Woolly-necked Stork? When I go in 2006 this stork was with the Ruppell's Griffon in the raptor battery. And I cant's see white-browed robin chat in all the zoo :-(
And in the African Aviary was also Scarlet Ibis and Black-necked Stilt, both American birds.

The Scarlet Ibis have now been moved to a smaller aviary next to the new Bird House i believe.

Yeah, the Scarlet Ibises have been moved to the aviary which belongs to the Blackburn Pavilion. The mentioned mixed species aviary doesn't exist anymore, the only one female Woolly-necked Stork moved to this walk-through exhibit for a while ...

Nice design it blends in very well and adds a very good contrast to the elder Old Camel House behind and the Very bulky Casoon Pavillion behind.

that's actually the stork and ostrich house, designed in 1896 by Charles Brown Trollope. I think the camel house you are referring to is the Decimus Burton clock tower, originally the 'Llamas hut' over by the parrot house, which is far smaller but bears a resemblance. I don't think the stork and ostrich house is actually listed.

This photo actually makes the Casson pavilion [behind] look attractive. I am very fond of the old Stork & Ostrich House, which used to house several species of Cranes, as well as Storks, Ratites & 'oddities' like Giant Anteater & Aarkvark; it was also where a lot of the hand rearing of pheasants, waterfowl and even penguins was done at one time.
