Canada Goose
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis · Anatidae (Ducks, Geese, and Swans) · Primary flight feather (Remex), likely an outer primary (P8 or P9)
Species
Branta canadensis
Feather Type
Primary flight feather (Remex), likely an outer primary (P8 or P9)
Family
Anatidae (Ducks, Geese, and Swans)
Shape
Highly asymmetrical vane; leading edge (outer vane) is much narrower than the trailing edge (inner vane). The tip is slightly pointed to rounded, characteristic of a strong flyer.
Size
Estimated at 8-10 inches (20-25 cm) in length. This is consistent with the primary feathers of a large waterfowl species like the Canada Goose.
Rarity
Very Common; one of the most widespread and easily recognized birds in North America.
Color & Pattern
Muted dark brown to charcoal gray on the upper distal portion, fading into a creamy white or pale gray on the proximal (bottom) half. There is a distinct 'wash' or gradient rather than sharp banding.
Barb Structure
Densely packed pennisetaceous barbs that are tightly interlocked to create a stiff, wind-resistant surface. The base shows some plumulaceous (downy) barbs for insulation near the calamus.
Texture & Surface
Stiff, smooth, and notably oily/waterproof. The surface has a slight matte finish but feels waxy to the touch, an adaptation for life in aquatic environments.
Description
This is a primary flight feather from a Canada Goose, a large waterbird with a distinctive black head and neck 'sock' and a white chin strap. Their wings are broad and powerful, designed for long-distance migration in 'V' formations. They are known for their loud 'honking' calls and assertive behavior near water bodies.
Key Features
Large size, strong asymmetry, thick ivory rachis, and the specific gradient from dark fuscous-brown to a white base without mottling or spots.
Habitat
Extremely versatile: found in lakes, ponds, bays, marshes, grain fields, and frequently in urban parks and golf courses near water.
Geographic Range
Native to North America; breeding across Canada and the northern US, wintering throughout most of the contiguous US and Mexico. Introduced widely in Europe and New Zealand.
Condition Notes
Good condition. The vane is mostly intact, though there is minor separation of the barbs at the very base. The calamus is clear, suggesting it was molted naturally.
Interesting Facts
Canada Geese are known for their lifelong pair bonds. They also undergo a 'molt migration' where non-breeding birds fly far north to safe large bodies of water to replace all their flight feathers at once, during which they are flightless for several weeks.
Ecological Role
Primary grazer of grasses and aquatic plants. They serve as a food source for large predators and contribute significantly to nutrient cycling in wetlands.
Similar Species
Greater White-fronted Goose feathers are similar but often show more mottling. Mute Swan feathers are significantly larger and entirely white. Snow Goose primaries have distinct black tips on white feathers.
