AI-generated identification · may be incorrect

Family: Picidae (Woodpeckers)

Shape
Highly asymmetrical vane; elongated and tapered with a distinctively stiffened, slightly curved rachis. The leading edge is significantly narrower than the trailing edge.
Size
Approximately 18-20 cm (7-8 inches) in length. This is consistent with the primary feathers of a crow-sized woodpecker.

Description

A striking black primary feather from North America's largest extant woodpecker. The bird itself is roughly the size of a crow, featuring a flaming red crest and a massive, chisel-like bill used to excavate deep rectangular holes in trees.

Colour & Pattern

Deep sooty black to brownish-black base. Features diagnostic white 'windows' or patches on the inner vane that create a flash of white in flight. The white is more extensive on the ventral (underside) than the dorsal surface.

Barb Structure

Densely interlocked pennaceous barbs designed for powerful, undulating flight; very rigid texture; minimal plumulaceous (fluffy) down at the very base of the calamus.

Rachis & Barb Pattern

Rachis is thick, particularly at the base, and dark brown to black in color. It is highly rigid to withstand the mechanical stress of drumming and powerful flight.

Texture & Surface

Smooth and glossy on the dorsal surface; leading edge is exceptionally stiff. The feather has a resilient, almost plastic-like feel common to woodpeckers.

Feather Placement

Outer wing (Primary). The strong asymmetry and curved rachis indicate its role as a thrust-generating feather located on the manus (hand) portion of the wing.

Key Features

Deep black color with specific white basal spotting/patching on the inner vane and a very stiff, dark rachis.

Habitat

Mature deciduous or coniferous forests, typically with large standing dead trees (snags) for nesting and foraging.

Geographic Range

Year-round resident across southern Canada, the eastern United States, and parts of the Pacific Northwest.

Ecological Role

Primary cavity nester and insectivore, specifically targeting carpenter ants; serves as an indicator species for forest health and maturity.

Similar Species

American Crow (lacks white patches), Common Raven (larger, all black), Northern Flicker (smaller, different shaft color and patterns).

Interesting Facts

Pileated Woodpeckers play a vital role as 'ecosystem engineers,' creating large cavities that are later used by dozens of other species, including owls, ducks, and swifts.

Cultural Significance

Woodpecker feathers, especially those with such bold colors, have historically been used in indigenous adornments and ceremonies in North America.

Field Identification Tips

Look for these feathers near large standing snags or at the base of trees with fresh, deep rectangular excavations.

Condition Notes

Good condition with minor wear at the tip. The calamus is clear, suggesting a natural molt rather than a forced removal by a predator.
