Kingdom: Animalia; Phylum: Chordata; Class: Aves; Order: Galliformes; Family: Numididae; Genus: Numida; Species: Numida meleagris · Numididae (Guineafowl) · Contour feather (Body feather)
Species
Numida meleagris
Feather Type
Contour feather (Body feather)
Family
Numididae (Guineafowl)
Shape
Broadly rounded and symmetrical, with an oval-shaped blade and a large, downy base.
Size
Approximately 2 to 3.5 inches (5-9 cm) in length. This is consistent with flank or back contour feathers for this species.
Rarity
Very Common. They are abundant in the wild across Africa and ubiquitous globally as domestic birds.
Color & Pattern
Distinctive dark brownish-charcoal to black base color heavily marked with crisp, circular white spots (ocelli). The spots are arranged in neat rows along the barbs.
Barb Structure
Hybrid structure: the distal portion is pennaceous with interlocked barbs creating a cohesive vane; the proximal half is plumulaceous (downy), featuring long, loose barbs for insulation.
Texture & Surface
The upper pennaceous section is stiff and smooth with a slight matte sheen, while the lower plumulaceous section is extremely soft, fluffy, and silky to the touch.
Description
A medium-to-large ground-dwelling bird characterized by a featherless, helmet-like bony casque on the head and dark plumage riddled with white spots. They are vocal, gregarious birds that prefer running over flying.
Key Features
Bold white 'polka-dot' spots on a dark grey/black background and a large, fuzzy plumulaceous base.
Habitat
Sub-Saharan African savannas, grasslands, and scrub forests. Often found near water sources and agricultural areas.
Geographic Range
Native to Sub-Saharan Africa. However, they have been widely introduced globally as domesticated poultry and feral populations exist in North America, Europe, and Australia.
Condition Notes
Excellent condition with intact barbs and no signs of heavy wear, suggests a fresh molt or a feather from a protected domestic environment.
Interesting Facts
Guineafowl are known as 'nature's pest control' because they consume massive quantities of ticks and garden pests without scratching the ground as aggressively as chickens.
Ecological Role
Omnivorous foragers that control insect populations and serve as a primary food source for large African predators like leopards and eagles.
Similar Species
Spotted Thick-knee or certain exotic pheasants. However, the specific high-contrast 'polka-dot' pattern is iconic to the Numididae family.
