A guide to the barred flight feathers and large size of this African forest raptor, found in both a pied and a rare all-dark morph.

What Black Sparrowhawk Feathers Look Like
This is the largest sparrowhawk in Africa, and its size is one of the best clues in hand: female wing chords can exceed 30 cm, well above most other African accipiters. Most individuals are the pied ("light") morph, with glossy black upperpart feathers (crown, back, wings) and white underpart feathers marked with black barring or spotting, especially on the flanks and thighs. A rarer dark morph is almost entirely sooty black overall. Flight feathers show the classic accipiter (forest hawk) pattern: broad, rounded tips with strong dark barring alternating on a paler gray-brown background, typical of a bird built for quick maneuvering through trees. Tail feathers are long and boldly banded, matching the wing pattern.
Step-by-Step: Is This Feather From a Black Sparrowhawk?
- Measure it. A large, broad, rounded-tipped flight feather with a wing chord approaching or exceeding 25-30 cm strongly suggests this species over the smaller African accipiters.
- Check the barring pattern. Strong, well-defined dark bands on a paler brown-gray background, spaced fairly widely, matches this species' flight and tail feathers.
- Look at underparts. White feathers with black spotting concentrated on the flanks and thighs point to the common pied morph.
- Consider an all-black feather. If the feather is uniformly sooty black but has the broad, rounded accipiter shape (not a slender falcon shape or angular kite shape), the rare dark morph is possible.
- Assess overall wing shape. Broad, rounded wingtips and a long tail fit accipiter structure, ruling out kites and buzzards with more pointed or angular wings.
Similar Species & How to Tell Them Apart
African Goshawk is a similar forest-dwelling accipiter but noticeably smaller with finer, more closely spaced barring on its flight feathers. Other African accipiters in the same forests are all considerably smaller, so size alone rules most of them out. A dark-morph feather could superficially resemble a black kite or other dark raptor, but kites have more angular, pointed wings, while this species retains the broad, rounded accipiter wing shape even in its dark form.
Where & When You'll Find Them
Black Sparrowhawks live in forest and forest-edge habitat across sub-Saharan Africa, hunting from cover for birds and small mammals, and they are largely resident within their range. Feathers are most often found near nest sites in tall forest trees and along forest-edge hunting perches. Molt timing follows the breeding season, which varies by region — in southern Africa this generally falls in the austral spring and summer, so feather finds are more common in the months following local breeding.
Frequently asked questions
Why does the feather look mostly black with white barred underparts?
That matches the common pied morph of Black Sparrowhawk, with glossy black upperparts and white underparts marked with black barring on the flanks and thighs.
Could this be from the dark morph?
Yes, if the feather is uniformly sooty black but has a broad, rounded accipiter wing shape rather than the more angular shape of a kite or buzzard.
How is this different from an African Goshawk feather?
African Goshawk is noticeably smaller with finer, more closely spaced barring, while Black Sparrowhawk feathers are larger with bolder, wider-spaced bands.
Why is size such an important clue here?
Black Sparrowhawk is the largest sparrowhawk in Africa, so a large accipiter-shaped feather points strongly toward this species over the smaller African accipiters.
When are feathers most likely to be found?
Near nest sites and forest-edge hunting perches, especially in the months following the local breeding season.
