Some of the ancient buildings in many European zoos are quite intriguing, but it's often difficult for the structures to fit into the 21st century, modern zoological park.
A '21st century, modern zoological park' should not be ashamed to embrace and integrate its past in its presentation. 'Nur wer die Vergangenheit kennt, hat eine Zukunft.' Only he who knows the past, has a future. Karl Wilhelm von Humboldt Call me nostalgic and 'Old School', but I think that the reasonable and tasteful integration of historic zoo building, considering modern husbandry ideas, can also add a nice individual charm to a zoo.
@Example. Best example for hat is Breslau, its amazing, what they have done out of the old buildings and gave them a future with good animal exhibits, with exception of the pachyderm house, but this is one the next big projects of the zoo.
Is it just domesticated breeds of chicken and pigeons in this building or are some (rare) exotic species found here as well?
I think now there are only domestic breeds and possibly some wild Gallus species, although Gallus varius wasn't there anymore this summer
When I was last there there were wild-form Gallus gallus and Columbia livia (wild-form externally, at any rate - whether they're completely pure I cannot say).
