Pileated Woodpecker
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Piciformes, Family: Picidae, Genus: Dryocopus, Species: Dryocopus pileatus
Family: Picidae (Woodpeckers)
- Shape
- Distinctly asymmetrical vane with a noticeable notch or emargination on the leading edge (outer vane); the tip is slightly rounded to pointed.
- Size
- Approximately 18-21 cm (7-8 inches) in length. Comparing to the 1.68-inch golf ball shown, the feather is roughly 4.5 to 5 ball-widths long, which is consistent with adult primary feathers.
- Rarity
- Common in suitable forest habitat, though often heard before seen.

Description
The Pileated Woodpecker is the largest woodpecker in North America (excluding the likely extinct Ivory-billed). It is nearly the size of a crow, characterized by a flaming red crest, black body, and white neck stripes. This primary feather shows the dramatic contrast that makes the bird look like it is 'flashing' white light when it flies.
Colour & Pattern
Striking bicolored pattern: the distal two-thirds of the feather are a solid, deep matte black (melanic), while the basal third features a clean, bright white patch. This creates the 'white underwing flash' seen in flight.
Barb Structure
Densely interlocked pennaceous barbs designed for powerful, undulating flight. The barbs are stiff and robust to withstand the physical stress of drumming and maneuvering through forests.
Texture & Surface
The surface is matte and slightly stiff. It lacks the oily sheen of waterfowl but is very durable. The trailing edge is smooth, while the leading edge shows aerobic shaping (notch).
Key Features
Bicolored black/white primary with a distinct notch; large size (7+ inches) unique among North American woodpeckers; stiff, thick rachis.
Habitat
Mature deciduous and coniferous forests, often with large standing dead trees (snags) for nesting and foraging. Frequently found in mixed woodlands across Maine.
Geographic Range
Year-round resident across much of Canada and the eastern and western United States. Non-migratory but may venture into suburban areas with mature trees.
Ecological Role
Primary cavity nester and keystone species; they control carpenter ant populations and provide housing for numerous other forest animals.
Similar Species
Common Raven feathers are similar in size/color but lack the stark white basal patch. Northern Flicker (Yellow-shafted) feathers have yellow shafts and distinct spotting/crescents, not solid bicoloration.
Interesting Facts
The excavations made by these birds are so large (rectangular holes) that they create vital nesting cavities for other species like Wood Ducks and Screech Owls. Their tongue can extend far beyond their beak to reach ants inside trees.
Condition Notes
Fair to Good. There is significant 'zipper' separation (unzipped barbs) along the trailing edge, likely from impact with the ground or wind. No obvious parasitic damage visible.
