Similes and metaphors, based on the symbolic of the natatorial birds, such as the swan, the goose, the scaup duck, the green-winged teal, the oldsquaw - long-tailed duck, appear across the genres of the verbal description in oral rune-poems in the Kalevala meter. The ethnopoetical constansts, dealing with the aquatic sphere of the ornithological symbolic, correspond with the ornithic characters of the swan and the scaup, involved in the mythic plots of the Kalevalaic rune-poems and there in the laments appear systematic correspondences.
