I agree with Ara. I think that the birds are slowly slipping away at Taronga. Don't get me wrong, the new avairies such as Wollemi and the two on the asian trail are great but if you list some of the avairies that have been removed in the last 20 years, such as:
*the Australian birds near B2B,
*the seabird avairies that were oppisite the gorillas,
*the pheasants near the current orang utans,
*the birds of prey near the old orang utans,
*the large wedge tail avairy,
*the empty avairy near the old penguin pool,
*the kookaburra cage across from the tassie devils
*and the small avairies turned into one large one for the mallee fowl above the jungle cats,
more have gone than have been created. fair enough some of the birds that lived in these avairies are still on display but a lot have gone.
