Pending molecular analysis, Christidis & Boles (2008) have suggested on biogeographical grounds that the taxon is likely to be most closely related to the Norfolk Island green parrot (Cyanoramphus cookii), as either a subspecies of what they have tentatively called the Tasman parakeet (Cyanoramphus cookii subflavescens), or possibly a full species (Cyanoramphus subflavescens).[4]
Description
By Gönvold
The Lord Howe parakeet was a medium-sized green parrot with a crimson cap and eye-stripe. Measurements of specimens indicate that it was slightly larger than the nominate subspecies, as well as having yellower plumage and less extensive red markings on the head.[5]
Extinction
The parrot was formerly abundant on the island, but was persecuted by the early settlers there because of its raids on their crops and gardens. It was last recorded in 1869.[6][7]
