The aviaries and pterosaurs are very awesome, but the animals seem to spend 90% of their time on the ground sitting on the viewing galleries, with the rest either on the ground or the fish feeder. It's a bummer that they don't perch atop the rock decorations, but understandable since you can rotate them every which way and coding the specific spots would be a pain. Having natural or artificial rock formations and platforms that you can place in the aviaries would be excellent, both free-standing and ones attached to the sides of the aviary, like how the RtJP Aviary was set up, that way our flying friends can have more high places to perch and lord over their domain.
