I have never stopped to think about a canary in the concept of a wild animal that naturally exists somewhere. All of my life really I have been thinking of the canary - much like as is here - as something which is kept in a cage or aviary.
Though that's not to say it doesn't mean a place calling itself the National Aviary couldn't have something more substantial and substantially interesting for both visitors and birds.
@dillotest0 I would love to see wild-type canaries in an exhibit! In this case, the cage is an important part of the story they're telling with this hall. Miners would put canaries in tiny cages and keep the birds with them while they worked. If the canary suddenly died, they knew there was some sort of toxic gas and they needed to get out of there. The exhibit uses this history of the species to compare it to birds, especially indicator species, becoming endangered. I think it's a really well-done exhibit, one I haven't seen before and which clearly has a lot of thought put into it.
