- Shape
- Broadly linear and slightly asymmetrical; the vane is wider on the trailing edge than the leading edge with a rounded, blunt tip.

Description
This feather belongs to the ubiquitous Rock Pigeon, a medium-sized bird with a chunky profile and short legs. This specific feather reflects the 'blue-bar' or 'wild type' plumage, characterized by its slate-gray hue. Pigeons are known for their strong, direct flight and bobbing head movement while walking.
Colour & Pattern
Uniform bluish-gray (often called 'pigeon blue') with a subtle darkening toward the tip. The underside is a lighter silvery-gray. No distinct banding is present on this specific feather, though darker bands are common on Pigeons.
Barb Structure
Densely interlocked pennaceous barbs along the majority of the vane, transitioning to a short, plumulaceous (downy) section near the base (calamus). Typical for flight functionality.
Texture & Surface
Smooth, matte, and slightly waxy to the touch. Pigeons produce a 'powder down' that provides a velvety surface texture and rudimentary waterproofing.
Key Features
Soft bluish-gray coloration, rounded tip, relatively small size for a flight feather, and the characteristic 'pigeon powder' texture.
Habitat
Extremely versatile: favors urban centers, bridges, and agricultural areas, but ancestral habitats include sea cliffs and rock ledges.
Geographic Range
Globally distributed; resident year-round on every continent except Antarctica. They do not migrate but may move locally for food.
Ecological Role
Primary role as a granivore (seed eater) and an important prey source for urban raptors like Peregrine Falcons and Cooper's Hawks.
Similar Species
Mourning Dove (smaller, more pointed tips, brownish hue) and Eurasian Collared-Dove (lighter gray-tan with different tail patterns).
Interesting Facts
Pigeons were the first birds to be domesticated (over 5,000 years ago) and have a remarkable ability to find their way home using magnetic fields and infrasound, a skill used in wartime for carrying messages.
Condition Notes
Fair to Good. There is some minor separation of the barbs (zipper-like gaps) near the trailing edge and base, suggesting it was naturally molted or subject to minor environmental wear.
