Rock Pigeon (also known as Feral Pigeon or Rock Dove)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Columbiformes, Family: Columbidae, Genus: Columba, Species: Columba livia
Family: Columbidae (Pigeons and Doves)
- Shape
- Highly asymmetrical vane with a broad, rounded tip and a slightly curved trailing edge; the outer vane is much narrower than the inner vane.
- Size
- Estimated 8-10 centimeters in length. This is consistent with the secondary wing feathers of an adult Rock Pigeon, which typically range between 7 and 12 cm.
- Rarity
- Very Common; one of the most abundant and easily recognizable bird species in the world.

Description
This is a classic slate-gray wing feather from a Rock Pigeon. The bird itself is medium-sized with a stout body, short legs, and a small head. They exhibit massive color variation due to domestication, but the 'wild type' features a gray body with two black wing bars and iridescent neck feathers.
Colour & Pattern
Uniformly slate-gray or 'pigeon blue' on the dorsal surface with a slightly paler, silvery underside. There is a lack of terminal banding or spotting, which is typical for the gray morph of this species.
Barb Structure
Densely pennaceous throughout most of the vane for aerodynamic integrity, transitioning to a small plumulaceous (downy) base near the calamus (quill). The barbs are tightly interlocked by hooklets.
Texture & Surface
Smooth and somewhat waxy to the touch. The surface has a matte to slightly satiny sheen, designed for water shedding and reducing air friction during flight.
Key Features
Uniform gray coloration, distinct asymmetry of the vanes, rounded tip, and a white, sturdy calamus. Lack of any distinct barring or spots distinguishes it from many raptors or owls.
Habitat
Extremely versatile; found in urban environments, city centers, farms, and rocky seaside cliffs (their ancestral habitat).
Geographic Range
Globally distributed; resident on every continent except Antarctica. They are non-migratory but highly mobile within their local ranges.
Ecological Role
Predominantly a granivore (seed-eater); they serve as a primary prey source for urban raptors like Peregrine Falcons and Cooper's Hawks. They are often considered an indicator of urban environmental health.
Similar Species
Mourning Dove (smaller, more pointed/tapered feathers with buff tones); Eurasian Collared-Dove (grayer but usually shows a different taper and lighter gray-white tips).
Interesting Facts
Rock Pigeons were the first bird species to be domesticated by humans over 5,000 years ago. They possess a remarkable homing ability, using the Earth's magnetic field and scent to find their way home from hundreds of miles away.
Condition Notes
Good condition; the vane is mostly intact with minimal fraying. The white base suggests it was naturally molted recently. No visible fault bars or parasite damage.
