Common Raven (also known as 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 characteristic of a primary flight feather; the trailing (inner) vane is much broader than the leading (outer) vane. The tip is rounded and shows slight emargination.
- Size
- Estimated 25–32 cm (10–12.5 inches) in length based on proportions. This is significantly larger and broader than a typical American Crow feather.
- Rarity
- Common in appropriate habitat, though less abundant than Crows in highly urbanized areas of the Eastern US.

Description
A magnificent, large black feather belonging to the world's largest passerine. The Common Raven is a massive, all-black bird with a heavy bill and shaggy throat feathers. In flight, they are distinguished by their wedge-shaped tails and aerobatic soaring ability.
Colour & Pattern
Uniform iridescent black with a deep violet or blue-green sheen visible at certain angles. The ventral/underside surface is slightly more matte gray-black. The rachis is dark pigment-heavy but fades to a pale, translucent cream color at the calamus base.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for aerodynamic integrity. The base shows a small amount of plumulaceous (downy) structure near the calamus.
Texture & Surface
Smooth, stiff, and glossy. The surface has a waxy feel that provides water resistance and reduces friction during flight.
Key Features
Large size, deep black iridescence, asymmetrical wing-feather shape, and a notably long, pale, translucent calamus (quill) which is a hallmark of large corvids.
Habitat
Extremely versatile; found in coniferous forests, deserts, mountain tundra, coastal cliffs, and increasingly in rural or even urban environments.
Geographic Range
Widespread across the Northern Hemisphere (Holarctic). Found throughout North America, Europe, Asia, and North Africa. In North America, they are resident from Alaska to Mexico.
Ecological Role
Apex scavenger and occasional predator. They play a vital role in cleaning up carrion and are important indicators of ecosystem health due to their wide range.
Similar Species
American Crow (Corvus brachyrhynchos) feathers are similar but significantly smaller (less than 9 inches) and less robust. Black Vulture feathers have a lighter, silver-gray underside to the primary tips.
Interesting Facts
Ravens are among the most intelligent animals on Earth, capable of problem-solving, tool use, and even 'planning' for future events. They can mimic human speech and are prominent in the mythology of many indigenous cultures.
Condition Notes
Excellent condition. The vane is intact with no significant fraying or 'fault bars' (which would indicate nutritional stress during growth). Minor wear at the very tip suggests it was naturally molted.
