American Kestrel (also known as the Sparrow Hawk)
Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Falconiformes, Family: Falconidae, Genus: Falco, Species: Falco sparverius · Falconidae (Falcons and Caracaras) · Contour (body feather), specifically from the upper back (mantle) or scapular region.
Species
Falco sparverius
Feather Type
Contour (body feather), specifically from the upper back (mantle) or scapular region.
Family
Falconidae (Falcons and Caracaras)
Shape
Symmetrical with a rounded, broad tip; the overall outline is somewhat ovoid or teardrop-shaped at the distal end, transitioning to a loose, downy base.
Size
Approximately 1.5 to 2.5 inches in length. This is consistent with a scapular or mantle feather for an American Kestrel, which is North America's smallest falcon.
Rarity
Common. It is the most widespread and numerous falcon in North America, though populations have seen declines in recent decades in certain regions.
Color & Pattern
Warm rufous (reddish-brown) base color. It features a distinctive bold black subterminal spot or partial bar near the tip. The very base of the feather transitions to a smoky grey or white downy texture.
Barb Structure
The distal half is pennaceous (tightly interlocked), while the lower half is plumulaceous (downy and loose) for insulation. The individual barbs are fine and show typical diurnal raptor structure.
Texture & Surface
The surface is matte and soft to the touch. Unlike the stiff primaries, body contour feathers like this are flexible and have a silky texture to provide both waterproofing and warmth.
Description
A small, colorful falcon about the size of a Mourning Dove. Males exhibit blue-grey wings, while females (and the back of both sexes) are primarily rufous with black barring. They possess a distinctive double 'mustache' mark on the face.
Key Features
The combination of the rich rufous-cinnamon color and a single, bold black spot near the rounded tip is a diagnostic hallmark of the Kestrel's mantle plumage.
Habitat
Open country, grasslands, meadows, deserts, and parklands. They are frequently seen perched on telephone wires or hovering over fields near highways.
Geographic Range
Extensive range across most of North and South America. Residents in the mid-latitude US; northern populations in Canada and Alaska migrate south for the winter.
Condition Notes
Good to Fair. The feather appears somewhat ruffled, likely a naturally molted specimen. There is some separation of the barbs (venting) along the left margin.
Interesting Facts
American Kestrels are one of the few raptors capable of seeing ultraviolet light, which allows them to track the urine trails of voles and mice on the ground.
Ecological Role
A key secondary predator in open ecosystems, controlling populations of large insects, lizards, and small rodents. They are cavity nesters, often utilizing old woodpecker holes.
Similar Species
Eurasian Kestrel (slightly larger, different barring), Merlin (darker, lacks the bright rufous on the back), and American Robin (similar orange tones but lacks the black falconiform spotting).
