Northern Goshawk

Northern Goshawk

The Northern Goshawk is the largest and most powerful of the accipiter hawks, a formidable forest predator found across the boreal and montane forests of North America, Europe, and Asia. Its fierce reputation and bold white eyebrow stripe over a piercing red-orange eye make it one of the more striking forest raptors.

Larger and broader-winged than its smaller relatives Cooper's and Sharp-shinned Hawk, the Goshawk still relies on the accipiter body plan of short bursts of powerful flight to pursue prey through dense mature forest.

Identifying Northern Goshawk Feathers

• Primaries/secondaries: broad and rounded, slate-grey above in adults (brown in juveniles), finely barred pale grey below, notably larger and broader than Cooper's Hawk flight feathers.
• Tail feathers: long, broad, with wavy or irregular dark bands rather than the crisp straight banding of smaller accipiters.
• Undertail covert feathers: fluffy, white, and often conspicuously puffed out, a feature the bird displays during territorial or courtship behavior.
• Body feathers: adults are pale grey finely barred below with a bold white supercilium (eyebrow) feather tract; juveniles are heavily streaked brown on buffy underparts.
• Overall large size combined with wavy tail banding and fluffy white undertail coverts distinguishes Goshawk feathers from the smaller, crisper-banded Cooper's and Sharp-shinned Hawks.

Plumage

Adults have slate-grey upperparts, a bold white stripe over a red-orange eye, and pale grey underparts with fine barring, plus fluffy white undertail coverts. Juveniles are brown above with heavy dark streaking on buffy underparts and a yellow eye, taking a couple of years to reach adult plumage. Females are considerably larger than males.

Habitat & Range

Found across boreal and montane coniferous and mixed forest of North America, Europe, and Asia, generally requiring extensive mature forest for breeding. Northern populations may move south in years of prey scarcity ('irruptions'), while many populations are largely resident.

Behavior & Field Notes

Northern Goshawks are powerful hunters of mid-sized birds and mammals, using fast, agile flight through forest to overtake prey, and are known for aggressively defending their nest sites against intruders, including humans. Nests are large stick platforms built high in mature forest trees, often reused for years. Calls include a loud, harsh 'kak-kak-kak' near the nest. A large, broad grey or brown-streaked feather with irregular tail banding found in mature forest is consistent with this powerful species.
