Family: Accipitridae (Hawks, Eagles, and Kites)
- Shape
- Broad and slightly asymmetrical with a rounded tip; the inner vane is wider than the outer vane, typical of birds of prey needing lift.

Description
A medium-sized hawk known for its 'whistling' call and beautiful rufous-colored shoulders. The feather shows the bold banding that makes this bird easy to identify in flight from below, where it displays translucent 'crescents' near the wingtips.
Colour & Pattern
Strong alternating bands of dark fuscous-brown and creamy white/pale tan. The banding is distinct and fairly sharp with some warm rufous wash near the edges, characteristic of the species' secondary feathers.
Barb Structure
Primarily pennaceous with tightly interlocked barbs that form a firm wind-resistant surface for flight; base exhibits some plumulaceous (fluffy) downy structure near the superior umbilicus.
Texture & Surface
Smooth and firm surface area (vane) with a matte finish. Leading edge is slightly stiffer than the trailing edge to maintain aerodynamic stability.
Key Features
Bold dark and light banding, warm brownish-red tones, and a relatively broad shape for a secondary feather.
Habitat
Bottomland hardwood forests, flooded deciduous woodlands, and suburban areas with nearby woodlots and water sources.
Geographic Range
Common across the eastern United States into southeastern Canada, with a separate population along the coast of California and northern Mexico.
Ecological Role
Secondary predator; controls populations of small mammals, amphibians, and reptiles. Acts as an indicator species for forest health.
Similar Species
Red-tailed Hawk (generally lacks the sharp white banding on secondaries), Cooper's Hawk (narrower feather, different banding spacing), and Broad-winged Hawk (shorter, less distinct banding).
Interesting Facts
Unlike many hawks, Red-shouldered Hawks are very vocal during the breeding season and often return to the same nesting territory for many years.
Condition Notes
Fair to Good; shows typical signs of natural wear and 'feather lice' damage (small holes/fractions in barbs). The calamus is intact, suggesting a natural molt.
