Australian Aborigines use "emu callers" to attract emus.
The sound is made by tapping one end with the hand. This creates a sound that gets the interest of an emu and lures it from its nest so that the emu eggs can be safely removed by the egg hunter. An emu caller is created the same way as a didgeridoo, using branches of gum tree which have been hollowed out by termites.
This one goes beyond mere painted decoration with the artist incizing designs into the soft wood.
