Description
A medium-sized forest hawk with broad, rounded wings and a long, rounded tail. Adults feature dark slate-gray upperparts and distinctive rufous-and-white barred underparts. Known for its incredible agility and high-speed navigation through dense forest canopies while hunting birds and small mammals.
Colour & Pattern
Pale bluish-gray or silvery-gray background crossed by several bold, dark charcoal-black transverse bands (bars) with a distinct white tip
Barb Structure
Tightly interlocked pennaceous barbs forming a smooth, firm vane with strong barbicels, and some plumulaceous fluff at the extreme base near the calamus
Texture & Surface
Stiff, smooth, and matte with a firm rigidity providing aerodynamic stability during flight and sharp turns
Key Features
Bold dark and light gray alternating bands with a distinct white terminal tip, characteristic of adult Cooper's Hawk tail feathers
Habitat
Deciduous and mixed forests, open woodlands, wooded suburbs, forest edges, and river groves
Geographic Range
Year-round resident across most of the United States, southern Canada, and parts of Mexico, with northern populations wintering further south
Ecological Role
Apex avian predator that helps regulate populations of songbirds, doves, and small mammals, serving as an important indicator of forest ecosystem health
Similar Species
Sharp-shinned Hawk and Northern Goshawk; Sharp-shinned tail feathers are smaller with square-tipped ends, while Goshawk tail feathers are significantly larger
Interesting Facts
Cooper's Hawks are master acrobats, capable of high-speed pursuits through thick brush, sometimes sustaining impact forces by using their long tails as rudders and brakes
Condition Notes
Good condition with intact barbs and only minor fraying at the base, showing normal wear for a naturally molted feather
