The brown-headed parakeet is only known from two museum specimens, about whose year of origin there are contradicting statements. While Erwin Stresemann (1950) and James Cowan Greenway (1958) named the years 1773 or 1774, the New Zealand ornithologist David George Medway (1939-2013) assumed on the basis of old travel diaries that these specimens were in November 1777 during the third Cook -South Sea voyages were shot. Today they are in the Natural History Museum in London and in the Natural History Museum in Vienna . Nothing is known about the reasons for its extinction, but it is believed to have died out shortly after its discovery.
