Species
Columba livia
Feather Type
Tail feather (rectrix)
Family
Columbidae (Pigeons and Doves)
Shape
Symmetrical with a slightly rounded tip and straight edges.
Size
Approximately 5 to 6 inches (12-15 cm) long; width is approximately 1 inch at the broadest point.
Rarity
Very Common; one of the most abundant bird species in the world.
Color & Pattern
Predominantly medium slate-gray or 'blue' gray. There is a subtle darkening toward the tip, and the ventral side appears slightly lighter and more silver due to structural reflection.
Barb Structure
Tightly interlocked pennaceous barbs along the majority of the vane, with a small plumulaceous (downy) section at the base of the calamus.
Texture & Surface
Smooth, stiff, and somewhat matte. The surface has a slightly powdery texture, typical of pigeons which produce powder down.
Description
This is a classic 'blue' tail feather from a Rock Pigeon. The bird itself is medium-sized with a stout body, short neck, and small head. While plumages vary due to domestication, the wild-type features a gray body with iridescent neck feathers.
Key Features
Symmetrical shape, slate-gray color, white calamus, and the presence of a 'powder down' bloom on the barbs.
Habitat
Primarily urban and suburban environments, but also found in rocky cliffs, agricultural areas, and bridges.
Geographic Range
Global distribution; found on every continent except Antarctica. Mostly non-migratory.
Condition Notes
Good condition. The barbs are mostly intact with minimal fraying at the edges. The calamus is clear, suggesting it was molted naturally.
Interesting Facts
Rock Pigeons were the first bird species to be domesticated by humans over 5,000 years ago. They have an incredible homing ability, using the Earth's magnetic field to navigate.
Ecological Role
Significant prey source for urban raptors like Peregrine Falcons. They also serve as seed dispersers in rural areas.
