 Linguistic work among the Urarina was first pioneered by SIL International.The Urarina have a deluge-myth, in which a man saved himself from the deluge while climbing a cudí (amasiza, Erythrina elei) tree; the man's wife was transformed into a termites' nest clinging to that tree, while their two sons became birds.Afterwards that man acquired a wife, a different woman, one who had at first summoned successively a pit viper, a spider, and a giant biting ant in an unsuccessful attempt to evade him.
