No more greater bird-of-paradise on-show, then, or have they moved elsewhere?
On my visit last year these aviaries had twelve-wired, twelve-wired, raggiana, greater, and king birds of paradise in them, from left to right. The only other aviaries for birds-of-paradise in the zoo were one for twelve-wired next to the new kiwi house, and one in the Tropenwaldhalle for an elderly twelve-wired male, I assume "Van Dyke".
@Vision The former Greater aviary is now home to a second Raggiana, this was the only bird we did not see, the inhabitants of the other aviaries were very showy. There is also still a Twelve-wired in the Tropical hall, but not elsewhere anymore.
