Canada Goose
Flight feathers (remiges). Specifically, the left feather is a Primary, the middle is a Secondary, and the right is likely a Tertial or inner Secondary.

Canada Goose

Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis

Family: Anatidae (Ducks, Geese, and Swans)

Shape
Highly asymmetrical vanes characteristic of flight feathers. The outer vane is very narrow and stiff to resist air pressure, while the inner vane is wider and rounded. The tips are gently rounded to blunt.
Size
Approximately 7-9 inches (18-23 cm) in length. These are consistent with feathers from a medium-to-large waterfowl; Canada Goose primaries typically range from 8 to 11 inches depending on the specific subspecies.
Rarity
Very Common. One of the most widespread and easily recognized waterfowl species in the world, often occurring in large, conspicuous flocks.

Description

These feathers belong to a large, heavy-bodied waterbird known for its iconic black head and neck with a white 'chinstrap'. The Canada Goose has a brownish-gray body, a pale breast, and large, powerful wings suited for long-distance migration in 'V' formations. They are loud, social birds with a distinctive honking call.

Colour & Pattern

Predominantly dark charcoal gray to brownish-black. The leftmost feather features a distinct white distal tip (apex), which is common in domestic breeds or certain plumage variations. The ventral side (underside) is slightly lighter and more silvery-grey than the dorsal side.

Barb Structure

Densely packed and tightly interlocked pennaceous barbs. The high barbule density creates a wind-resistant, cohesive surface necessary for powerful flight. The base of the feathers shows a small amount of plumulaceous (downy) structure near the calamus.

Texture & Surface

The surface is smooth, firm, and slightly oily to provide water repellency. The vanes are stiff and produce a characteristic 'zipping' sound when the barbs are separated and re-aligned with a finger.

Key Features

Large size, dark gray/black coloration, high asymmetry of the vanes, and the distinct stiff texture typical of heavy waterfowl flight feathers. The white tip on the first feather is a diagnostic marker of specific individual variation or domestic influence.

Habitat

Found in a wide variety of habitats including lakes, ponds, rivers, marshes, city parks, golf courses, and agricultural fields. They are highly adaptable to human-altered landscapes.

Geographic Range

Native to North America, breeding across Canada and the northern United States. Most populations are migratory, wintering throughout the US and northern Mexico. They have also been introduced to Europe, New Zealand, and parts of Asia.

Ecological Role

They act as significant grazers of aquatic and terrestrial vegetation. Their droppings cycle nutrients into wetlands, though in high urban densities, they can cause water quality issues. They are prey for large raptors and ground predators.

Similar Species

Similar to feathers from the Cackling Goose (Branta hutchinsii), which are virtually identical but smaller. Also similar to Mute Swan flight feathers, though swan feathers are typically pure white.

Interesting Facts

Canada Geese are known to stay together for life (monogamous). During their annual summer molt, they lose all their flight feathers at once and are flightless for about six weeks, often remaining near water for safety during this time.

Condition Notes

Good overall condition. The middle feather shows some separation of the barbs (splits), likely due to mechanical wear or the molting process. The calamus ends appear clean, suggesting these were naturally molted feathers rather than pulled.
