I fantasies about building a giant aviary (let's say 5km by 5km), but often get lost in thought when trying to decide what to put in it. I have three factors I would want to stick too: Most endangered species As many species as possible Species that particularly compliment each other ecologically I live most in Northern England so a wet but not to hot, not to cold kind of place - this is where it would be. I'm new to ZooChat and super impressed by all of your fantasy zoos etc... I'd love to here how or what you'd all come up with to tackle the above situation? What exactly would go in this giant aviary..?
