Alkonost in Slavic mythology is a wonderful bird, a resident of Iria - Old Slavic paradise.
Lick her female body as a bird, and a voice sweet as love itself. Alcon heard singing for joy can forget everything, but the evil of her people do not, in contrast to her friend's bird Sirin. Alkonost lays eggs "on the edge of the sea", but incubates them, and plunges into the depths of the sea. In this time of seven days is windless weather - until the chicks hatch.
