Canada Goose
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis
Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Highly asymmetrical, elongated, and slightly curved. The leading edge (outer vane) is much narrower than the trailing edge (inner vane). The tip is tapered and slightly rounded.
- Size
- Approximately 10-12 inches (25-30 cm) in length. This is consistent with the primary flight feathers of a large Canada Goose specimen.
- Rarity
- Very Common. One of the most widespread and easily recognized waterfowl in the Northern Hemisphere.

Description
A large, heavy-bodied waterbird with a long black neck and iconic white 'chinstrap' cheek patch. These birds are famous for their V-formation flight patterns and loud 'honking' calls. Their feathers are engineered for powerful long-distance migration.
Colour & Pattern
Predominantly dark brownish-grey to charcoal on the dorsal surface. The ventral side is slightly paler and more silvery. The rachis is creamy white or ivory, providing a sharp contrast against the dark vanes.
Barb Structure
Tightly interlocked and pennaceous for aerodynamic integrity. The barbs are stiff and water-resistant. There is minimal plumulaceous (downy) structure at the very base of the calamus.
Texture & Surface
Smooth, stiff, and somewhat oily to the touch. The surface has a matte to low-gloss finish, designed for water repellency and wind resistance.
Key Features
Strong asymmetry, dark grey-brown vane color, and a distinctively thick, ivory-colored rachis (shaft) that is characteristic of larger Anseriformes.
Habitat
Ubiquitous across North America near water sources including lakes, ponds, bays, marshes, and man-made environments like golf courses, parks, and agricultural fields.
Geographic Range
Native to North America. Breeds across Canada and the northern US; migrates to the southern US and Mexico, though many urban populations are now year-round residents. Introduced to Europe and New Zealand.
Ecological Role
Primarily herbivores that graze on grasses and grains; they act as seed dispersers and are a major prey species for large predators and scavengers. Their presence is often a key indicator of local water quality.
Similar Species
Mute Swan (larger, usually white), Snow Goose (smaller, usually white), or Greater White-fronted Goose (similar but different shaft color/vane width).
Interesting Facts
Canada Geese can fly up to 1,500 miles in a single day if weather conditions are favorable. They are known for their mate-for-life social structure and fierce protection of their goslings.
Condition Notes
Good to Fair. There is some noticeable splitting (separating of barbs) in the trailing vane, likely due to wear or the physical stress of being shed. No obvious signs of parasite damage.
