Guacharaca

It is a rasp named after a bird (ortalis guttata) whose call it is said to imitate.

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.

It is played with a fork composed of hard wire fixed into a wooden handle.

The guacharaquero (guacharaca player) scrapes the fork along the instrument's surface to create its characteristic scratching sound.

The guacharaca was invented by native American Indians from the Tairona culture in the region of la Sierra Nevada de Santa Marta, Colombia as an instrument to simulate the guacharaca (or Ortalis ruficauda) bird's singing.
