CARNABY’S BLACK COCKATOOS — AUTOPSY RESULTS
5270. Hon Lynn MacLaren to the Minister for Mental Health representing the Minister for Environment
(1) Is the Department of Environment and Conservation is aware of any observations or autopsy results which indicate that Carnaby’s Black Cockatoos that consume green canola pods suffer paralysis? If yes to (1), will the Minister table copies of any observations or autopsy results that relate to this problem?
(2) What work is being done to assess this risk to this highly threatened species?
(3) Will the Minister table details of any work that has been done?
Hon HELEN MORTON replied:
(1) No
(2) Not applicable
(3) Autopsies are regularly undertaken on suspicious deaths of Carnaby’s cockatoos. Perth Zoo has advised that there is no evidence from post mortems, pathology or similar studies at Perth Zoo or the Department of Agriculture and Food to support any claim that the consumption of green canola pods by Carnaby’s cockatoos causes them to suffer paralysis. Field observations have indicated that these birds may benefit from eating canola seed, as well as the related weed species wild radish and wild turnip.
(4) There are no studies to table to support this proposition.
