Description
A medium-sized woodpecker with a brownish barred back and a black crescent on the chest. In flight, the 'Yellow-shafted' variant reveals brilliant yellow flashes under the wings and tail.
Colour & Pattern
Distinctive yellow-gold to amber-brown pigmentation on the ventral surface and rachis. There is a subtle gradient from a darker tip to a lighter base, with the yellow rachis being a diagnostic trait.
Barb Structure
Densely interlocked pennaceous barbs near the tip for structural integrity, transitioning to plumulaceous (fluffy) down at the very base; rachis is exceptionally rigid.
Texture & Surface
Smooth and glossy on the vane; the rachis feels exceptionally hard and plastic-like compared to most songbird feathers. Leading edge is sharp and stiff.
Key Features
The brilliant yellow-gold rachis (shaft) combined with the stiff, pointed tip characteristic of woodpecker tail feathers.
Habitat
Open woodlands, forest edges, yards, and parks. Uniquely for a woodpecker, they are often found foraging on the ground for ants.
Geographic Range
Common across North America; the 'Yellow-shafted' form is primarily found in the East and North, from the Atlantic coast to the Rocky Mountains.
Ecological Role
Primary cavity nester; they drum and excavate holes that are later utilized by a wide variety of secondary cavity nesters like bluebirds and owls.
Similar Species
Red-shafted Flicker (has orange-red rachis), Gilded Flicker (found in deserts, slightly different yellow hue), and various hawks (lack the stiffened woodpecker rachis).
Interesting Facts
Unlike most woodpeckers that hammer wood for larvae, Northern Flickers primarily eat ants and may consume up to 5,000 ants in a single day.
Condition Notes
Good condition; slight wear visible on the trailing edge. No significant fault bars or parasite damage, suggesting a healthy individual.
