- Shape
- Asymmetrical, elongated, and slightly curved with a rounded to slightly pointed tip. The outer vane is narrower than the inner vane, characteristic of steering feathers.

- Approximately 15 to 20 cm (6 to 8 inches) in length; the width is consistent with the rectrices of a large waterfowl species.
- Rarity
- Very Common; often considered an abundant species throughout its range.

Description
These feathers belong to the iconic Canada Goose, a large waterfowl known for its black head and neck with a distinctive white 'chinstrap.' The feathers themselves are robust, designed to withstand the rigors of long-distance migration and frequent aquatic contact. The bird has a wingspan of up to 5.5 feet and is famous for its V-shaped flight formations and loud honking.
Colour & Pattern
Solid dark brown to charcoal-black throughout the majority of the vane, fading to a pale off-white or cream color at the very base near the calamus. No banding or iridescence is present.
Barb Structure
Tightly interlocked pennaceous barbs on the upper two-thirds for aerodynamic integrity, transitioning to soft, plumulaceous (downy) barbs at the base for insulation.
Texture & Surface
The surface is matte and slightly stiff. The pennaceous portion feels smooth and somewhat oily, providing natural water resistance typical of waterfowl.
Key Features
Distinctive contrast between a white, sturdy rachis and a dark brown/black vane; plumulaceous base; slightly asymmetrical shape indicating a tail position.
Habitat
Found in varied environments near water including lakes, ponds, rivers, marshes, and increasingly in urban parks, golf courses, and agricultural fields.
Geographic Range
Native to North America, breeding across Canada and the northern US; widely introduced to Europe, New Zealand, and South America. Many populations are now resident year-round.
Ecological Role
Acts as a major grazer of grasses and aquatic plants; their droppings contribute nutrients to local ecosystems, though in overpopulated urban areas, they can lead to water eutrophication.
Similar Species
Cackling Goose (Branta hutchinsii) feathers are nearly identical but generally smaller. Wild Turkey (Meleagris gallopavo) tail feathers are larger and usually have distinct banding.
Interesting Facts
Canada Geese are known for their strong mate-bonding and will often stay with the same partner for life. They are also famous for their 'V' formation flight which reduces wind resistance for the birds following the leader.
Condition Notes
Good condition. The barbs are mostly intact with minor fraying at the tips and edges, suggesting they were naturally molted rather than lost to trauma.
