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 vane with a narrow leading edge and a broader trailing edge. The tip is slightly tapered/pointed, characteristic of high-altitude soaring and maneuverability.
- Size
- Estimated 10-14 inches (25-35 cm) in length. This is significantly larger and sturdier than a standard American Crow feather, which typically maxes out at 8-9 inches.
- Rarity
- Common in appropriate habitat, though less frequent in heavily urbanized Eastern US cities compared to the American Crow.

Description
The Common Raven is the largest passerine (perching bird), nearly the size of a Red-tailed Hawk. It is distinguished by its massive bill, shaggy throat feathers (hackles), and wedge-shaped tail in flight. This feather reflects the bird's power and intelligence, designed for complex aerial acrobatics.
Colour & Pattern
Uniformly deep oily black. In direct sunlight, these feathers exhibit a characteristic iridescent violet, blue, or greenish sheen due to structural coloration rather than pigment alone. The rachis is also dark black.
Barb Structure
Tightly pennaceous and interlocked with strong barbicels to withstand high wind pressure during flight. Minimal plumulaceous (downy) structure at the base of the calamus.
Texture & Surface
Smooth, stiff, and somewhat glossy. The surface has a waxy feel that provides water resistance, typical of large corvids.
Key Features
Large size, deep black coloration with violet iridescence, extreme vane asymmetry, and a very thick, rigid rachis.
Habitat
Extremely versatile: found in coniferous forests, high deserts, mountains, coastal cliffs, and arctic tundras. Increasingly adapted to rural and suburban environments.
Geographic Range
Holarctic distribution. Found throughout the Northern Hemisphere, across North America from the Arctic to Nicaragua, and across Eurasia and North Africa.
Ecological Role
Apex scavenger and opportunistic predator. They play a vital role in cleaning ecosystems and are often the first to locate carrion, signaling other scavengers.
Similar Species
American Crow (Corvus brachyrhynchos) - Crow feathers are smaller, less rigid, and lack the intense violet sheen. Chihuahuan Raven (Corvus cryptoleucus) - Nearly identical but slightly smaller and usually has white bases at the neck feathers.
Interesting Facts
Ravens are among the most intelligent animals on Earth, capable of problem-solving, tool use, and even 'recruiting' wolves to carcasses. They can mimic human speech and other bird calls better than many parrots.
Condition Notes
Fair to Good. The feather appears slightly worn at the edges with some separation of barbs (zip-like structure), suggesting it was molted after a full season of use.
