Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Galliformes, Family: Numididae, Genus: Numida, Species: N. meleagris · Numididae (Guineafowl) · Contour (Body feather)
Species
Numida meleagris
Feather Type
Contour (Body feather)
Family
Numididae (Guineafowl)
Shape
Broadly rounded and nearly symmetrical; typical semi-spatulate contour feather outline with a plumulaceous base.
Size
Approximately 3.5 to 4.5 centimeters in length; typical for a flank or breast contour feather of this species.
Rarity
Very Common. While native to Africa, these feathers are ubiquitous in agricultural and domestic settings worldwide.
Color & Pattern
Striking black-to-dark-charcoal base color with prominent, regularly spaced, circular white dots (polka dots). The downy base is a uniform smoky grey.
Barb Structure
The distal half is pennaceous with interlocked barbs; the proximal half is highly plumulaceous (downy) for insulation.
Texture & Surface
The patterned tip is smooth and slightly glossy; the lower half is soft, airy, and matte. The feather is fairly stiff for its size.
Description
This is a classic contour feather from a Helmeted Guineafowl. The bird is known for its plump, slate-grey body covered in these white spots, a bare, blue-and-red head, and a bony yellow 'helmet' or casque on its crown.
Key Features
Unique white 'polka dot' pattern on a black background and a large, fluffy, grey downy base. No other common bird has this specific circular spot density.
Habitat
Savannahs, scrublands, and open agricultural fields; widely domesticated and found on farms or in urban parks globally.
Geographic Range
Native to sub-Saharan Africa. Introduced populations are found in North America, Europe, and Australia as poultry or semi-wild residents.
Condition Notes
Excellent condition; the barbs are mostly intact throughout the pennaceous region, indicating a freshly molted or lost feather with minimal wear.
Interesting Facts
Guineafowl are known as 'nature's alarm system' because they emit loud, harsh calls at the sight of predators. They are also famous for their diet, which includes large quantities of ticks and lime-disease-bearing insects.
Ecological Role
Terrestrial foragers that control insect populations and serve as a prey source for larger raptors and caracals in their native range.
Similar Species
Spotted Crake or certain woodpeckers, but those lack the large downy base and have different spot distributions or barred patterns.
