I don't even see their exhibit. If they are no show, a sign will put in front of the exhibit, saying they are off exhibit. Where is the exhibit for them? I suppose near the ground hornbill?
(Maybe I just miss them?)
@aardvark250 I seem to remember they were in an aviary with turacos and nearby were vulturine guinea fowls and weavers. It was a couple of years ago, but I guess it must have been in the Africa section near where the okapis were.
