I recently bought a old Taronga zoo guide book off e-bay. I think it was from the 40's or 50's. Some of the birds and animals listed at the zoo back then would made any zoo fan drool. Some of the animals in the collection back then included: Barbirusa,lesser kudu,muntjacs,anoas,polar bears,hanuman langurs (entellus monkeys) and hyenas. Some of the birds included: King vultures, bali miners, hornbills and toucans. I am still waiting to receive a couple of other old zoo guides from taronga from the 60's and 70's. Also an old Adelaide guide from the 80's.
