Extraordinary short-tailed swift with weak, fluttery, bat-like flight. Note the pale underparts and white rump patch. Seen on the wing over woodland, gallery forest, and moist savannah, especially miombo. Often in areas with baobabs, which are favored nesting sites. Usually solo or in pairs. Range does not overlap with that of the similar Sabine’s Spinetail. All other swifts have a longer tail.
