Yes, indeed, I agree. We all know that but the people the zoo needs to attract in large numbers are not like us.
I believe the Eastern white stork moved last year and I'm not sure there are any Darwin's rheas left. The kiwi is still on the TV screen, Argus pheasants are audible somewhere, Southern screamers continue to flourish, only black and wrinkled hornbills on show? The train's not running because of covid19. The big cat enclosures are good but the cats have had to split up as a result of TB so are maybe not so visible to passers by. The Ape House is off limits because of covid19 so if the gorillas choose to stay indoors they're a no-show, likewise the orangs to a lesser extent as they are in two groups. Bruce is only on show if he goes outside. So all these wonders might not be instantly accessible to current visitors.
