Common Raven (Northern Raven)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: Corvus corax · Corvidae (Crows, Jays, and Magpies) · Flight feather (Remex); likely a primary flight feather from the outer wing.
Species
Corvus corax
Feather Type
Flight feather (Remex); likely a primary flight feather from the outer wing.
Family
Corvidae (Crows, Jays, and Magpies)
Shape
Asymmetrical vane typical of flight feathers, with a narrow leading edge and a broader trailing edge. The tip is rounded to slightly pointed, with a tapered overall outline.
Size
Approximately 10-12 inches (25-30 cm) in length. This is consistent with the primary feathers of a large Corvid, which typically range from 9 to 13 inches.
Rarity
Common and widespread within its range, though less frequent in the central and southeastern United States compared to the American Crow.
Color & Pattern
Uniformly iridescent black with subtle blue or violet sheen under direct light. The underside is slightly more matte gray-black. There are no bands or spots, which is characteristic of adult ravens.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for flight efficiency, transitioning to a small plumulaceous (fluffy) section at the very base. The barbs near the bottom are significantly worn and separated.
Texture & Surface
Smooth and relatively stiff. The surface is semi-glossy due to structural coloration (iridescence). The trailing edge shows significant wear and separation of the barbs.
Description
This is a large, sturdy flight feather from a Common Raven. The bird is the largest passerine, characterized by its all-black plumage, wedge-shaped tail, and thick, powerful beak. Ravens are known for their soaring flight and deep, croaking calls. This feather reflects the bird's size and the physical demands of its powerful flight style.
Key Features
Large size (larger than a crow's primary), uniform black coloration with oily iridescence, and a heavy, thick central rachis.
Habitat
Extremely versatile; found in evergreen and deciduous forests, high deserts, coastal cliffs, tundra, and increasingly in urban or suburban environments.
Geographic Range
Widespread throughout the Northern Hemisphere, across North America, Europe, Asia, and North Africa. In North America, they are found from the Arctic to Nicaragua.
Condition Notes
Fair to Poor. The feather shows significant mechanical wear; the barbs are separated or 'unzipped' along the lower half of the rachis. The tip remains mostly intact, but the overall structure indicates an old feather that was likely molted.
Interesting Facts
Ravens are among the most intelligent of all birds, capable of problem-solving, tool use, and even social manipulation. They have a vocal repertoire of over 30 distinct categories of sounds.
Ecological Role
Ravens are vital apex scavengers and opportunistic predators. They help clean ecosystems of carrion and affect prey populations. They are also known for 'leading' larger predators like wolves to carcasses.
Similar Species
American Crow (Corvus brachyrhynchos) feathers are similar but significantly smaller (usually under 8-9 inches) and less robust. Black Vulture primaries have white/silvery patches at the base.
