The chest extender device is designed to attract exotic birds. Naila eggs are laid through the head of the bird, so the goal is to collect the egg for the all-important potion of Dinwa, the essence of the DOL hallucinogenic ceremonies.
Chilabongs are worn by Carnival dancers. Naila birds are attracted to the bright color of the Chilabong. As they are flying downwards, their eggs fall from their heads and the dancers must position their Chilabongs in such a way as to catch the eggs without breaking them. The “harvested” eggs are then delivered to Dinwa distillers.
