Description
The Red-shouldered Hawk is a medium-sized forest raptor recognized by its reddish-brown shoulder patches, checkered wings, and long banded tail. Adults feature striking reddish barred underparts and bold white-and-black checkerboard patterns on the upperwings. They are vocal birds, often giving a characteristic high-pitched kee-ah call.
Colour & Pattern
Characterized by prominent dark brown or blackish bars alternating with lighter greyish-brown and white checkered or banded patches across the vane, featuring a pale whitish-grey basal area and a stout pale-colored rachis
Barb Structure
Tightly interlocked pennaceous structure with well-developed barbicels and hooklets, small plumulaceous base with a rudimentary or absent afterfeather
Texture & Surface
Stiff, smooth, and matte texture with rigid vanes designed to withstand high aerodynamic pressure during soaring and flapping flight
Key Features
Distinctive alternating dark brown and white/grey barring pattern across a broad, rounded secondary flight feather from a medium-sized raptor
Habitat
Deciduous and mixed forests, often near rivers, swamps, bottomland hardwoods, and flooded plains
Geographic Range
Resident across eastern North America, along the Pacific coast of California, and extending into parts of Mexico
Ecological Role
Apex avian predator playing a vital role in regulating small mammal, reptile, and amphibian populations in forested wetland ecosystems
Similar Species
Broad-winged Hawk and Red-tailed Hawk, distinguished by smaller size compared to Red-tailed and different fine checkered banding patterns compared to Broad-winged
Interesting Facts
Red-shouldered Hawks often use the same nest year after year, frequently adding fresh green sprigs of evergreen or deciduous foliage to the lining
Condition Notes
Good condition with intact barbs and minimal fraying at the tip, showing slight sun bleaching along the outer edges
