Sorry for the late response, but no it's not standing. I believe it was either located in an area that was part of the zoo before the Quinta da Boa Vista got smaller (it shrunk its size a lot since the video was recorded) or in the area between the former feline/primate enclosures and the deer park (now called Aventura Selvagem).
Oh yes. I already suspected that were it's located the Evaristo de Morais Jail and other areas was once part of the zoo. It's a shame that it got smaller, but hopefully the grupo Cataratas plans will be enough to use the available space properly.
