Did you see any macaws in here? The unique shape of the structure is already neat, but this might also be the only real walkthrough aviary with free-flight macaws in the country as far as I'm aware.
@pachyderm pro I saw two macaws, and they were incredibly loud, making a big racket compared to the other birds. This is a nicely designed aviary and it's interesting that it's now more than 60 years old.
