whistling-jar

from The Century Dictionary.

• noun A peculiar kind of jar made by the ancient Peruvians, particularly in the region of Chimu, provided with double or connecting spouts through which the air rushes when the contents of the jar are poured out. By appropriate constrictions in the spouts the inrushing air is made to produce a whistling sound. Sometimes these jars have the forms of animals and the sound is intended to imitate the voice of the animal.
