Common Raven (also known as the Northern Raven)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Passeriformes, Family: Corvidae, Genus: Corvus, Species: Corvus corax · Corvidae (Crows, Jays, and Ravens) · Primary flight feather (remex), likely from the mid-to-outer wing (P6 or P7)
Species
Corvus corax
Feather Type
Primary flight feather (remex), likely from the mid-to-outer wing (P6 or P7)
Family
Corvidae (Crows, Jays, and Ravens)
Shape
Highly asymmetrical vane with a distinct notch (emargination) on the leading edge toward the tip; pointed to slightly rounded apex; elongated and curved profile
Size
Estimated 28–34 cm (11–13.5 inches). This is significantly larger and broader than a Carrion Crow feather, fitting the heavy wing profile of a Raven.
Rarity
Common in suitable habitat. While once persecuted, they have made a strong recovery in Cornwall and are now a regular sight.
Color & Pattern
Uniform deep iridescent black with a subtle blue-violet or purple sheen visible under direct light. The underside is slightly more matte gray-black. The rachis is also dark pigmented.
Barb Structure
Tightly interlocked pennaceous barbs throughout the distal portion for aerodynamic load; plumulaceous (downy) barbs present at the very base (calamus area); signs of wear and slight separation at the trailing edge
Texture & Surface
Smooth, stiff, and glossy with a high-luster finish. The vane feels rigid to provide lift, with a waxy coating that provides some water resistance.
Description
A massive all-black passerine, the Raven is the world's largest crow. It features a heavy bill, shaggy throat feathers (hackles), and a wedge-shaped tail in flight. Their deep, resonant 'cronk' call is iconic.
Key Features
Large size, deep black pigmentation with structural iridescence, and the specific emarginated shape which allows the bird to spread its 'fingers' while soaring.
Habitat
Found in diverse environments including coastal cliffs (common in Cornwall), moorlands, mountains, and wooded river valleys.
Geographic Range
Widely distributed across the Northern Hemisphere. In the UK, they are year-round residents, particularly abundant in the west and north, including the rugged coastlines of Cornwall.
Condition Notes
Fair to Good. Visible nicks in the trailing edge suggest natural wear from flight or contact with vegetation. Some 'fatigue' lines (fault bars) are absent, suggesting good nutritional health during growth.
Interesting Facts
Ravens are among the most intelligent of all animals, capable of problem-solving, tool use, and even 'mockeries' of other species' calls. They are known to perform acrobatic rolls and dives just for play.
Ecological Role
Apex scavenger and occasional predator; they play a vital role in cleaning the environment and influencing the populations of small mammals and insects.
Similar Species
Carrion Crow (Corvus corone): smaller, less asymmetrical, lacks the deep notch. Rook (Corvus frugilegus): smaller with different base structure.
