- Shape
- Asymmetrical with a strong, tapered vane; the outer web is much narrower than the inner web, with a rounded to slightly pointed tip.
- Size

Description
This feather belongs to the Northern Flicker, a large, terrestrial woodpecker known for its unique brown-barred back and black crescent bib. Unlike most woodpeckers, they are frequently seen hopping on the ground eating ants. The 'Yellow-shafted' variant shown here flashes brilliant yellow under the wings and tail during flight.
Colour & Pattern
Distinctive bright yellow/amber rachis and underside. The dorsal vane is blackish-brown with large, rounded white-to-cream spots or indentations along the inner web.
Barb Structure
Tightly interlocked pennaceous barbs on the distal portion for efficient flight; lower proximal portion provides a small spray of plumulaceous (downy) barbs for insulation at the base.
Texture & Surface
Smooth and stiff on the blade; the yellow rachis has a glossy, waxy appearance. The feather surface is matte to slightly satin.
Key Features
The most diagnostic feature is the bright yellow rachis (shaft) combined with large, distinct white spots on a dark brown background on the inner vane.
Habitat
Open woodlands, forest edges, yards, parks, and agricultural lands with scattered trees; frequently found foraging on the ground.
Geographic Range
Common across North America; the 'Yellow-shafted' form is found primarily in the East and North, from the Atlantic coast to the Great Plains and up through Canada and Alaska.
Ecological Role
Primary cavity nester; they excavate holes that are later used by many other species (bluebirds, owls, squirrels). They are major predators of ants and wood-boring larvae.
Similar Species
Red-shafted Flicker has a salmon-red rachis. Pileated Woodpecker feathers are much larger and lack the yellow shaft and specific spotting pattern.
Interesting Facts
The Northern Flicker is one of the few North American woodpeckers that is strongly migratory. They also have a specialized long, barbed tongue that can extend 2 inches past their beak to lap up ants.
Condition Notes
Good condition; the vane shows some minor separation (splitting) near the base, likely from natural wear or the molting process.
