Canada Goose (occasionally referred to as Cackling Goose in smaller variants)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Anseriformes, Family: Anatidae, Genus: Branta, Species: Branta canadensis · Anatidae (Ducks, Geese, and Swans) · Primary flight feather (remiges), likely P8 or P9 based on the degree of asymmetry
Species
Branta canadensis
Feather Type
Primary flight feather (remiges), likely P8 or P9 based on the degree of asymmetry
Family
Anatidae (Ducks, Geese, and Swans)
Shape
Highly asymmetrical with a very narrow leading edge (outer vane) and a broad trailing edge (inner vane); the tip is rounded to slightly pointed, and the overall outline is elongated and slightly curved.
Size
Estimated at 10-12 inches (25-30 cm) in length. This is consistent with the primary flight feathers of a large-bodied Canada Goose, where primaries range typically from 9 to 13 inches.
Rarity
Very Common; one of the most widespread and easily recognized waterfowl species in the Northern Hemisphere.
Color & Pattern
Uniformly dark fuscous to blackish-brown on the dorsal surface. The ventral side is usually slightly paler/greyer. There are no bars or spots. The base of the barbs near the calamus shows white downy tufts.
Barb Structure
Densely pennaceous and tightly interlocked throughout most of the vane to provide a stiff, wind-resistant surface for flight; plumulaceous (downy) barbs are visible only at the very base (calamus area).
Texture & Surface
The surface is somewhat matte and smooth, with a stiff, rigid vane. The leading edge is particularly sharp and firm to withstand high air pressure during the downstroke.
Description
This is a large, sturdy primary feather from a Canada Goose. The bird itself is characterized by a black head and neck with a distinctive white 'chinstrap' cheek patch, a brown back, and a tan/cream breast. They are known for their massive V-shaped migratory clusters and loud 'honking' calls.
Key Features
Large size, dark brown/black coloration without markings, significant asymmetry of the vanes, and a prominent white/pale rachis.
Habitat
Extremely versatile; found in wetlands, lakes, rivers, ponds, marshes, as well as anthropogenic environments like city parks, golf courses, and agricultural fields.
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.
Condition Notes
Good condition. There is minor separation of the barbs ('split' vanes) near the tip, which is common in naturally molted feathers. No major fault bars or parasite damage is visible.
Interesting Facts
Canada Geese often remain in family groups for at least the first year of the goslings' lives. They are also famous for their 'imprinting' behavior, where hatchlings follow the first moving object they see.
Ecological Role
Primarily grazers, they play a role in nutrient cycling and seed dispersal, though overpopulation in urban areas can lead to eutrophication of small ponds.
Similar Species
Mute Swan (larger, usually white), Wild Turkey (would have distinct barring), or Black Vulture (different vane shape and texture). The color and shaft contrast are diagnostic for Branta.
