Secondary flight feather (Remex)

Red-tailed Hawk

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

Family: Accipitridae (Hawks, Eagles, and Kites)

Shape
Broad and somewhat symmetrical compared to primaries, with a rounded tip; the inner vane is wider than the outer vane, giving it a slightly curved, paddle-like outline.
Size
Estimated 7-9 inches (18-23 cm) in length. This is consistent with the secondary feathers of an adult or sub-adult Red-tailed Hawk, which typically range from 6 to 10 inches depending on position.
Rarity
Very Common. One of the most widespread and frequently seen raptors in North America.

Description

This feather represents the classic 'Eastern' or 'Borealis' morph of the Red-tailed Hawk. The bird itself is a large, bulky raptor with a 4-foot wingspan, known for its iconic rufous-red upper tail in adults and its high-pitched, screaming 'kee-ee-ar' call used in Hollywood movies.

Colour & Pattern

Distinctive 'marbled' or 'banded' pattern. The outer web is dark chocolate brown. The inner web is creamy white with bold, dark brown transverse bars that do not fully reach the rachis. The tip is solid dark brown.

Barb Structure

The distal portion is pennaceous with tightly interlocked barbs for flight stability, while the proximal base (near the calamus) features loose, plumulaceous barbs for insulation. Barbules are intact with minimal fraying.

Texture & Surface

The surface is smooth and stiff to the touch with a slight matte finish. The dorsal side is more richly colored, while the ventral side (underneath) appears more silvery and dull.

Key Features

White inner vane with dark, incomplete banding; thick white rachis; broad secondary shape; chocolate brown distal tip.

Habitat

Extremely versatile: found in open woodlands, agricultural fields, prairies, deserts, and increasingly in urban and suburban parklands.

Geographic Range

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

Ecological Role

Apex predator. Plays a vital role in controlling rodent and rabbit populations. They are ecological indicators of habitat health in fragmented landscapes.

Similar Species

Red-shouldered Hawk (smaller, more frequent/regular banding), Broad-winged Hawk (fewer, thicker bands), or Red-tailed Hawk 'Harlan's' morph (more mottled/grayish).

Interesting Facts

The 'scream' of the Red-tailed Hawk is so impressive that it is almost always used as the sound effect for Bald Eagles in television and film, as real eagles have much chirpier, weaker calls.

Condition Notes

Excellent condition. The edges are crisp with no obvious 'fault bars' (stress lines) or parasitic holes. It appears to be a naturally molted feather rather than one lost to trauma.
