Blue jays are tricksters in lots of cultures. I pulled out the paper with the citation for a lot of material: see

Swanton, John R. Source Material for the Social and Ceremonial Life of the Choctaw Indians: Smithsonian Institution Bureau of American Ethnology, Bulletin 103. Washington: U.S. Government Printing Office, 1931.

There are several other sources, such as

Campbell, T.N. "The Choctaw Afterworld." Journal of American Folklore, 1959: 72:146-54.

The Campbell article is particularly concise. Swanton covers more of the origin stories, Campbell the eschatology.

I've read a fair amount about the Tewa culture in the context of American Indian literature. An observation (a la Joseph Campbell, who was on PBS in a Moyer replay today): many Euramericans within the framework of the Enlightenment (and beyond, up to today) looked at Indian origin stories and assumed they're just stories that people take lessons from, but they can't possibly be real. Then they forced their own Christian beliefs on those cultures because they take their own origin myths literally. Duh. No wonder other cultures learned to "signify," to bury their own sharp, witty meanings within their songs, in plain sight of the colonizers.

Okay, off my soapbox, now back to weaving and spinning.
