Réunion parakeet : ウィキペディア英語版 | Réunion parakeet
The Réunion parakeet (''Psittacula eques eques'') was a little-known parakeet, extinct from about 1770, which formerly inhabited Réunion Island in the western Indian Ocean. It was similar to the echo parakeet of Mauritius. The two may either be distinct subspecies of the same species or the same taxon. ==Taxonomy==
Its taxonomy is under question, with some considering it a distinct species, while others considering it to be conspecfic with the echo parakeet. Even in that case, ancient DNA analysis of this specimen will give new insight into these questions, because very little data exists on the genetic diversity of the echo parakeet in former times. In any case, the Réunion and Mauritius birds certainly formed a clade. Until new DNA data is available – and even then only if it would show a significant difference -, it is really a matter of opinion whether one follows a lumper or a splitter approach.
