Well, the article suggests there will be an aviary within the house for cock-of-the-rock. I agree that pudu are not a tropical forest species, however rodents such as paca or agouti are likely to do more damage. I do feel generally that tropical birds thrive when given access to the outdoors, even if their main enclosure is indoors. Amazon World has many gems, but is lacking in breeding successes among their most rarely seen bird species IMO. I felt the same way about primates being kept permanently indoors, however the condition of the monkeys in the clore rainforest at ZSL is superb, I now wonder if, with the right air circulation and humidity, if this needs to be the case.
