According to Bulgarian tradition in Macedonia, the Navi and Navjaci are invisible genii soaring in the depths of the firmament, appearing in the shape of birds, and crying like infants. They are the souls of children who have died un-baptized, and in their search for their mothers they attack and trouble women in childbed. They may be set free, however, if the baptismal formula is said over them. The Slovenian Navje, in like manner, are believed to fly about in the form of huge, black birds, who plead to be baptized. If any one is moved to pity by their wailing and baptizes them, he will be their great benefactor; but if he ridicules them or whistles at them, he will rouse their anger.

The Rusalky live in woods, meadows, fields, and waters. Generally appearing when the corn begins to ripen in the fields, and concealed amidst it, ready to punish him who wantonly plucks the ears, they dance and make merry, adorned with the many-coloured blossoms of the poppy and
