These are Aeta performers (top) doing their native war dance with their hunting bows and arrows. Usually meant for hunting small animals, these weapons are nevertheless effective and dangerous. Here, they are merely props for a cultural presentation meant for entertainment.
After the eruption of Mt. Pinatubo, many Aetas were displaced from where they used to live away from the cities and the old way of life that they've known for so long suddenly vanished. Gone are the old days when they're ancestors lived at peace in the forests. These days, they're now part of mainstream society and work for a living just like other Filipinos.
