Common Buzzard (also known as Eurasian Buzzard)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Accipitriformes, Family: Accipitridae, Genus: Buteo, Species: Buteo buteo
Family: Accipitridae (Hawks, Eagles, and Old World Vultures)
- Shape
- The feather is broad and slightly asymmetrical, characteristic of a secondary. It features a rounded tip and a gentle curvature of the rachis. The trailing edge (inner vane) is wider than the leading edge (outer vane).
- Size
- Estimated at approximately 18–22 cm in length. This is consistent with the secondary feathers of an adult Buteo buteo, which typically range from 15–25 cm depending on the wing position.
- Rarity
- Common. It is one of the most frequently observed birds of prey in Europe, often seen soaring in thermals or perched on roadside poles.

Description
A medium-to-large raptor with broad, rounded wings and a short tail. Its plumage is famously variable, ranging from almost entirely white to very dark brown. This feather belongs to a typical 'intermediate' morph, showing the classic dark terminal band and white barred inner vanes.
Colour & Pattern
Deep chocolate brown on the outer vane and distal end. The inner vane features a striking pattern of 4-5 bold white transverse bands (mottling) against the brown base. The proximal area near the rachis is notably lighter/white.
Barb Structure
Firmly pennaceous throughout the majority of the vane for aerodynamic integrity, transitioning to plumulaceous (fluffy) barbs at the very base (calamus area). The barbs are well-interlocked but show some slight separation at the tips due to wear.
Texture & Surface
The surface is smooth and somewhat matte, typical of diurnal raptors. It lacks the velvety 'hush' filaments seen in owls, appearing instead stiff and resilient to withstand the pressures of flight.
Key Features
Bold white barring on the inner vane, dark solid tip, broad secondary shape, and a dark rachis in the upper half.
Habitat
Highly versatile; found in open landscapes such as farmland, meadows, and marshes, but requires nearby woodlands or small copses for nesting and roosting.
Geographic Range
Widespread across most of Europe and Asia. Most populations are resident year-round, though northern and eastern birds migrate to southern Europe, Africa, or southern Asia during winter.
Ecological Role
An apex predator and opportunistic scavenger. They provide essential ecosystem services by controlling rodent populations and cleaning up carrion.
Similar Species
Honey Buzzard (Pernis apivorus) has different banding spacing; Red-tailed Hawk (Buteo jamaicensis) feathers are similar but restricted to North America and usually have more distinct fine barred patterns on the secondaries.
Interesting Facts
The Common Buzzard was once heavily persecuted by gamekeepers but has staged a massive recovery. It is known for its 'mewing' call which sounds remarkably like a cat.
Condition Notes
Good condition. There is minor 'penciling' or wear at the very edges of the barbs, suggesting it was likely a naturally molted feather rather than one lost prematurely to trauma.
