Description

The Red-shouldered Hawk is a medium-sized forest hawk recognized by its reddish-brown barred underparts, distinctive translucent wing panels in flight, and striking checkered black-and-white wings and tail. They are vocal raptors known for their screaming ke-yd calls.

Colour & Pattern

Striking pattern of dark brown or blackish background crossed with bold, contrasting white spots and crescent-shaped bars, characteristic of a Buteo wing feather.

Barb Structure

Tightly interlocked pennaceous structure with strong barbs and barbicels providing aerodynamic rigidity, no afterfeather.

Texture & Surface

Stiff, smooth, and matte with a firm resistance to bending, optimized for aerodynamic performance.

Key Features

Bold black-and-white checkered barring on a brown background, medium size, and stiff aerodynamic structure typical of a Buteo secondary flight feather.

Habitat

Deciduous and mixed lowland forests, swampy woodlands, river groves, and wooded riparian corridors.

Geographic Range

Resident across eastern North America, along the Pacific coast of California, and parts of northeastern Mexico.

Ecological Role

Acts as an apex avian predator controlling small mammal, reptile, and amphibian populations in forested wetland ecosystems.

Similar Species

Broad-winged Hawk and Red-tailed Hawk, though Broad-winged feathers are typically smaller and Red-tailed feathers often feature different tail barring or lack the distinct checkered white spots.

Interesting Facts

Red-shouldered Hawks often reuse the same nest year after year, sometimes adding fresh evergreen sprigs to the structure. They frequently fall victim to nest parasitism or mobbing by smaller birds like Blue Jays and crows.

Condition Notes

Good condition with intact barbs and minimal fraying at the tip, indicating a recently molted feather.
