Description

This feather represents the strength of the Red-tailed Hawk, a classic North American raptor with broad, rounded wings and a short, wide tail. Adults are famous for their namesake brick-red tails, while juveniles (implied by the heavy banding on this primary) have brown-banded tails. They are often seen soaring in thermals or perched on utility poles.

Colour & Pattern

Distal tip is solid dark chocolate-brown (melanic); transitioning into a series of 8-10 distinct dark brown transverse bars against a creamy white to pale buff background. The underside is notably paler with less distinct banding.

Barb Structure

The distal portion is tightly interlocked and pennaceous for aerodynamics; the proximal base shows soft, plumulaceous (downy) barbs for insulation. Barbules are intact with high structural integrity.

Texture & Surface

Smooth, stiff, and somewhat glossy on the upper surface. The leading edge feels particularly rigid and sharp, specialized for cutting through air during flight.

Key Features

High asymmetry of the vanes, distinct dark subterminal banding, and a yellowish-white rachis. The lack of white 'windows' or spotting distinguishes it from a Red-shouldered Hawk.

Habitat

Extremely versatile: found in open grasslands, agricultural fields, deciduous and coniferous woodlands, deserts, and increasingly in urban parks and highways.

Geographic Range

Ubiquitous across North America, from central Alaska and Canada south through Mexico and Central America to the West Indies.

Ecological Role

Apex predator primarily feeding on small mammals (voles, mice, rabbits) and reptiles; plays a critical role in controlling rodent populations.

Similar Species

Red-shouldered Hawk (shorter, thinner bands, typically blacker); Ferruginous Hawk (usually paler with more extensive white); Great Horned Owl (softer texture with 'comb' edges and different mottling).

Interesting Facts

The piercing 'kree-eee-ar' scream of the Red-tailed Hawk is so iconic that Hollywood almost always uses its recording for scenes featuring Bald Eagles, which actually have a much weaker, chirping call.

Condition Notes

Good to Excellent. The tip shows minor fraying from use (weathering), but there are no prominent fault bars (malnutrition lines) or parasitic holes. It appears to be a naturally molted feather.
