If Oryoki says they are spectacular, then they probably are. Sounds like
Oade aren't great at providing the most flattering samplings...but we have
had reports over the last year from this group, that confirm what she says.
One such report was from Raphael Marquez and he was kind enough to provide
his own samples. http://www.fonozoo.comeng/rinconbioacustio.php
