Family: Picidae (Woodpeckers and allies)
- Shape
- Asymmetrical vane with a distinctively tapered, rounded tip. The leading edge (outer vane) is much narrower than the trailing edge (inner vane).
- Size
- Approximately 5 to 6 inches in length. This is typical for a mid-wing primary of a medium-sized woodpecker.
- Rarity
- Common; widely distributed and frequently encountered in both wild and developed landscapes.

Description
This feather belongs to the Northern Flicker, a unique woodpecker known for its brownish barred back and spotted underparts. When in flight, the 'Yellow-shafted' Eastern form reveals a flash of brilliant gold under the wings and tail, while the Western 'Red-shafted' form shows salmon-red.
Colour & Pattern
Striking golden-yellow rachis and base of the barbs. The distal ends of the vanes are a soft olive-brown to charcoal-grey, with a faint white spot visible near the tip on the inner vane, characteristic of the species' dorsal pattern.
Barb Structure
Densely pennaceous throughout the main vane with microscopic hooklets (barbicels) maintaining a stiff, aerodynamic surface. The base shows some plumulaceous (fluffy) downy barbs at the calamus.
Texture & Surface
Smooth and glossy on the upper surface; the rachis has a waxy, polished finish. The vane is stiff and resilient, typical of birds that engage in powerful, undulating flight.
Key Features
Diagnostic bright yellow rachis (shaft) paired with olive-grey vanes and a small terminal white spotting pattern.
Habitat
Open woodlands, forest edges, suburban yards, and parks. Unlike many woodpeckers, they are frequently found foraging on the ground.
Geographic Range
Common across Eastern and Northern North America; migratory in the northern parts of their range, moving toward the southern US in winter.
Ecological Role
Primary cavity nester and insectivore; they play a vital role in controlling ant populations and providing nesting sites for other 'secondary' cavity nesters.
Similar Species
Red-shafted Flicker (distinguished by a red rachis) and various hawks, though the yellow shaft is unique to C. auratus auratus in North America.
Interesting Facts
Northern Flickers are one of the few North American woodpeckers that are strongly migratory. They also possess a specialized, long, barbed tongue for extracting ants from underground galleries.
Condition Notes
Good condition; the barbs are mostly intact, suggesting a recent molt or a feather lost during a minor scrape. Minor separation of barbs near the tip is visible.
