I was guessing it was M-S, possibly a 30 and a 60. The bullfrog that
starts at 29 seconds seems like its on a different spatial plane from
the other sound sources. (I think the same individual is also singing
during the initial fade in). Even if other calls are from behind the
mics, all of the other calls seem located in the "front" of the
stereo field to me. Perhaps the discrepant bullfrog's calls are
reflected within the space differently. I'm trying to gather clues
about how this effect is produced.

That would be interesting to try. Your mix is very pleasant as is.
Thanks for the additional info! Rob D.
