Tracking Song names
According to a friend of mine who is a anthropologist, the "animal" names look "vaguely Algonkian, the languages which were spoken over much of the northeast (Micma, Abnaki, Massachusett, etc.)"
However, he can't be sure. Perhaps this can send someone in the right direction, either on the net or in a library.
