Чёрный бубу Laniarius fuelleborni

Mid-sized bushshrike that is completely black. Found in the undergrowth of humid forest at middle and high elevations. A skilled skulker that is most often detected by voice. Gives a wide variety of vocalizations, which include whistles, explosive notes, frog-like calls, and ratchets. The most common vocalization is a quick series of three whistles: “whit-whit-wee.” Very similar to Slate-colored Boubou, but found in montane forest rather than lower-elevation savanna and woodland.
