Cooper's Hawk

Species

Accipiter cooperii

Feather Type

Contour (Body Feather)

Family

Accipitridae (Hawks, Eagles, and Kites)

Shape

Symmetrical, rounded tip, spatulate-to-ovate outline

Size

Approximately 2 to 3 inches in length; typical for a flank or secondary covert contour feather of an adult hawk.

Rarity

Common; one of the most frequently seen hawks in North American suburban environments.

Color & Pattern

Strong horizontal banding (barring). Consists of alternating dark charcoal/slate gray and bright white bars. The tip is white. This high-contrast barring is characteristic of adult Accipiter plumage.

Barb Structure

Pennaceous on the upper two-thirds with a well-defined vane; plumulaceous (downy) at the base for insulation.

Texture & Surface

Smooth and firm at the tip; soft and silky at the base. Matte finish typical of raptor body feathers.

Description

This feather comes from a medium-sized hawk known for its agility in flight. The adult bird features a blue-gray back and a crown that contrasts with a lighter nape. Its breast is horizontally barred with rufous or gray, as seen in this specimen. They have long, banded tails and piercing red or orange eyes.

Key Features

High-contrast horizontal gray and white barring; white tip; symmetrical silhouette; plumulaceous base.

Habitat

Woodlands, forested edges, and increasingly common in suburban backyard areas with mature trees.

Geographic Range

Year-round resident across much of the United States and Mexico; northern populations migrate south from Canada in winter.

Condition Notes

Excellent condition; barbs are fully intact with no visible fault bars or parasite damage; appears to be a fresh molt.

Interesting Facts

Cooper's Hawks are 'true hawks' or 'accipiters,' specialized for hunting birds mid-air. They can fly through dense vegetation at high speeds using their long tails as rudders.

Ecological Role

Apex avian predator; controls populations of smaller birds and mammals; indicator of healthy woodland ecosystems.
