Common Raven (Northern Raven)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: Corvus corax
Family: Corvidae (Crows, Jays, and Ravens)
- Shape
- Highly asymmetrical with a distinct notch or emargination on the leading edge (vane); elongated with a rounded to slightly pointed tip.
- Size
- Estimated 25–32 cm (10–12.5 inches) in length; the width is broad at the base and narrows significantly due to the emarginated leading edge.
- Rarity
- Common; though they are less abundant than crows in urban centers, they are widespread and easily found in appropriate wilder habitats.

Description
This is a massive flight feather from a Common Raven, the largest passerine (perching bird). Ravens are heavy-billed, all-black birds with wingspans reaching up to 4.5 feet. They are known for their wedge-shaped tails and incredible aerobatic soaring capabilities compared to the floppier wingbeats of crows.
Colour & Pattern
Uniformly deep black with a subtle blue or violet iridescent sheen visible under direct light; the underside is slightly more matte gray-black; no banding or spots.
Barb Structure
Densely pennaceous (interlocked) throughout the main vane for aerodynamic integrity; plumulaceous (downy) at the very base (calamus area) for insulation.
Texture & Surface
Smooth and glossy on the dorsal surface; stiff and rigid to withstand the pressures of flight; the leading edge feels particularly sharp and firm.
Key Features
Large size (significantly larger than a crow feather), deep black coloration with iridescence, and a very pronounced notch (emargination) on the leading vane side.
Habitat
Extremely versatile: found in coniferous forests, coastal cliffs, deserts, tundra, and increasingly in rural or suburban environments.
Geographic Range
Widely distributed across the Northern Hemisphere (Holarctic); permanent resident from the high Arctic through North America, Europe, Asia, and North Africa.
Ecological Role
Apex scavenger and occasional predator; they play a vital role in nutrient cycling by cleaning up carcasses and dispersing seeds.
Similar Species
American Crow (smaller, lacks deep emargination), Chihuahuan Raven (smaller, white base to neck feathers, different range), Turkey Vulture (much larger, silver-gray undersides).
Interesting Facts
Ravens are among the most intelligent animals on Earth, capable of problem-solving, tool use, and even 'recruiting' wolves to carcasses so the wolves can open the hide for them.
Condition Notes
Good condition; minor ruffling of the barbs on the trailing edge suggests a naturally molted feather; the calamus is clear, typical of a finished growth cycle.
