I am planning to open a zoo in the future. I always thought an aviary would be cool. I plan to house my different bird species from around the world. Here's my ideas: Budgerigars (What a surprise.) Cockatiels Zebra Finch Gouldian Finch Domestic Canary House Sparrow Northern Cardinal Blue Jay Vermillion Cardinal American Robin Red-Winged Blackbird Baltimore Oriole You are probably wondering right now why there are some "mundane" birds such as the Cardinals and Orioles? The reason why is to display to guest how diverse birds can be and create an interesting exhibit with birds they see everyday and birds they may have never seen before. Yes, I will be a good boy and give all the bird the proper space and hiding places. My real question is if this can work. I'm not sure if all these birds can get along. Another concern is that some will attack the visitors. The last thing I need is dead birds on the ground and people running and screaming while getting their eyes are pecked out. What birds should I keep and which should I leave out?
