Cackling Goose

The Cackling Goose is a small, compact goose that looks like a miniature version of the Canada Goose, with the same black head and neck and bold white chinstrap, but a shorter neck, a stubby triangular bill, and an overall daintier build. Once classified as a subspecies of the Canada Goose, it was recognized as a full species based on genetic and morphological differences.

Cackling Geese breed on Arctic and subarctic tundra and winter in large flocks in the interior and coastal United States, often mixing with the more numerous and larger Canada Goose.

Key field marks

• Small size with a short neck and a stubby, steep, triangular bill
• Black head and neck with a white chinstrap patch, essentially identical in pattern to Canada Goose
• Rounded head shape and compact, almost duck-like body proportions

Similar species

The Canada Goose shares the same head pattern but is larger overall with a longer neck and a longer, more sloped bill; separating the two, especially mid-sized Canada Goose subspecies from large Cackling Goose subspecies, can be genuinely challenging and relies on subtle structural differences and direct size comparison in mixed flocks.

Cackling Geese breed on Arctic and subarctic tundra in Alaska and parts of northern Canada, nesting on the ground near ponds, coastal marshes, and tundra wetlands. They winter primarily in the interior valleys and coastal areas of the western and southern United States, often in large flocks that also include Canada Geese, favoring agricultural fields, wetlands, and open grasslands.

Behavior

Highly social, forming large wintering flocks often mixed with Canada Geese; behavior is broadly similar to that species, including grazing on land and strong pair bonds.

Voice

Gives a higher-pitched, more yelping or cackling call than the deeper honk of the Canada Goose, which helps distinguish mixed flocks by ear.

Feeding

Grasses, sedges, grains, and other plant material, grazed on land and in shallow wetlands.

Nesting

Nests on the ground on Arctic and subarctic tundra, often close to water; clutches typically hold 3-6 eggs.
