They are almost entirely black with whitish patches on the sites of the forehead and the feathers on he belly have white edging.
Black Swifts spend most of their lifetime in the air as this is where they do most of their foraging. Their nesting sites include high altitude caves or enclosures near waterfalls or streams. They needs to nest in dark places as their nests cannot be exposed to sun.
