Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Piciformes, Family: Picidae, Genus: Colaptes, Species: Colaptes auratus
Family: Picidae (Woodpeckers)
- Shape
- Asymmetrical, with a pointed tip and a notably stiff, stout rachis. The leading edge is narrower than the trailing edge.
- Size
- Approximately 3.5-4.5 inches in length. This is consistent with the mid-sized flight feathers of a medium-sized woodpecker species.
- Rarity
- Common. Northern Flickers are among the most widespread and frequently seen woodpeckers in North America.

Description
This feather belongs to the Northern Flicker, a large, unique woodpecker known for its terrestrial habits. The bird is brownish overall with black barring on the back and large black spots on the belly. While flying, the flash of yellow under the wings and tail is its most diagnostic field mark.
Colour & Pattern
Striking bicolor pattern: the outer/leading edge and distal tip are deep brownish-black (melanic), while the inner vane and the entire rachis are a vibrant, carotenoid-based chrome yellow.
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane for structural integrity during flight; plumulaceous (fluffy) barbs are present only at the very base near the calamus.
Texture & Surface
The surface is smooth, stiff, and somewhat glossy. The yellow portions have a waxy luster characteristic of woodpecker flight feathers.
Key Features
Bright yellow rachis (shaft), sharp contrast between yellow and blackish-brown vanes, and the characteristic stiffness of a woodpecker feather.
Habitat
Open woodlands, forest edges, yards, parks, and agricultural lands. Unlike many woodpeckers, they are frequently seen foraging on the ground.
Geographic Range
Resident and migratory across Eastern and Central North America, from the treeline in Canada and Alaska south to the Gulf Coast. Intergrades with the 'Red-shafted' form in the Great Plains.
Ecological Role
As primary cavity nesters, flickers create homes that are used by dozens of other species (secondary cavity nesters) like bluebirds and screech-owls, making them a keystone species.
Similar Species
The Red-shafted Northern Flicker (Western US) has similar markings but with salmon-red or pinkish shafts. Yellow-bellied Sapsucker feathers are smaller and lack the bright yellow rachis.
Interesting Facts
Northern Flickers are the only North American woodpeckers that frequently feed on the ground, specifically targeting ants. They use their long, sticky tongues to reach into ant colonies.
Condition Notes
The feather appears in good condition with minor separation of the barbs on the leading edge. It shows minimal wear or sun-fading, suggesting it may be a relatively fresh molt.
