There are five aviaries at the Indianapolis Zoo and we hit all five of them. Two of the aviaries are walk-throughs; while leaving one of those we watched two birds escape into the airlock. We waited about 15 minutes before the Zoo staff could coax them back into the main section. I spent that time gathering more pictures. Those birds are quick! Aviaries usually allow for close-up shots of the birds so I spent a lot of time around these lorikeets.
