Buzzard, Common Buzzard
Flight feather (Remiges); specifically a Secondary feather.

Buzzard, Common 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
Broad and somewhat asymmetrical with a rounded tip; the inner vane is wider than the outer vane, giving it a classic bladed secondary shape.
Size
Approximately 18-22 cm in length. This is consistent with the secondary feathers of an adult Common Buzzard which typically range from 15 to 25 cm depending on the specific position (S1-S10).
Rarity
Common; it is one of the most numerous and frequently seen birds of prey across its Palearctic range.

Description

This is a secondary feather from a Common Buzzard, a medium-to-large raptor known for its broad wings and short, fan-shaped tail. The bird itself varies greatly in plumage (from very pale to very dark), but this barred pattern is classic for the species' wing feathers. In flight, they are often seen soaring in thermals, emitting a distinctive feline-like 'mewing' call.

Colour & Pattern

A distinctive 'banded' or 'barred' pattern. The base color is a creamy off-white to pale grey, overlaid with 5-6 broad, dark chocolate-brown horizontal bars. The terminal bar (at the tip) is the widest. The dorsal side is darker and more defined than the ventral side.

Barb Structure

Pennaceous and tightly interlocked throughout the majority of the vane for aerodynamic efficiency, becoming plumulaceous (fluffy) only at the very base near the calamus.

Texture & Surface

The surface is smooth and somewhat stiff to the touch, designed for wind resistance. It has a matte finish with a slight velvety feel characteristic of many raptors, though not as soft as an owl's.

Key Features

Broad dark brown barring on a pale cream background, rounded tip, and a thick, dark-pigmented rachis. The width-to-length ratio identifies it as a secondary rather than a primary feather.

Habitat

Highly adaptable; found in open landscapes such as farmland, moorland, and grasslands, provided there are nearby woods or groups of trees for nesting and roosting.

Geographic Range

Widespread across most of Europe and Asia. Northern populations are migratory, moving to southern Europe or Africa in winter, while southern populations are often year-round residents.

Ecological Role

An essential apex predator and scavenger. They help regulate rodent and rabbit populations and provide a 'sanitary' service by consuming carrion, acting as a key indicator of ecosystem health.

Similar Species

Honey Buzzard (Pernis apivorus) which has different spacing in its bars; Red-tailed Hawk (Buteo jamaicensis) in North America which has different barring patterns; and Rough-legged Buzzard (Buteo lagopus) which usually shows more white at the base.

Interesting Facts

The Common Buzzard is famously variable in color, leading to the saying in some languages that 'no two buzzards are alike.' Despite their fierce appearance, they are opportunistic and will frequent fields to eat earthworms especially after rain.

Condition Notes

The feather appears to be in fair to good condition, likely a naturally molted specimen. There is some separation of the barbs (venting) along the trailing edge, suggesting wear or mechanical stress before it was dropped.
