American Kestrel (formerly Sparrow Hawk)

This is a primary wing feather from North America's smallest falcon. The American Kestrel is a colorful raptor, with males having blue-gray wings and females being rufous and barred. This specific feather, with its slate-gray tone and white spotting, likely belongs to a male.

Dark slate-gray to blackish-brown ground color with distinct, bold white oval spots (windows) on the inner vane; typical of a male American Kestrel's wing pattern.

Tightly interlocked pennaceous barbs providing a rigid, aerodynamic surface; few plumulaceous (downy) barbs at the very base of the calamus.

Smooth, stiff, and somewhat glossy on the dorsal surface; designed for high-speed flight and durability against wind resistance.

Sharp asymmetry, dark gray-black coloration with distinct white oval translucent-looking spots on the inner vane, and a pointed tip.

Open country, grasslands, meadows, deserts, and parklands; often seen perched on telephone wires or hovering over fields.

Widespread throughout North and South America; northern populations are migratory, while southern populations remain resident year-round.

A vital secondary consumer that controls populations of insects, small rodents, and occasionally small birds; they are cavity nesters.

Merlin (Falco columbarius) feathers are similar but generally lack the clean, bold white oval spotting and tend to be darker/streakier.

Kestrels have the ability to see ultraviolet light, which allows them to track the urine trails of voles and other rodents on the ground from high above.

Good to Excellent; the vanes are largely intact with minor fraying at the trailing edge, suggesting it was molted recently or is a fresh specimen.
