Canada Goose
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: canadensis
Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Highly asymmetrical vane, elongated and tapered toward a slightly rounded tip, with a characteristic curvature along the rachis.
- Size
- Approximately 10-12 inches (25-30 cm) in length. This is consistent with the outer primaries of a large Canada Goose; inner primaries are typically shorter.
- Rarity
- Very Common. One of the most widespread and easily recognizable birds in North America.

Description
This feather belongs to the Canada Goose, a large waterbird with a distinctive black head and neck, white 'chinstrap' cheek patch, and brownish-grey body. They are famous for their V-shaped flight formations and loud 'honking' calls.
Colour & Pattern
Overall dark brown to charcoal grey on the dorsal surface with a slight silvery-grey sheen on the ventral surface. The rachis is light ivory or white near the base, darkening to brown toward the tip.
Barb Structure
Tightly pennaceous and interlocked for aerodynamic efficiency. The leading edge (outer vane) is very narrow and stiff to provide structural support during the downstroke of flight.
Texture & Surface
Stiff and smooth with a slight oily, water-repellent coating characteristic of waterfowl. The vane is rigid and produces a 'velcroid' sound when the barbs are separated and zipped back together.
Key Features
Large size, dark charcoal-brown coloration, extreme asymmetry of the vane, and a thick white calamus (quill base).
Habitat
Extremely versatile: found in wetlands, lakes, ponds (such as those in Bend, OR), rivers, grassy parklands, and agricultural fields.
Geographic Range
Native to Arctic and temperate regions of North America; widely migratory, though many urban populations are now year-round residents.
Ecological Role
Primary herbivore in wetland ecosystems; they help regulate aquatic vegetation but can also contribute to nutrient loading in small urban lakes. They serve as a food source for large predators like Bald Eagles and coyotes.
Similar Species
Greater White-fronted Goose (smaller, lighter brown), Cackling Goose (nearly identical but smaller feathers), or Tundra Swan (much larger and pure white).
Interesting Facts
Canada Geese are known for their strong pair bonds and loyalty to their birthplaces, often returning to the same nesting site year after year. They are one of the few species that has benefited significantly from human-altered landscapes like golf courses and lawns.
Condition Notes
Good condition, though there is visible 'zippering' or fraying along the trailing edge, likely due to contact with vegetation or the stress of flight before it was molted.
