greenland white-fronted goose has a tiny population of around 35,000 birds that was once on the brink of extinction. Ongoing conservation efforts have stabilized its numbers.
- The Tule white-fronted goose has declined to about 10,000 individuals due to habitat loss in its limited California wintering range.
The other more common subspecies numbering in the hundreds of thousands to millions are rated as species of Least Concern by the IUCN. Hunting is regulated to maintain sustainable harvest levels of these abundant goose populations.
Significance to Humans
White-fronted geese have long been valued by humans both as a food source and asquarry for hunting. Native American tribes like the Inuit relied on these geese as part of their subsistence lifestyle. Today they remain an important waterfowl game species in North America and Europe.
These geese are also of cultural significance to some Native American tribes who integrate them into stories, art, and ceremonies. Their seasonal migration coincides with important ceremonial dates on some tribal calendars.
Conservation programs focused on subspecies like the Greenland white-fronted goose also have an ecotourism component. Birdwatchers will travel to see the rare geese wintering in Scotland and Ireland, bringing in tourism revenue.
Agriculturally, the geese are considered a pest in some regions where they feed on crops. Their grazing can impact yields of rice, wheat, corn, and other grains. But in other areas, their foraging provides a beneficial natural vegetation control.
