Red-tailed Hawk

Kingdom: Animalia, Phylum: Chordata, Class: Aves, Order: Accipitriformes, Family: Accipitridae, Genus: Buteo, Species: Buteo jamaicensis

Family: Accipitridae (Hawks and Eagles)

Shape
Broad and slightly asymmetrical with a rounded, blunt tip. The trailing edge is curved while the leading edge is straighter, typical of a secondary feather that provides lift.
Size
Estimated 7–9 inches (18–23 cm) in length. This is consistent with the secondary feathers of a large Buteo hawk, which are notably shorter and broader than the primary flight feathers.
Rarity
Common. The Red-tailed Hawk is the most widespread and frequently seen Buteo in North America.

Description

This feather represents the classic 'mottled' look of a Buteo hawk's wing. The Red-tailed Hawk is a large, bulky raptor with a 4-foot wingspan, known for its iconic cinnamon-red tail (in adults) and dark 'patagial' marks on the leading edge of the wing.

Colour & Pattern

Dusky dark brown distal (outer) half with a solid tip. The proximal (inner) half features distinct white and brown mottled banding/barring. The ventral side is significantly paler with muted versions of the dorsal patterns.

Barb Structure

Mostly pennaceous, with tightly interlocked barbs creating a firm, wind-resistant vane. The base shows a small amount of plumulaceous (fluffy) down for insulation.

Texture & Surface

The dorsal surface is semi-glossy and smooth to the touch, designed for aerodynamic efficiency. The feather feels stiff and resilient, characteristic of a large raptor species.

Key Features

Bold dark brown tip, distinct horizontal barring on the inner vane, and a robust white rachis at the base. The width-to-length ratio is much higher than that of a primary feather.

Habitat

Extremely versatile; found in open woodlands, prairies, agricultural fields, deserts, and urban parks containing tall trees or utility poles for nesting and perching.

Geographic Range

Year-round resident across most of North America, from central Alaska and Canada south through Mexico and Central America. Northernmost populations are migratory.

Ecological Role

Apex predator. They play a vital role in controlling populations of small mammals, reptiles, and occasionally other birds.

Similar Species

Red-shouldered Hawk (smaller, more distinct white/black banding), Cooper's Hawk (narrower, more uniform grey/brown banding), and Broad-winged Hawk (fewer, wider bands).

Interesting Facts

The scream of the Red-tailed Hawk is so iconic and piercing that Hollywood sound editors almost always use it for any hawk or eagle shown on screen, including the Bald Eagle.

Condition Notes

Good condition. There is minor fraying at the tip and along the outer margin, suggesting it may have been molted naturally at the end of a breeding season.
