I had a new idea for the Peccary/Owl/etc complex - 'Burrow Vision'.
Simply put - essentially somewhat what is done in several zoos' meerkat exhibits, and I think that this would give quite an interesting view-point from the visitors' perspective, and also may give the visitors a feeling that they are viewing the complex from the animals' point of view. This may also give rise to close viewing between animals and visitors, potentially allowing them to view peccaries/etc up close. It may even allow for a bit of an educational display here, with signage telling of the underground lifestyles of Burrowing Owls and Jackrabbits.
