Description

The Cooper's Hawk is a medium-sized forest-dwelling hawk known for its stealthy hunting style, short rounded wings, and long tail adapted for high-speed navigation through dense timber. Adults feature slate-gray backs, reddish-barred underparts, and striking red eyes, while juveniles are brown with heavily streaked chests. They are agile aerial hunters specializing in catching medium-sized birds and mammals.

Colour & Pattern

Striking slate-gray to brownish-gray background with bold, clean white chevron or barred markings across the vane, featuring a pale whitish-gray base and a pale straw-colored rachis

Barb Structure

Pennaceous upper vane with tightly interlocked barbicels, transitioning into a plumulaceous (fluffy, downy) base without hooklets

Texture & Surface

Smooth, firm, and slightly glossy on the upper pennaceous portion, transitioning to soft, silky, and loose down at the base

Key Features

Distinct slate-gray and stark white alternating bands or chevron markings on a rounded-tip contour feather, characteristic of dorsal plumage in medium-sized accipiters

Habitat

Deciduous, mixed, and coniferous forests, forest fragments, wooded swamps, and increasingly in suburban neighborhoods, urban parks, and golf courses

Geographic Range

Widely distributed across North America, breeding from southern Canada down throughout the United States and into Mexico; northern populations migrate south for the winter

Ecological Role

Apex avian predator in woodland and suburban ecosystems, playing a crucial role in regulating populations of songbirds, doves, and small mammals while serving as an indicator of environmental health

Similar Species

Sharp-shinned Hawk feathers can appear nearly identical but are typically smaller; larger Buteo hawks (like the Red-tailed Hawk) have significantly larger, broader feathers with different banding patterns

Interesting Facts

Cooper's Hawks are exceptional aerial acrobats, capable of high-speed pursuits through thick forest canopies where they frequently crash through branches in pursuit of prey without injury, protected in part by bony ridge structures over their eyes

Condition Notes

Good condition with intact barbs along the pennaceous vane and minimal wear, suggesting a relatively fresh molt or fallen feather with clean structure
