Current-day Brazilian zoos have a long history with wolves:
Rio de Janeiro imported a gray wolf along with two European badgers in 1949. Then, in 1965, a pair of Canis lupus was brought from Los Angeles along with two American black bears. They lived into the 1970s, but I'm sure if they reached the 1980s.
São Paulo imported its first wolves (I believe timber wolves from Washington) in 1972. Then, in 1987, a pair was brought from Poland, and they gave birth to a pup around 1991. They sadly passed away during the 1990s. However, the zoo would give a last shot at keeping the species in 1997, when two pairs were brought from Canada, and a litter of three pups was born three years later.
There was also an "European wolf" in Recife in 1993, though I'm not sure about its origin. Maybe it was born to the original Paulista pair.
I need help identifying the porcupine species held in São Paulo from the 1970s to the 1990s. I'm not sure if they were
Hystrix africaeaustralis or
Hystrix cristata. The zoo was just lazy as labeled them as
Hystrix sp.
