Last original to opening day is Puppe the Orangutan I believe she's the oldest Sumatran in North America if not the oldest Orangutan in NA.I have a question, are there any remaining animals who have been at the zoo since day 1 in August 1974? I thought Charles the gorilla might have been the last when he died in October, but I want to know if there are any other original animals still there.
As for just older animals we have Pinky, Brain, and, Phoebe, 47 year old American Flamingos who have been here since 1977. As well as Jonah, 51 Great Concave Casqued Hornbill not sure when he arrived but he's been here quite awhile. Not sure the age of the Aldabra Tortoises Queenie and Malila but they arrived in 1975 before leaving briefly in 1999 and returning in 2016. I think those are all the oldest animals from a human standpoint rather than just life span of individual species.
