In some cultures bird saliva is considered a delicacy.
Indonesians have an interesting gourmet dinner of dead bats, some people from Laos import live snakes for a feast. A Corbra or other big snake is gathered from the rice fields in Asia, somehow get past the inspectors.
I asked a man from that area how they kill a dangerous snake. He said they grab it by the tail and whip it about to break his neck. Just crack it like a whip.
I don't know if this man was pulling my leg so anyone here on CC that served in Asia, can either confirm or say Bull Shit to the story.
