That looks pretty good. I have seen thick-billed parrots at 5 zoos (2 in Arizona and 3 in So California) and none of them have very good exhibits and I have yet to get a decent photo of this species.
The Cincinnati Zoo has two exhibits for this species. One is within the Wings of the World building and another in Wolf Woods, both of which allow for unobstructed viewing. The exhibit in Wings of the World uses the dark hallway / lit exhibit method to keep the parrots, and quails, in. Only a small ledges seperates the visitors from the birds. The exhibit in Wolf Woods is a walk-in aviary with the same mix of parrots and quails.
When Grizzly Ridge opened in 2013, this exhibit (formerly wild turkey) became home to snowy owls. The exhibit next to it near the cafe is burrowing owls, and across the way near the restrooms is an empty dome exhibit, for prairie dogs, rabbits, and then tortoises. I enjoy the theme of Wild Prairie, but it was much larger before 2012- with coatimundis where Monkey Island was, tortoises, waterfowl, eagles, and otters.
