Northern Flicker (Yellow-shafted form), Common Flicker
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Piciformes, Family: Picidae, Genus: Colaptes, Species: Colaptes auratus
Family: Picidae (Woodpeckers)
- Shape
- Asymmetrical with a narrow leading vane and a wider trailing vane; the tip is acutely pointed and slightly stiffened, a characteristic trait of woodpeckers used for structural support.
- Size
- Estimated at 4.5 to 5.5 inches in length. This is consistent with the primary feathers of a medium-sized woodpecker like the Northern Flicker.
- Rarity
- Common; one of the most widespread and frequently encountered woodpeckers in North America.

Description
This feather belongs to the Northern Flicker, a large, brownish woodpecker with a black bib and spotted belly. In flight, the flash of gold (or red in western forms) under the wings is a diagnostic mark. They have a barred back and a white rump patch visible as they fly away.
Colour & Pattern
Distinctive bright golden-yellow to amber-toned rachis and inner vane. The leading edge of the outer vane is a dark olive-brown to fuscous. The underside appears more brilliantly yellow than the dorsal surface due to structural pigments.
Barb Structure
The distal portion is tightly interlocked (pennaceous) for flight efficiency, while the proximal base near the calamus shows loose, fluffy (plumulaceous) barbs for insulation. The barbs are stiff and dense.
Texture & Surface
Smooth and glossy on the upper surface; the rachis has a waxy, polished texture. The trailing edge is softer than the leading edge, which is stiff and resilient.
Key Features
The brilliant yellow shaft (rachis) combined with the dark outer vane and pointed woodpecker-style tip is diagnostic for the Yellow-shafted form of the Northern Flicker.
Habitat
Open woodlands, forest edges, yards, and parks. Unlike most woodpeckers, they are frequently found on the ground in grassy areas foraging for ants.
Geographic Range
The 'Yellow-shafted' form is found across Eastern and Northern North America, from the Atlantic coast to the Rocky Mountains and north into Alaska and Canada. Many populations are migratory.
Ecological Role
Primary cavity nester that provides homes for many secondary cavity-dwelling species like bluebirds and owls. They are also significant controllers of ant and beetle populations.
Similar Species
Red-shafted Flicker (distinguished by reddish/salmon pink shafts); Gilded Flicker (found in desert Southwest, smaller and paler); Yellow-bellied Sapsucker (smaller, lacks the solid yellow rachis throughout).
Interesting Facts
The Northern Flicker is the only North American woodpecker that frequently feeds on the ground, using its long, slightly curved bill and sticky tongue to lap up ants from the soil.
Condition Notes
Fair to Good. There is some separation of the barbs (zipper-like effect) near the mid-vane, likely from physical impact or handling. The calamus is intact, suggesting a natural molt.
