I can see this working across the zoo, It is viable in all walk through aviaries bar 1: Monsoon Forest, at the exits sure but where would the first of these be for the entrance? Right by the Hornbills, or past Tripa research centre where the actual walk through aviary starts I'm confused on the logistics of this method in Islands, but everywhere else you can walk in with the birds I can see it working I'm just confused with MF as it is split into two, so where would the first of these go... Otherwise I am just looking to much into the situation haha.
