Hello,

I'm a french zookeeper and I'm working with Rhinos in Zoo de Lunaret, Montpellier...

I'm able to say that lacking black fringes on ears is absoluty not a mean to distinguish Southern WR from Northern WR.

Effectively, our young male, Jobi (who born at Suffolk Safari Park) has these black fringes on his ears, somethat longer that in Norther subspecies !!!
And one of our females, Mafunyane, has these black finges too, and she comes from South Africa...
