Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: C. corax
Family: Corvidae (Crows, Jays, and Ravens)
- Shape
- Relatively symmetrical with a broad, rounded tip and a slightly curved trailing edge. The vane is wide and lacks the deep notches found in primary wing feathers.
- Size
- Approximately 7-9 inches (18-23 cm) in length and 1.5-2 inches in width. This size is consistent with standard raven secondary feathers, which are significantly larger than those of a crow.
- Rarity
- Common and widespread, though less frequent in heavily developed agricultural flatlands compared to the American Crow.

Description
A large, jet-black passerine with a thick bill and shaggy throat feathers. This feather reflects the raven's mastery of the air, being robust and structurally sound. Ravens are known for their massive 4-foot wingspans and wedge-shaped tails.
Colour & Pattern
Uniformly iridescent black. Depending on the light, a subtle blue or violet sheen may be visible on the dorsal surface. The ventral side is a more matte, charcoal grey. There are no bands or spots.
Barb Structure
Densely packed and interlocked (pennaceous) throughout most of the vane for flight efficiency, with a small plumulaceous (fluffy) section near the base (calamus) for insulation.
Texture & Surface
Smooth and glossy on the upper surface with a slightly oily, water-repellent finish. The leading edge is stiff to cut through the air, while the trailing edge is softer.
Key Features
Large size, uniform deep black coloration with iridescence, and a thick, dark rachis. Lack of white at the base of the barbs distinguishes it from some other corvids.
Habitat
Extremely versatile: found in coniferous and deciduous forests, mountains, deserts, coastal cliffs, and increasingly in urban or agricultural environments.
Geographic Range
Holarctic distribution. Resident throughout the Northern Hemisphere including North America, Europe, Asia, and North Africa. Generally non-migratory.
Ecological Role
An apex scavenger and opportunistic predator. They clean up carrion and help control populations of small mammals, playing a vital role in nutrient cycling.
Similar Species
American Crow (smaller, less glossy), Chihuahuan Raven (white bases on neck feathers), and Black Vulture (different texture, usually lighter grey on the underside).
Interesting Facts
Ravens are among the most intelligent of all animals, capable of using tools, solving complex puzzles, and even mimicking human speech better than some parrots.
Condition Notes
The feather appears to be in Good condition, likely a recently molted specimen. There is some minor separation of the barbs near the tip, possibly from hitting vegetation or landing.
