When I first visited, back in 2010, I was on crutches and my mobility was very limited. I wasn't able to make it into the building but I assumed this building at the end of a cul-de-sac of parrot aviaries was for more parrots, but last year I discovered that this is where a group of Andean (Peruvian) cocks-of-the-rock are kept. They also displayed a grison and an anaconda (all in separate enclosures).
