Family: Accipitridae (Hawks, Eagles, and Kites)
- Shape
- Broad and rounded with a distinctively blunt tip; slightly asymmetrical vane typical of secundaries
- Size
- Approximately 12-15 cm (4.5-6 inches) in length, consistent with the mid-sized flight feathers of a small accipiter

Description
This feather belongs to the smallest hawk in the US and Canada. The Sharp-shinned Hawk is a master of maneuverability, featuring short, rounded wings and a long, squared-off tail that acts as a rudder through dense foliage. They are characterized by their 'flap-flap-glide' flight pattern and piercing orange-to-red eyes in adults.
Colour & Pattern
Slate-gray to bluish-gray base on the dorsal surface with 4-5 distinct dark brownish-black horizontal bands (bars). The underside is paler silvery-white with muted barring
Barb Structure
Tightly interlocked pennaceous barbs throughout most of the vane; plumulaceous (fluffy) structure near the base of the calamus for insulation
Texture & Surface
Smooth and somewhat stiff surface with a matte finish; the leading edge is slightly more rigid to withstand air pressure during flight
Key Features
Distinctive dark bands on a gray background, blunt rounded tip, and a relatively small size for a raptor feather
Habitat
Primarily deep coniferous or mixed forests and thickets; frequently found in suburban areas near bird feeders during winter
Geographic Range
Extensive range across North America, from the tree line in Alaska and Canada through the US and into Central America; northern populations are migratory
Ecological Role
Top-tier avian predator. They play a vital role in regulating songbird populations and serve as an indicator of forest health
Similar Species
Cooper's Hawk (Accipiter cooperii) feathers are very similar but generally larger with more rounded tail feathers; American Kestrel (Falco sparverius) feathers have more rufous/orange tones
Interesting Facts
These birds are specialized hunters of small songbirds. They are known to use the 'accipiter squeeze' to dispatch prey and have extremely thin, 'sharp' shins which give them their common name
Condition Notes
Fair to Good. Shows significant wear and 'zipper' gaps where barbs have separated. Likely a naturally molted feather or one lost during a predatory struggle
