American Kestrel (Sparrow Hawk)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Falconiformes, Family: Falconidae, Genus: Falco, Species: Falco sparverius · Falconidae (Falcons and Caracaras) · Body Contour Feather

Species
Falco sparverius (Confidence: 95%)
Feather Type
Body Contour Feather
Family
Falconidae (Falcons and Caracaras)
Shape
Symmetrical, lanceolate with a rounded tip and a slightly tapered base.
Size
Approximately 2.5 to 3 inches in length; width is roughly 0.5 inches. This is consistent with dorsal or scapular contour feathers of a small falcon.
Rarity
Common; it is the smallest and most numerous falcon in North America.
Color & Pattern
Rich rufous-cinnamon or burnt-orange on the outer vane, transitioning to a pale cream/white at the base. One partial dark subterminal band/spotting is visible, typical of the kestrel's barred back pattern.
Barb Structure
Mostly pennaceous (tightly interlocked) at the distal end for wind resistance/protection, transitioning to plumulaceous (loose/fluffy) toward the calamus for insulation. Barbules are intact but show minor separation.
Texture & Surface
Smooth and slightly stiff at the tip; soft and downy at the base. The surface has a matte appearance with no iridescence.
Description
This feather belongs to the American Kestrel, a colorful, jay-sized falcon known for its hovering flight while hunting. The species is sexually dimorphic; females have rufous backs with heavier black barring, while males have blue-grey wings. The feather's warm orange hue is a hallmark of this beautiful raptor.
Key Features
Rufous-cinnamon base color, small size, soft plumulaceous base, and diagnostic black subterminal marking characteristic of small North American falcons.
Habitat
Open country including grasslands, meadows, deserts, farm fields, and urban parks with available nesting cavities or boxes.
Geographic Range
Common year-round resident across most of North and South America; northernmost populations (Canada/Northern US) migrate south in winter.
Condition Notes
Good condition; likely a naturally molted feather. Slight ruffling of the barbs near the base but the structure remains sound.
Interesting Facts
American Kestrels can see ultraviolet light, which allows them to track the urine trails of voles and other rodents on the ground, leading them directly to their prey.
Ecological Role
Important secondary consumer; they control populations of insects, small rodents, and occasionally small birds. They are cavity nesters, often relying on woodpecker holes.
Similar Species
Merlin (Falco columbarius) feathers are typically darker/browner without the bright rufous tones. Sharp-shinned Hawk feathers are usually more greyish or barred with white.
