Family: Anatidae (Ducks, Geese, and Swans)
- Shape
- Highly asymmetrical with a narrow outer vane and a broad inner vane; the tip is rounded to slightly pointed with a distinct curve toward the tip.
- Size
- Estimated 25 to 35 cm (10-14 inches) in length. This is consistent with the large primary feathers of a heavy-bodied waterfowl like the Canada Goose.
- Rarity
- Very Common; one of the most widespread and easily recognized birds in North America and introduced regions of Europe.

Description
A large waterfowl with a distinctive black head and neck and a white 'cheek' patch. The body is brownish-grey. They are famous for their 'V-formation' flight and loud 'honking' calls.
Colour & Pattern
Predominantly dark brown to charcoal grey. The dorsal surface is darker and more uniform, while the ventral surface (visible) shows a lighter, silvery-grey sheen. The rachis is white to cream-colored.
Barb Structure
Tightly interlocked pennaceous structure throughout the vane for aerodynamic efficiency; plumulaceous (downy) barbs visible at the very base near the calamus.
Texture & Surface
Smooth, stiff, and somewhat oily to the touch for water resistance. The surface has a matte appearance with a slight waxy bloom typical of waterfowl feathers.
Key Features
Large size, highly asymmetrical vane, chocolate-brown coloration, and a notably stout, white rachis that stands out against the dark vanes.
Habitat
Extremely versatile; found in lakes, ponds, rivers, marshes, grain fields, and frequently in urban parks and golf courses.
Geographic Range
Native to North America, breeding from the Arctic to the southern United States. They are migratory but many populations are now year-round residents in temperate zones.
Ecological Role
Primary consumer/herbivore; they help cycle nutrients in wetlands but can cause eutrophication in high densities. Listed as Least Concern by IUCN.
Similar Species
Mute Swan (larger, usually white), Snow Goose (smaller, white), or Greater White-fronted Goose (similar but different tonal quality to the brown).
Interesting Facts
Canada Geese are known for their lifelong pair bonds. They are also incredibly resilient, having recovered from near-extinction in the early 20th century to overpopulation in some areas.
Condition Notes
Good condition. The vanes are largely intact, though there is minor fraying at the tip and edges, suggesting it may have been molted naturally at the end of a season.
