Actually, now that I look at that last page from the sanctuary again, it doesn't actually say that the owl in the picture identified as the Southern variety is Popo-chan, I just jumped to that conclusion. What's more, looking at the google translated version of the main page, near the top there's a section that says "Here are the highlights", and one line in that section is translated by google (a better translation would be helpful) as "intimidation, famous in Japan in the mimicry Owl Giant African Scops of Popo Chan". The link for "Giant African Scops" gives the scientific name as Ptilopsis leucotis which refers to the Northern White-faced Owl, not the Southern, and since this link is right next to the link for Popo-chan, I assume that link must be intended to tell readers what kind of owl Popo-chan is. So, I think I'll have to move this info back to the Northern White-faced Owl after all.
