Two lovers Kivigho and Kahuli were on their way to their native village. At a certain point, to get some fruit for his lady love, Kivigho climbed up a tree. But he could not climb down as the branches of the tree broke. Having been stuck there, slowly and gradually Kivigho turned into the Great Hornbill. A feather of the Hornbill fell on the lap of a heartbroken Kahuli. She treasured the feather for whole life in memory of her lost love, a Sumi Naga legend.
