Bayok is one of the traditional medium of communication that still exists and is used by the Mandaya’s of Davao Oriental. It is a communication tool to settle disputes, to formally declare one’s intention to marry, to relate significant events and experiences, and to express one’s happiness for good fortune. To a great extent, Bayok communicated El Niño and its disastrous effects in the region. The Mandaya’s belong to a group of indigenous people mostly living in the hinterlands of Davao Oriental in Region XI. Their population is estimated at 300,000—roughly 68% of the total population in the eleven municipalities of Davao Oriental.
