Gosh, mostly wikipedia… I’ve seen a couple books on amazon, but its sort of a gamble…
Wiki’s been a bit of a dead end. But perhaps tomorrow I shall make a trip to the liiibrary~
I have a Field Guide to Imaginary Birds, but it doesn’t have much for the US. Books of early US ballads or poems might be easier to find.
Mm, good point. I might have to go down to the huge university library and see what turns up.
