The Canada Goose is one of the most familiar waterfowl in North America, found across a broad range from the Arctic tundra to the southern United States. In Oregon, they are both year-round residents and migratory visitors, favouring lakes, rivers, and open fields. These geese are easily recognized by their long black necks and distinctive white cheek patches.
Their bodies are typically gray-brown, with a lighter chest and belly, creating a contrast against their darker wings. Their V-shaped flight formations and loud honking calls are iconic sights and sounds during migration. Canada Geese have adapted well to both wild and urban settings, making them a common sight throughout Oregon’s parks and waterways.
Canada Geese are known for their strong attachment to nesting sites, often returning to the same location year after year. They typically build their nests near water, such as ponds, lakes, and rivers, using reeds, grasses, and down feathers to create a cozy, well-insulated nest. The female is the primary builder, while the male stands guard to protect the territory.
Nests are often placed on elevated ground to avoid flooding and provide a clear view of potential predators. Once the nest is ready, the female lays a clutch of 4-7 eggs, which she incubates for about 25-30 days. During this period, the male remains vigilant, chasing off intruders and keeping a close eye on the surroundings, ensuring the safety of the family.
Canada Geese have a varied diet that shifts with the seasons. In spring and summer, they graze on grasses, sedges, and aquatic plants, foraging in fields and along water edges. As fall and winter approach, they often move to agricultural areas to feed on grains, such as corn and wheat, left behind after harvest.
Their ability to digest a range of plant material allows them to thrive in diverse environments, from wild wetlands to urban parks. In urban areas, Canada Geese can often be seen nibbling on lawns and enjoying the abundant greenery. Their dietary adaptability has helped them expand their range, making them a familiar sight in many parts of Oregon, where they can find food sources year-round.
Canada Geese were once in decline due to overhunting and habitat loss in the early 20th century, but concerted conservation efforts have led to a significant recovery. Through habitat protection, regulated hunting, and active management programs, their numbers have rebounded, especially in regions like Oregon.
Their adaptability to urban environments has also played a role in their resurgence, allowing them to establish new populations in city parks and golf courses.

The Brant breeds in the high Arctic and migrates to coastal areas for the winter, with some groups making their way to Oregon’s coastal estuaries and bays. Here, they can be seen resting or feeding along the shorelines, often in tight-knit flocks. Their presence adds a touch of wildness to Oregon’s coastal landscapes, especially when they gather in the sheltered waters of bays and inlets.
Brant geese breed in the harsh conditions of the Arctic, preferring coastal tundra near river deltas and estuaries. They build their nests on the ground, typically using grasses, moss, and down to create a warm, insulated space for their eggs. The female lays 3-5 eggs and incubates them for about 24-26 days, while the male remains nearby to protect the nesting area.
The short Arctic summer means that the goslings must hatch quickly and start feeding to gain strength before their migration south. The family remains close together, and the young learn to swim and forage soon after hatching. Their breeding grounds are remote, adding to the challenge of studying their nesting behaviour.
The diet of the Brant is closely tied to their coastal habitats, both in breeding and wintering grounds. During the breeding season in the Arctic, they graze on grasses and sedges. However, they are most famous for their reliance on marine vegetation, particularly eelgrass and sea lettuce, which they feed on during the winter months.
In Oregon, Brant are often seen along the coast in bays and estuaries, where they forage in shallow waters for aquatic plants. Their diet is highly specialized, making them dependent on the health of coastal ecosystems. Their preference for specific food sources like eelgrass makes them vulnerable to changes in their coastal habitats, making conservation of these areas crucial.
Brant populations have fluctuated over the years, often reflecting changes in the availability of their critical food sources, such as eelgrass beds. Conservation efforts have focused on protecting and restoring these vital coastal habitats. In Oregon, estuarine reserves and protected bays provide important wintering grounds for Brant, allowing them to find food and shelter. Conservationists also monitor their populations closely to ensure that hunting remains sustainable and that their habitats are not threatened by development.
Climate change and habitat degradation pose challenges for Brant populations, but coordinated efforts to protect their wintering and breeding grounds have helped stabilize numbers. Their presence along Oregon’s coasts is a reminder of the delicate balance required to maintain these specialized waterfowl populations.

The Cackling Goose looks much like a smaller version of the Canada Goose, but it has a shorter neck and a more petite bill. It is native to North America, breeding in the tundra regions of Alaska and northern Canada before migrating southward for the winter. In Oregon, Cackling Geese are often seen mingling with Canada Geese in wetlands, fields, and along riverbanks.
Their calls are higher-pitched and more rapid than those of Canada Geese, giving them their distinctive name. Their plumage features similar colors, with a dark head, white cheek patch, and brownish-gray body. Despite their similarities, the smaller size and unique vocalizations of Cackling Geese make them an interesting find during Oregon’s migration season.
Cackling Geese nest in the tundra regions of Alaska and northern Canada, where they select sheltered spots on the ground near water. The female builds a nest out of grasses, moss, and down feathers, which insulate the eggs from the cold ground. She typically lays 3-5 eggs, which are incubated for around 25 days.
The male stands guard nearby, watching for predators like Arctic foxes and gulls. Once the goslings hatch, they quickly leave the nest and begin following their parents to nearby feeding grounds. The short Arctic summer requires the family to be on the move, taking advantage of the brief abundance of food to grow quickly before their migration south.
The diet of the Cackling Goose is similar to that of the Canada Goose, consisting mainly of grasses, sedges, and aquatic plants. During their breeding season in the Arctic, they graze on young shoots and other tundra vegetation. As they migrate to wintering grounds, including Oregon, their diet shifts to include grains from agricultural fields, such as corn and wheat.
Their foraging habits allow them to adapt to different environments, making use of whatever plant material is available. In Oregon’s wetlands and fields, they can often be seen feeding alongside other geese, using their small size and quick movements to find food even in crowded areas.
Cackling Geese were once considered a subspecies of the Canada Goose but were classified as a separate species in 2004 due to differences in size, behaviour, and vocalizations. This change has led to a better understanding of their unique needs and migratory patterns. Their populations are currently stable, but they face challenges from habitat loss in both breeding and wintering areas.
Conservation efforts focus on protecting key wetlands and maintaining healthy migration corridors. In Oregon, where they are a common winter visitor, wildlife managers work to ensure suitable habitats are available for both Cackling Geese and other waterfowl species. This helps maintain their numbers and supports the delicate balance of migratory bird populations.
