One day, while most of the men were working in the fields nearby, the housewives started noticing that several infants had disappeared in the community. Neighbors became concerned about the small children, for mothers could not look after their children all the time due to their housekeeping duties; finally, the whole community realized that giant birds called "Tiw" were responsible for several missing children in the community, and assumed that these predators had taken the little ones to their nests for food. The elders devised a mechanism to protect infants from birds: they would cover their heads with a basket, yet when one neglected to cover the infants, they were still being taken away by the giant birds.
