Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis
Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Highly asymmetrical vane characteristic of flight feathers, with a notched leading edge (emargination) and a tapered, slightly rounded tip.
- Size
- Approximately 10-12 inches (25-30 cm) in length. This size is consistent with an adult Canada Goose primary feather, which typically ranges from 9 to 14 inches.
- Rarity
- Very Common; one of the most widespread and easily recognizable waterfowl in the Northern Hemisphere.

Description
A large, heavy-bodied waterfowl with a long black neck and distinctive white 'chin strap' cheek patch. Their brownish-grey plumage provides perfect camouflage when nesting in marshes, while their powerful wings allow for long-distance V-formation migration.
Colour & Pattern
Uniformly dark fuscous-brown to charcoal grey on the dorsal side, appearing lighter/silvery-tan on the ventral underside due to light reflection. No banding or spots, which is diagnostic for this species.
Barb Structure
Densely packed pennaceous barbs with interlocking hooklets for aerodynamic integrity; transitions to plumulaceous (downy) structure at the base near the calamus.
Texture & Surface
Stiff and slightly waxy texture for water resistance; the surface has a matte appearance with a faint satiny sheen when viewed at certain angles.
Key Features
Large size, dark chocolate-brown coloration without barring, strong asymmetry in the vane, and a notched leading edge near the tip.
Habitat
Ubiquitous in temperate regions: lakes, ponds, marshes, grain fields, and frequently urban parks, golf courses, and suburban lawns near water.
Geographic Range
Native to North America, breeding from the Arctic/sub-Arctic to the southern US. Highly migratory in the north; many populations are now year-round residents in temperate zones.
Ecological Role
Primary consumer/herbivore; they play a significant role in nutrient cycling between aquatic and terrestrial environments and serve as a prey source for large predators.
Similar Species
Mute Swan feathers (all white), Sandhill Crane (more grey/tapered), and Wild Turkey (heavily barred with white). The lack of pattern distinguishes it from most raptors.
Interesting Facts
Canada Geese are known for their 'V' flight formation, which allows the birds behind to benefit from the lift created by the wingtip vortices of the bird in front, increasing flight range by up to 71%.
Condition Notes
Good to Excellent condition. The barbs are mostly zipped together, though there is slight separation (fraying) near the base and trailing edge, suggesting a naturally molted feather.
