Description

The Red-shoulder Hawk is a medium-sized forest raptor recognized by its reddish-brown barred underparts, checkered black-and-white wings, and long banded tail. They are vocal birds often giving a piercing ke-yur call.

Colour & Pattern

Rich warm brown to rufous base with distinctive horizontal or V-shaped white barring and spotting, typical of underparts plumage in a Red-shouldered Hawk

Barb Structure

Pennaceous at the upper distal tip with interlocked barbs, transitioning to plumulaceous (fluffy, downy) structure at the proximal base with reduced barbicels

Texture & Surface

Soft and silky at the base with a stiffer, smooth pennaceous tip; matte surface finish without iridescence

Key Features

Distinctive rufous-brown coloration combined with crisp white spotting and horizontal barring, plus a soft downy base typical of raptor breast contour feathers

Habitat

Deciduous and mixed lowland forests, wooded swamps, river groves, and riparian areas near water

Geographic Range

Eastern North America and a distinct resident population along the coast of California; non-migratory across most of its range

Ecological Role

Apex avian predator controlling small mammal, reptile, and amphibian populations, serving as a key indicator of healthy forest wetland ecosystems

Similar Species

Broad-winged Hawk or Cooper's Hawk, but distinguished by the specific rich rufous tones and bold white barring pattern

Interesting Facts

Red-shouldered Hawks often reuse the same nests year after year, sometimes adding fresh sprigs of evergreen foliage to the structure

Condition Notes

Good condition, showing minor wear and fraying at the distal edges but with an intact rachis and clean barbs
