Description
These are tail feathers from a Cooper's Hawk, a agile forest hunter. The bird is medium-sized with broad, rounded wings and a long tail. Adults have a dark 'cap' on the head, blue-gray back, and reddish-barred underparts.
Colour & Pattern
Heavy dark brown or charcoal-gray horizontal banding (bars) against a light gray or off-white background; the tip may show a thin white terminal band.
Barb Structure
Pennaceous and tightly interlocked toward the tip and outer vane for flight stability, becoming plumulaceous (downy) at the base for insulation.
Texture & Surface
Smooth and firm on the pennaceous portion with a matte finish; soft, downy texture at the base near the quill.
Key Features
Distinctive wide dark bands (typically 3-4 visible) and a rounded tip distinguish it from the Sharp-shinned Hawk, which typically has a squared-off tail.
Habitat
Found in various wooded habitats, including deciduous, mixed, and coniferous forests, as well as leafy suburban parks and backyards.
Geographic Range
Year-round resident throughout much of the United States and Mexico; northern populations migrate to the southern U.S. and Central America for winter.
Ecological Role
Apex predator of small to medium-sized birds and mammals; helps regulate prey populations in both forest and urban ecosystems.
Similar Species
Sharp-shinned Hawk (Accipiter striatus) feathers are very similar but smaller with narrower bands; Northern Goshawk (Accipiter gentilis) feathers are larger and more heavily mottled.
Interesting Facts
Cooper's Hawks are specialized bird hunters; they are famous for their maneuverability through dense brush and are often seen raiding bird feeders.
Condition Notes
Excellent condition; the vanes are intact with minimal wear or fraying, likely freshly molted.
