Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Columbiformes, Family: Columbidae, Genus: Columba, Species: Columba livia
Family: Columbidae (Doves and Pigeons)
- Shape
- Asymmetrical with a curved, rounded tip; broad vane that tapers toward the base. The trailing edge is more convex than the leading edge.
- Size
- Estimated 2.0 to 2.5 inches in length. This is consistent with a medium-sized contour feather for an adult Rock Pigeon, which typically measures 12-14 inches in total body length.
- Rarity
- Very Common; one of the most widely recognized and abundant birds in the world.

Description
This feather belongs to the iconic Rock Pigeon, a stout bird with a small head and short legs. While feral populations show varied plumage (white, brown, pied), the slate-gray of this feather is characteristic of the ancestral 'wild type' which features a gray body, two black wing bars, and a white rump.
Colour & Pattern
Uniform slate-gray (blue-gray) base with a subtle transition to a slightly darker leaden gray toward the tip. No distinct banding or spots are visible, though it possesses the matte, dusty finish characteristic of pigeons.
Barb Structure
Pennaceous at the distal end (upper half) with tightly interlocked barbs providing a smooth surface; plumulaceous (downy) at the proximal base for insulation. Barbules are intact with standard hooklets.
Texture & Surface
Smooth, almost silky pennaceous vane with a matte appearance. The lower half is incredibly soft and fluffy. Like most Columbids, the surface has a faint "powder" texture due to specialized powder down feathers elsewhere on the body.
Key Features
Uniform slate-gray color, rounded tip, significant downy base, and a relatively wide vane for its short length.
Habitat
Extremely versatile; originally cliff-dwelling in rocky coastal areas, but now primarily urban and suburban environments, agricultural fields, and city parks.
Geographic Range
Globally distributed. Native to Europe, North Africa, and western Asia, but introduced and established on every continent except Antarctica.
Ecological Role
High-value prey species for urban raptors like Peregrine Falcons and Cooper's Hawks; also acts as an urban scavenger and seed disperser.
Similar Species
Mourning Dove (thinner, more tan/brownish), Eurasian Collared-Dove (lighter gray-buff), or Band-tailed Pigeon (larger, slightly different gray tone).
Interesting Facts
Rock Pigeons were the first birds to be domesticated (over 5,000 years ago) and possess an extraordinary homing ability, using the Earth's magnetic field and sun to navigate home from hundreds of miles away.
Condition Notes
Good condition. The pennaceous distal end is mostly intact, though there is slight separation at the very tip. Some debris is caught in the downy base (plumulaceous section).
