Walk-through tunnel Flamingo - Ibis - Macaw aviary

Why seperate visitors from ibis and macaws?

@DelacoursLangur With macaws I can actually understand why you wouldn't want them to get into contact with visitors. They basically have a machete attached to their face so you wouldn't want anyone to get bit.

I think this tunnel is a not entirely successful attempt at giving people a good view into an aviary without making it a walk-through.

@KevinB I guess, I have visited plenty of zoos with walkthrough macaws however. Seems a bit pointless if you ask me.
