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 outer primary (P8-P10)

Species
Branta canadensis
Feather Type
Primary flight feather (remex), likely outer primary (P8-P10)
Family
Anatidae (Ducks, Geese, and Swans)
Shape
Highly asymmetrical with a very narrow leading vane and broad trailing vane; elongated with a curved rachis and tapered tip.
Size
Estimated 10-14 inches (25-35 cm) in length. This is consistent with the large primary feathers of a Canada Goose, which typically exceed 8 inches.
Rarity
Very Common; one of the most widespread and easily recognizable waterfowl species in the world.
Color & Pattern
Uniform dark grayish-brown (sepia) on the dorsal surface with a slightly lighter, silvery-gray ventral surface. The rachis transitions from white at the base to dark brown/black toward the tip.
Barb Structure
Tightly interlocked pennaceous barbs for aerodynamic rigidity, with a downy plumulaceous section at the base (superior umbilicus) for insulation.
Texture & Surface
Smooth, stiff, and somewhat oily/waterproof. The surface has a slight matte-to-satin sheen typical of waterfowl plumage.
Description
This is a large, sturdy primary flight feather from a Canada Goose. The bird is known for its black head and neck with a white 'chinstrap.' These feathers are engineered for powerful, sustained flight during long migrations.
Key Features
Large size, dark brown color without banding, extreme vane asymmetry, and a very thick, stiff rachis.
Habitat
Found in a wide variety of habitats including lakes, ponds, bays, marshes, fields, and increasingly in urban parks and golf courses.
Geographic Range
Native to North America; resides year-round in much of the U.S., with northern populations migrating to the Arctic to breed. Also introduced to Europe and New Zealand.
Condition Notes
Good condition. There is minor fraying at the tip and some separation of the barbs ('zipper' effect), which is typical for a molted feather. No signs of parasites.
Interesting Facts
Canada Geese fly in a V-formation to reduce wind resistance for birds behind the leader. They are known to stay with the same mate for life.
Ecological Role
Primarily a herbivore that grazes on grasses and aquatic plants. They serve as an important prey species for large carnivores and help in nutrient cycling.
Similar Species
Similar to feathers of other large dark geese (like the Cackling Goose, which has smaller feathers) or a Wild Turkey (which usually has distinct barring).
