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
