@Summer Tanager These birds are all kept in Zlin, which does really have a first rate bird collection. The downside is that all these birds are mixed in the same aviary, which seems designed more for the vultures, which live there too.... So that didn't convince me at all in terms of hornbills and turacos.
@lintworm Thank you! I agree! Although turacos can be tough birds, I wouldn't mix them in an aviary with vultures, Secretary Birds, or even large hornbills!
