The oldest parrot ever is Cookie, a Major Mitchell’s cockatoo (Cacatua leadbeateri) who was at least 82 years and 88 days old when he passed away on 27 August 2016.
Cookie’s exact age was unknown when he arrived at Brookfield Zoo in May 1934. His arrival was documented in a ledger dated May 1934, when he was estimated to be at least one year old. The zoo gave him a “hatch date” of 30 June 1933, which would make Cookie 83 years 58 days old.
Because the precise day in May 1934 was not documented, the age calculation in this record is taken from the final day of the documented month of arrival at the zoo (although the parrot may have been a full 30 days older if his arrival had been on 1st May).
