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 such as P9 or P10
Species
Branta canadensis
Feather Type
Primary flight feather (remex), likely an outer primary such as P9 or P10
Family
Anatidae (Ducks, Geese, and Swans)
Shape
Highly asymmetrical with a very narrow, stiff outer vane and a broad inner vane. The tip is pointed and the overall shape is elongated/falcate, designed for aerodynamic efficiency.
Size
Approximately 10 to 12 inches in length. This is consistent with the standard range for an adult Canada Goose primary, which typically measures 25-30 cm.
Rarity
Very Common. One of the most widespread and easily recognizable waterfowl in North America.
Color & Pattern
Solid brownish-black to charcoal grey on the dorsal surface. The ventral side is slightly paler and more silvery-grey. The color is consistent throughout the vane, with no banding or spots, typical of adult plumage.
Barb Structure
Densely pennaceous and tightly interlocked with robust barbicels (hooklets) to create a windproof surface. The proximal end shows a small amount of plumulaceous (downy) structure near the calamus.
Texture & Surface
Very stiff and smooth. The surface has a slight waxy or oily sheen, which provides water resistance. The leading edge (outer vane) is exceptionally rigid to resist air pressure.
Description
This is a large, sturdy primary feather from a Canada Goose. The bird is a large waterbird with a distinctive black head and neck 'sock' contrasted by a white 'chinstrap.' They have brownish backs and wings with pale underparts. Known for their 'honking' calls and V-shaped flight formations, they are a hallmark of North American wetlands and urban waterways.
Key Features
Large size, dark brownish-black coloration, extreme asymmetry of the vanes, and a very stiff, thick rachis that turns white at the base.
Habitat
Extremely versatile; found in lakes, ponds, bays, marshes, fields, and increasingly in urban parks, golf courses, and suburban lawns.
Geographic Range
Native to North America, breeding across Canada and the northern US. Many populations are now permanent residents throughout the lower 48 states; others migrate to the southern US and Mexico.
Condition Notes
The feather appears to be in relatively good condition, though there is some minor separation of the barbs (splits) near the base and mid-vane, likely due to natural wear or handling after being molted.
Interesting Facts
Canada Geese often mate for life and are highly protective of their nests. They exhibit a 'molt migration' where non-breeding birds fly north to large bodies of water where they can safely lose all their flight feathers at once and remain flightless for several weeks.
Ecological Role
Primary grazers that can significantly influence plant community structure. They serve as a food source for large predators and contribute to nutrient cycling in aquatic environments.
