Are you sure? According to the white upper head part, I would label it as a Amazon Skunk (Conepatus semistriatus).
However, a very rare specie in zoos.
Very nice indeed! However, I would concur with zoomaniac in saying this individual looks more like Amazonian Hog-nosed Skunk (Conepatus semistriatus).
This raises the possibility that the individuals held at Barcelona in c.2002 were also misidentified, if your theory that these were the same individuals as - or the parents of - this animal.
