Species depart the biota, not with a bang but a whimper. The Thylacine, Tasmanian Tiger or Marsupial Wolf, Thylacinus cynocephalus, is one of a handful of species, joining the Quagga, Equus quagga, and the Passenger Pigeon, Ectopistes migratorius, where that whimper has a precise date. The Thylacine became extinct on 7 September, 1936, when the last known specimen died in captivity in the Beaumaris Zoo, Hobart (Smith 1981).
Records, both of employees and the visiting public to Australian zoological gardens displaying
the Thylacine (Adelaide, Hobart, Launceston, Melbourne and Sydney zoos) represent an important and largely untapped data source of additional knowledge upon the behaviour of this species.
