Family: Accipitridae (Hawks, Eagles, and Kites)
- Shape
- Slightly asymmetrical, elongated, and rounded at the tip. The vane width is relatively uniform until tapering near the base.
- Size
- Estimated 7.5 to 9 inches (19-23 cm) in length. This is consistent with a mature adult Cooper's Hawk's central or intermediate rectrix.
- Rarity
- Common; one of the most widespread and frequently encountered hawks in North American urban and suburban environments.

Description
A medium-sized hawk specialized for high-speed maneuvers through dense canopy. Adults have blue-gray backs and rufous-barred underparts. This feather displays the classic 'banded' tail pattern that identifies the genus Accipiter.
Colour & Pattern
Features 3-4 wide, dark brownish-gray/charcoal horizontal bands alternating with much lighter, off-white to pale gray bands. The tip is broad and dark, finished with a thin white terminal band which is characteristic of the species.
Barb Structure
Mostly pennaceous (tightly interlocked) throughout the length of the vane with a small plumulaceous (downy) section at the superior umbilicus (base).
Texture & Surface
Smooth and stiff on the pennaceous vane, designed for aerodynamic durability. The surface is matte with a slight waxy bloom typical of raptor feathers.
Key Features
Bold charcoal-brown horizontal banding, rounded tip with a white terminal edge, and a length exceeding that of the similar Sharp-shinned Hawk.
Habitat
Found in various woodland types, from deep forests to leafy suburban parks and backyards, where they hunt smaller birds.
Geographic Range
Common across North America, from Southern Canada through the United States to Central Mexico. Northern populations are migratory.
Ecological Role
Apex avian predator of small-to-medium birds and mammals; serves as a vital natural control for local bird populations.
Similar Species
Sharp-shinned Hawk (smaller, usually squared-off tail tip, narrower bands) and Northern Goshawk (much larger, more irregular mottling/wavy bands).
Interesting Facts
Cooper's Hawks are 'true hawks' or 'accipiters'. They are notorious for frequenting bird feeders, not for the seeds, but to hunt the songbirds that gather there.
Condition Notes
Excellent condition. No visible fault bars or parasite damage; the edges are sharp, indicating it was likely a fresh molt.
