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 · Columbidae (Pigeons and Doves) · Tail feather (rectrix)
Species
Columba livia
Feather Type
Tail feather (rectrix)
Family
Columbidae (Pigeons and Doves)
Shape
Slightly asymmetrical, elongated with a rounded tip; linear but slightly flared toward the distal end.
Size
Approximately 12-14 cm (4.7-5.5 inches) in length, consistent with the tail feathers of a standard adult pigeon.
Rarity
Very Common; one of the most abundant bird species in the world.
Color & Pattern
Slate gray base transitioning to a wide, dark blackish-charcoal subterminal band, finished with a lighter gray/white tip on the outer edge. The pattern is typical of the 'blue-bar' wild-type plumage.
Barb Structure
Pennaceous throughout most of the vane for flight stability; plumulaceous (downy) at the very base for insulation. Barbs are tightly interlocked.
Texture & Surface
Smooth, stiff, and somewhat matte. The surface has a fine, powdery bloom characteristic of Columbidae which aids in waterproofing.
Description
A tail feather from a Rock Pigeon, showing the classic gray and black banding. The bird is medium-sized with a chunky body, small head, and short legs. Wild types are bluish-gray with two black wing bars and a white rump, though domestic varieties show vast color variations.
Key Features
Distinct dark subterminal band on a slate-gray field; presence of 'pigeon powder' on the vane; rounded tip and sturdy rachis.
Habitat
Highly adaptable; found in urban city centers, farmland, rocky cliffs, and coastal areas. Highly dependent on human structures for nesting.
Geographic Range
Worldwide distribution (excepting the high Arctic and Antarctic); originally native to Europe, North Africa, and western Asia, now introduced globally.
Condition Notes
Fair to Good; several 'splits' or separations in the barbs (zips) are visible, and the tip shows mild wear and staining, likely from contact with urban substrate.
Interesting Facts
Pigeons produce a substance called 'crop milk' to feed their young. They were the first birds to be domesticated, dating back over 5,000 years to ancient Mesopotamia.
Ecological Role
Primary consumer of seeds and urban waste; provides a significant food source for urban-adapted raptors like Peregrine Falcons and Cooper's Hawks.
Similar Species
Mourning Dove (smaller, more tapered/pointed tail feathers), Band-tailed Pigeon (stouter, different banding color), or various raptors (which usually have more complex mottling).
