Cooper’s Hawk
Accipiter cooperii
A feathered missile designed for one purpose: catching birds in flight. The Cooper’s Hawk is the American accipiter of choice—fast, intense, and demanding of skill.
The Accipiter Experience
Accipiters are a different animal entirely from the buteos most falconers start with. Where a Red-tail is a patient soaring hunter, the Cooper’s Hawk is an explosive sprinter—built for short, violent pursuits through trees and brush.
Flying a Cooper’s Hawk is often described as “holding a live wire.” They’re intense, reactive, and utterly committed to the chase. This makes them thrilling to fly but unforgiving of mistakes.
Cooper’s Hawks have been flown in North American falconry for decades, though they were long overshadowed by the Eurasian Goshawk and European Sparrowhawk in the global accipiter tradition. American falconers gradually recognized that the Cooper’s Hawk offers a distinctly rewarding experience—combining the explosive speed of accipiters with a size manageable enough for suburban bird hawking. The species gained serious momentum in the 1990s as more General-class falconers sought the thrill of accipiter flights. Today, Cooper’s Hawks have a dedicated following among falconers who prize the intensity and challenge of pursuing fast-flying bird quarry.
Why Not for Beginners
Cooper’s Hawks have high metabolisms, narrow weight windows, and nervous temperaments. A mistake that a Red-tail would shrug off could kill a Cooper’s or ruin months of training. Most falconers recommend 3-5 years of experience with other species first.
Hunting Style
Cooper’s Hawks are bird specialists. Their primary quarry includes:
- Starlings — Classic accipiter quarry; abundant and fast
- Sparrows and finches — Especially for smaller males
- Doves and pigeons — Larger females can handle these
- Quail — Where legally available, excellent quarry
- Robins and jays — Common yard birds make good practice
The hunt is typically a short, explosive affair. The hawk launches from the fist or a nearby perch, accelerates through cover, and either connects in seconds or misses entirely. There’s little soaring or waiting involved.
Hunting with a Cooper’s Hawk is a study in controlled chaos. The falconer typically walks through suburban neighborhoods, parks, or farmsteads where starlings, sparrows, and pigeons gather. The hawk rides the fist, coiled with tension, scanning every bush and roofline. When quarry is spotted, the release is instantaneous—the hawk explodes from the glove in a blur of wings, threading through obstacles at bewildering speed. Flights last seconds, ending in either a dramatic catch or an empty-footed pull-up. The falconer must then quickly locate the bird, make in if successful, or recast for another slip. It is exhausting, exhilarating, and utterly addictive.
Temperament
“Hot” is the word most often used. Cooper’s Hawks are alert, reactive, and easily stressed. They don’t tolerate handling mistakes well, and they’ll let you know immediately when something’s wrong.
However, a well-manned Cooper’s Hawk from an experienced falconer can be surprisingly tractable. The key is consistent, calm handling from day one—and knowing when to give them space.
Temperament Spectrum
Individual variation exists, but most Cooper’s run hot. Passage birds (wild-caught in their first year) tend to calm down more than eyasses (raised from chicks).
Training Considerations
Training a Cooper’s Hawk requires patience and precision:
- Narrow weight window: Often just 10-20 grams separates too high from too low
- Fast metabolism: They need to eat daily; skipping a day is risky
- Quiet manning: Avoid loud noises, sudden movements, and chaotic environments
- Short sessions: Multiple brief training sessions beat one long one
- Consistent routine: They do best with predictable handling patterns
Housing Requirements
Accipiters are notoriously hard on their feathers and feet. Housing must be carefully designed:
- Padded perches: Essential to prevent foot problems
- Smooth walls: No rough surfaces to damage feathers
- Bath pan: Daily access to water; they love to bathe
- Visual barriers: Solid walls or screening to prevent bating at stimuli
- Appropriate size: Large enough to move but not so large they hit walls
Cooper’s Hawk care demands a disciplined daily rhythm. The morning weigh-in is critical—these accipiters have narrow weight windows, and even ten grams can separate an eager hunter from a sulky perch-sitter. Housing must be checked daily for damaged feathers against walls and for signs of bumblefoot on perches. Fresh water for bathing is essential, as Cooper’s Hawks are avid bathers. Feeding is carefully portioned, often consisting of starling, quail, or day-old chick, with amounts adjusted daily based on weight trends and upcoming activity. The falconer must maintain a calm, predictable routine—these sensitive accipiters respond poorly to disruption.
Is a Cooper’s Hawk Right for You?
Consider a Cooper’s If:
- You have 3+ years of falconry experience
- You’re fascinated by bird-hawking specifically
- You can commit to daily attention and precise weight management
- You have access to good starling or sparrow habitat
- You enjoy the intensity and challenge
Look Elsewhere If:
- You’re still an apprentice or new General falconer
- You want a laid-back, forgiving bird
- Your schedule doesn’t allow daily attention
- You primarily want to hunt rabbits or squirrels
- You get frustrated easily
The Reward
For the right falconer, a well-trained Cooper’s Hawk is pure magic. Watching your bird thread through trees at impossible speeds, snatch a starling from mid-air, and return to your fist with that fierce, wild look in her eyes—it’s unlike anything else in falconry.
The intensity that makes them challenging is the same intensity that makes them thrilling. If you’re drawn to that fire, and you’re willing to put in the work to match it, the Cooper’s Hawk may be your bird.
learnSpecies.coopersHawk.fieldIdentificationTitle
Cooper’s Hawks are medium-sized accipiters with rounded wings, a long banded tail, and a distinctive flat-topped head that distinguishes them from the similar Sharp-shinned Hawk. Adults display blue-gray upperparts with rufous barring on the chest, while juveniles show brown upperparts with vertical breast streaking. In flight, Cooper’s Hawks exhibit a characteristic flap-flap-glide pattern and a proportionally larger head that projects well beyond the wings. The tail appears rounded at the tip rather than square, and the bird’s overall impression is of a powerful, agile predator built for explosive acceleration through dense cover.

Cooper’s Hawks have made a remarkable population recovery since the DDT era, when pesticide contamination caused widespread reproductive failure among raptors. Today they are classified as Least Concern by the IUCN and their populations are stable to increasing across most of North America. They have adapted successfully to suburban and urban environments, where backyard bird feeders provide concentrated prey resources. This adaptability has made them one of the most commonly encountered accipiters in residential areas, though their predation on songbirds occasionally generates conflict with birdwatchers.
learnSpecies.coopersHawk.historicalUseTitle
Cooper’s Hawks were historically considered difficult falconry birds due to their nervous temperament and tendency toward aggression during training. However, a dedicated community of accipiter specialists has developed refined training methods that make Cooper’s Hawks viable and exciting hunting partners for experienced falconers. They excel at pursuing birds in dense cover, delivering explosive flights that few other species can match. In medieval European falconry, the closely related European Sparrowhawk filled a similar niche, and the techniques developed for that species have been adapted for Cooper’s Hawk falconry in North America.
