- Shape
- Symmetrical to slightly asymmetrical vane with a rounded to bluntly pointed tip. The overall outline is broad and elongated.
- Size
- Approximately 10 to 12 inches long, consistent with a large wing flight feather from a Common Raven, whose remiges typically range from 9 to 14 inches.
- Rarity
- Common and widespread, regularly encountered across its vast geographic range.

Description
The Common Raven is the largest of all pereching birds (passerines). It features a robust heavy bill, shaggy throat hackles, and a wedge-shaped tail visible in flight. Known for its soaring, hawk-like flight and complex vocalizations ranging from deep croaks to metallic bubbling sounds.
Colour & Pattern
Solid glossy black with iridescent blue, purple, and green sheens under bright light. The structural coloration is typical of corvids. The dorsal and ventral surfaces are similar, with the central rachis dark near the tip and fading to a lighter, whitish-grey hue toward the base.
Barb Structure
Tightly interlocked pennaceous vane on the upper portion with hooklets providing structural integrity, transitioning to a semiplumulaceous or fluffy structure near the base of the rachis.
Texture & Surface
Stiff and smooth with a glossy, highly reflective surface on the pennaceous vane, providing aerodynamic rigidity, and softer, downy textures near the base.
Key Features
Large size, deep glossy black coloration with iridescent purple/blue sheen, robust strong rachis fading to white at the base, and stiff pennaceous structure characteristic of corvid flight feathers.
Habitat
Inhabits a wide variety of open and forested habitats, including tundra, sea coasts, mountain ranges, scrublands, agricultural fields, and arid deserts, often nesting on cliff ledges or tall trees.
Geographic Range
Widespread throughout the Northern Hemisphere, found across North America, Europe, and Asia, extending into northern Africa. They are largely non-migratory year-round residents.
Ecological Role
Acting as intelligent apex generalist scavengers and occasional predators, ravens play a crucial role in nutrient recycling and ecosystem health.
Similar Species
American Crow (Corvus brachyrhynchos) or Fish Crow (Corvus ossifragus). Crow feathers are significantly smaller, less robust, and typically lack the impressive scale and heavy white-based rachis of a large raven.
Interesting Facts
Ravens are exceptionally intelligent, capable of solving complex problems, using tools, mimicking human speech, and engaging in playful behaviors like sliding down snowbanks.
Condition Notes
Good condition with minor wear and slight separation along a few barbs in the lower middle section, but overall structural integrity is well-preserved.
