Sowparnika is a river descend from Kodachadri hills. Legend says
that Suparna (Garuda) did a penance on the banks of this river
praying to the Goddess for the abatement of his mother Vinutha's
sorrows. When the Goddess appeared before him, he prayed that the
river be henceforth known after him, Suparna, and therefore came to
be called as Sowparnika. Thanks, nvkmr@msn.com
