A "ghost hawk bird" is a common, evocative name for the American Goshawk (Accipiter gentilis atricapillus), a formidable and elusive raptor found in the dense, mature forests of North America. Its "ghostly" moniker stems from its remarkable ability to navigate through thick woodlands with incredible speed and agility, often appearing and disappearing like a phantom, making it notoriously difficult to observe.
Description and Identification
The American Goshawk is a large and powerful member of the Accipiter genus, known for its distinct features:
- Size and Build: They are among the largest of the accipiters, possessing a robust and bulky body.
- Wings and Tail: American Goshawks feature broad, rounded wings and a relatively long tail. A key identification feature in flight is their relatively long secondary flight feathers, which give the trailing edge of their wings a curved or bulging appearance. Their wingtips can also look pointed when in motion.
- Plumage: Adults typically have a slate-gray or blue-gray back and head, with a dark cap and a pronounced white stripe above their piercing red eyes. Their undersides are often finely barred with white and gray. Juveniles are streaky brown with yellow eyes.
- Flight: They are powerful, agile fliers, capable of sudden bursts of speed and sharp turns, perfectly adapted for hunting within cluttered forest environments.
Habitat and Range
American Goshawks prefer extensive tracts of mature and old-growth forests, particularly those with dense canopies and an open understory. These habitats provide ample cover for hunting and nesting. While most commonly associated with coniferous and mixed forests, they can also be found in deciduous woodlands. Their range extends across much of North America, including parts of Alaska, Canada, and the western and northern United States.
Hunting and Diet
Known for their ferocity and hunting prowess, American Goshawks are opportunistic predators. They primarily prey on medium-sized birds and mammals, often ambushing their victims from concealed perches or pursuing them through the trees.
Common Prey Includes:
- Birds: Crows, jays, grouse, pheasants, woodpeckers, and various songbirds.
- Mammals: Squirrels, rabbits, hares, chipmunks, and even smaller rodents.
Their powerful talons and sharp beaks are perfectly adapted for subduing prey, and their stealthy approach makes them incredibly effective hunters.

Conservation Status
American Goshawks are sensitive to habitat disturbance and fragmentation. Their reliance on mature forest ecosystems makes them vulnerable to deforestation and unsustainable forestry practices. Conservation efforts often focus on protecting large blocks of their preferred habitat and minimizing human disturbance in nesting areas.
