Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Galliformes, Family: Phasianidae, Genus: Gallus, Species: Gallus gallus, Subspecies: G. g. domesticus · Phasianidae (Pheasants, Grouse, and Allies) · Semiplume / Contour (basal portion)
Species
Gallus gallus domesticus
Feather Type
Semiplume / Contour (basal portion)
Family
Phasianidae (Pheasants, Grouse, and Allies)
Shape
Symmetrical, lanceolate to ovate with a ragged, soft tip
Size
Approximately 2.5 to 3.5 cm in length; very small, consistent with a body feather from a medium-sized fowl.
Rarity
Very Common; one of the most abundant bird feathers in human-populated areas.
Color & Pattern
Pure white (leucistic/selected trait). Typical of commercial breeds like Leghorns or White Rocks. No banding or iridescence; the rachis is also white/translucent.
Barb Structure
Plumulaceous (downy) at the base transitioning to loose pennaceous at the tip; lacking strong interlocking hooklets, giving it a fluffy appearance.
Texture & Surface
Soft, downy, and silky. It lacks the stiff, oily texture of waterfowl feathers and the rigid vane of flight feathers.
Description
A small, delicate white feather from a domestic chicken. These birds are heavy-bodied ground-dwellers characterized by fleshy combs and wattles. This specific feather provides thermal insulation rather than flight power.
Key Features
Pure white color, small size, high proportion of downy (plumulaceous) barbs, and a thin, flexible rachis.
Habitat
Agricultural land, backyards, and farms. Not a wild species; found wherever humans keep livestock.
Geographic Range
Global distribution; present on every continent except Antarctica due to human domestication.
Condition Notes
Good condition. The feather appears fresh but slightly ruffled, likely a natural molt or lost during preening.
Interesting Facts
Chickens are the most populous bird on Earth, with a population exceeding 25 billion. They are the closest living relatives to the Tyrannosaurus rex based on molecular protein sequences.
Ecological Role
In a domestic setting, they serve as prey for various meso-predators (foxes, hawks). They are an introduced species impacting local insect populations in farm settings.
Similar Species
Domestic Duck feathers (which are more curved and water-repellent) and Cattle Egret feathers (found in similar habitats but usually stiffer).
