Canada Goose (Honker, Greater Canada Goose)
Secondary flight feather (remex), likely S5 or S6 position

Canada Goose (Honker, Greater Canada Goose)

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

Family: Anatidae (Ducks, Geese, and Swans)

Shape
Slightly asymmetrical with a rounded-to-blunt tip; the outer vane is narrower than the inner vane. The overall outline is broad and rectangular, típica of anseriform wing feathers.
Size
Approximately 7-9 inches (18-23 cm) in length. This is consistent with the secondary feathers of a large subspecies of Canada Goose, which typically range from 6 to 10 inches depending on the specific position on the wing.
Rarity
Very Common. One of the most widespread and easily recognizable birds in North America.

Description

This is a large, sturdy feather from a Canada Goose, a bird characterized by a black head and neck with a distinctive white 'chinstrap.' Geese are heavy-bodied waterfowl with long necks and large webbed feet. They are famous for their V-formation flight patterns and loud 'honking' vocalizations during migration.

Colour & Pattern

Dense brownish-gray to charcoal base color on the outer vane and distal half of the inner vane. The proximal portion of the inner vane transitions to a lighter, silvery-gray or tan wash. There is no distinct banding, which is a diagnostic feature for this species compared to raptors.

Barb Structure

The distal portion is pennaceous with tightly interlocked barbs (velcro-like) for aerodynamic surface stability. The base (proximal) features soft, loose plumulaceous barbs for thermoregulation. The barbs are mostly intact but show some minor separation in the mid-vane.

Texture & Surface

The surface is matte with a slightly waxy/oily feel, common in waterfowl for water repellency. The vane is stiff and rigid to withstand the pressures of flight, though the trailing edge is softer than a primary feather.

Key Features

Solid brownish-gray coloration without banding; white/creamy rachis; broad, rounded profile; and fluffy white down at the base of the quill.

Habitat

Found in a wide variety of habitats including lakes, ponds, bays, marshes, grain fields, and frequently in urban/suburban parks, golf courses, and lawns.

Geographic Range

Native to Arctic and temperate regions of North America; widely introduced to Europe, New Zealand, and South America. Northern populations are migratory, while many suburban populations are year-round residents.

Ecological Role

Primary grazers that serve as important seed dispersers. They are also a significant prey species for large predators such as coyotes and eagles, and their presence can significantly alter the nutrient balance of small water bodies.

Similar Species

Mallard (smaller, more iridescent/blue on secondaries), Snow Goose (pure white rachis and vanes), Cackling Goose (nearly identical but significantly smaller in scale).

Interesting Facts

Canada Geese are known to mate for life. They are highly protective parents and can become quite aggressive if humans or predators approach their goslings. Some populations have lost the instinct to migrate due to the abundance of food in urban landscapes.

Condition Notes

Fair to Good condition. There are prominent gaps (splits) in the vane, likely caused by mechanical wear or the molting process. The tip shows slight fraying, suggesting it is an older feather shed during a natural molt.
