Because the Trumpet Manucode is highly territorial, its voice has to travel far. “Its calls are strong, deep, and impossible to ignore—used to claim space or call to its mate. One description of the male’s song mentions a trembling, resonant fluttering sound performed with raised feathers and outstretched wings. Other call notes include kauaugh (like a raspy cough), kowp, or kyawk. In the highlands, observers have even heard duets between males and females!’
