The last wild specimen was killed in Okeechobee County, Florida in 1904, and the last captive bird died at the Cincinnati Zoo on 21 February 1918. This was the male specimen "Incas," who died within a year of his mate "Lady Jane." Coincidentally, Incas died in the same aviary cage in which the last Passenger pigeon, "Martha," had died nearly four years prior. It was not until 1939, however, that it was determined that the Carolina Parakeet had become extinct.
