At olden times in Kerala, India, the people were divided into different castes (according to the work they did). A Pulluvan is a male member (female Pulluvatti ) of low caste group called Pulluvar. The term pullu means a bird of omen. The term pulluvan must have meant ‘a person who predicts from the sound of birds’. There are many sub-divisions within the Pulluva community. The majority among them are called Nagampatikal (People who sing snake-songs).
