Cooper's Hawk (Chicken Hawk)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Accipitriformes, Family: Accipitridae, Genus: Accipiter, Species: Accipiter cooperii
Family: Accipitridae (Hawks, Eagles, and Kites)
- Shape
- Symmetrical to slightly asymmetrical with a rounded tip and straight edges; typical of a medium-sized raptor tail feather.
- Size
- Estimated 7-9 inches (18-23 cm) in length. This is consistent with the tail length of an adult Cooper's Hawk, which ranges from 14 to 20 inches in total body length.
- Rarity
- Common; one of the most widespread and frequently seen hawks in North American urban and suburban environments.

Description
This feather belongs to the Cooper's Hawk, a medium-sized raptor known for its agile flight through dense trees. Adults have blue-gray backs and rufous-barred underparts, while this tail feather shows the characteristic 'barred' look used for identification in flight.
Colour & Pattern
Distinctive bold banding with alternating thick dark brownish-gray (charcoal) and lighter silvery-white to pale gray bands. The tip typically features a narrow white terminal band, which is visible here but slightly worn.
Barb Structure
Pennaceous; tightly interlocked barbs creating a stiff, wind-resistant vane. The base shows a small plumulaceous (downy) section for insulation. Barbs are generally intact with minor fraying at the tip.
Texture & Surface
Smooth and stiff upper surface with a matte finish. The vane is firm but flexible enough to withstand high-speed flight through woodland canopy.
Key Features
Wide, even dark-and-light banding and a relatively straight, narrow shape. Much larger than a Sharp-shinned Hawk feather but similarly patterned.
Habitat
Mixed forests, woodlots, and increasingly common in suburban backyards where they hunt at bird feeders.
Geographic Range
Year-round resident throughout much of the United States and Mexico; northern populations migrate south from Canada during winter.
Ecological Role
Apex predator of small-to-medium birds and mammals. They help control populations of starlings, pigeons, and rodents.
Similar Species
Sharp-shinned Hawk (smaller, thinner bands), Red-shouldered Hawk (more narrow white bands), and Northern Goshawk (much larger, more mottled gray).
Interesting Facts
Cooper's Hawks are 'accipiters' or forest hawks; they have short wings and long tails that act like a rudder, allowing them to chase prey through thick brush at high speeds.
Condition Notes
Good condition. There is minor wear at the distal tip (apical fraying), likely from contact with vegetation while hunting. No visible fault bars.
