Guacharaca

Guacharaca [ɡwatʃaɾaˈka] is a percussion instrument found in Colombia. It is a rasp named after a bird (ortalis guttata) whose call it is said to imitate. It is usually made out of the cane-like trunk of a small palm tree. The guacharaca itself consists of a tube with ridges carved into its outer surface with part of its interior hollowed out, giving it the appearance of a tiny, notched canoe.
