the guacharaca

is a musical instrument from scratch. It consists of two parts: the guacharaca itself, corrugated surface, and the comb or fork, made of stiff wire and wooden handle, used to scratch the surface of corrugated guacharaca.
This instrument was invented by Native American peoples of the Tayrona culture in the region of the Sierra Nevada de Santa Marta, Colombia, as a tool to mimic the birdsong guacharaca.
