@Shellheart, probably not those parts then. It is strange because in Europe I have seen only in 2 out of 87 zoos, vultures in an open air exhibit of which in 1 (Duisburg) the vultures still breed because there are no large mammals in with them... Wheareas this seems really common in US zoos.
But also the crowned crane is here just for the scenery (why don't they buy a nice plant fur such things), crowned cranes will never breed in a mixed exhibit with hoofstock.
