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
- Relatively broad and rounded with a slight curve; the inner vane is wider than the outer vane, showing moderate asymmetry typical of secondary feathers.
- Size
- Approximately 18-22 cm in length. This size is consistent with the inner secondaries of an adult Buteo buteo.
- Rarity
- Common; the most widespread and frequently seen raptor in Europe and the UK.

Description
This is a classic secondary feather from a Common Buzzard. These birds are medium-to-large raptors with broad, rounded wings and a short neck. Their plumage is famously variable, ranging from almost chocolate brown to very pale, but most show the characteristic 'U' shaped pale breast band and mottled wing feathers like this one.
Colour & Pattern
Muted brownish-grey base with distinct white/pale mottling and irregular banding on the inner vane. The tip is solid brown with a slight subterminal dark wash. The underside is significantly paler, almost silvery-white in the mottled sections.
Barb Structure
Pennaceous structure throughout most of the vane for flight stability, transition to a plumulaceous (downy) base near the calamus for insulation. Barbs are well-interlocked but show some separation at the trailing edge.
Texture & Surface
Smooth and stiff upper surface with a matte finish. The trailing edge is softer than the leading edge. It lacks the velvety 'hush' texture found in owls, indicating a diurnal raptor.
Key Features
Rounded tip, irregular white 'marbling' or bars on the inner vane, and a thick, slightly curved brownish rachis. The lack of distinct, crisp dark bars distinguishes it from a Sparrowhawk or Goshawk.
Habitat
Highly adaptable: found in open deciduous and coniferous woodlands, industrial edges, farmland, and moorlands where there are trees for nesting and open ground for hunting.
Geographic Range
Common across most of Europe and Asia. Non-migratory in temperate regions like the UK, but palearctic populations migrate to Africa and southern Asia for winter.
Ecological Role
An apex predator and opportunistic scavenger. They provide essential ecosystem services by controlling rodent populations and cleaning up carrion.
Similar Species
Red-tailed Hawk (North America) lacks the specific marbling; Honey Buzzard has more distinct, regular dark bands; Goshawk feathers have much crisper, horizontal dark bars.
Interesting Facts
Common Buzzards were once heavily persecuted and became rare in the UK; however, they have staged a massive recovery and are now the most common bird of prey there. They are often seen soaring in thermals, emitting a distinctive cat-like 'mewing' call.
Condition Notes
Good condition. The feather shows minor wear at the edges (fraying) and some separation of the barbs near the base, suggesting it was a naturally molted feather rather than lost through trauma.
