Description

This feather comes from a Cooper's Hawk, a crow-sized woodland raptor known for its long tail and rounded wings. The bird itself has a blue-gray back (in adults) and a reddish-barred breast. Juveniles, which likely produced this feather, are brown above with vertical brown streaks on a white chest. They are master flyers, weaving through dense canopy to hunt smaller birds.

Colour & Pattern

Base color is off-white to cream. It features distinct transverse brownish-gray bands or "bars." The tip is colored with a darker terminal band. The ventral side is noticeably paler and more matte.

Barb Structure

Pennaceous at the distal end with interlocked barbules; transitioning to plumulaceous (fluffy) at the base near the calamus.

Texture & Surface

Soft and silky to the touch, with a somewhat matte surface. The pennaceous portion is smooth but not highly glossy, typical of woodland raptors.

Key Features

Distinctive brownish-gray horizontal banding on a light background; rounded tip; downy basal section; size appropriate for a medium-sized Accipiter.

Habitat

Mixed woodlands, deciduous forests, and increasingly common in suburban backyards where bird feeders attract smaller prey birds.

Geographic Range

Year-round resident across much of the United States and southern Canada; northern populations migrate to the southern U.S. and Central America for winter.

Ecological Role

Apex predator of small to medium birds and mammals; helps maintain healthy populations of songbirds and rodents. Currently stable population.

Similar Species

Sharp-shinned Hawk (feathers are smaller and bands often more reddish-brown) and Red-shouldered Hawk (which typically has more stark, high-contrast black and white banding).

Interesting Facts

Cooper's Hawks are often called 'true hawks' or 'accipiters.' They have a specialized hunting style called 'still-hunting' where they wait in dense cover then burst out in a high-speed chase.

Condition Notes

Good condition; the barbs are mostly intact, suggesting the feather was naturally molted recently rather than damaged by a predator. Minimal wear at the tip.
