=== Hypothetical extinct species ===
The Rothschild's or [[intermediate parakeet]] ''P. intermedia'', found in northern India, was formerly considered a mystery, as only very few specimens were known. It has since been demonstrated to be a [[Hybrid (biology)|hybrid]] between the slaty-headed parrot ''P. himalayana'' and the plum-headed parrot ''P. cyanocephala''.<ref>{{cite journal |last1=Rasmussen |first1=Pamela C. |last2=Collar |first2=Nigel J. |year=1999 |title=On the hybrid status of Rothschild's parrot ''Psittacula intermedia'' (Aves, Psittacidae) |journal=Bulletin of the Natural History Museum, Zoology Series |volume=65 |issue=1 |pages=31–50}}</ref><ref>{{cite journal |last1=Rasmussen |first1=Pamela C. |last2=Collar |first2=Nigel J. |year=1999 |title=Little-known Oriental non-bird: Intermediate parrot, ''Psittacula intermedia'' |url=http://people.ds.cam.ac.uk/cns26/NJC/Papers/Psittermedia%20popular%20Eng.PDF |journal=Bulletin of the Oriental Bird Club |volume=29 |pages=36–41 |access-date=2018-04-10 |archive-date=2018-04-11 |archive-url=https://web.archive.org/web/20180411111424/http://people.ds.cam.ac.uk/cns26/NJC/Papers/Psittermedia%20popular%20Eng.PDF |url-status=live }}</ref>

The taxonomy of the [[Réunion parakeet]] ''P. eques'' is also confusing.  Extinct since 1770, little evidence even exists of the bird's existence. A study skin had been discovered at the Royal Museum of Scotland, explicitly referencing a book description of the Réunion birds. It is known from other descriptions, as well as illustrations of which it is unknown whether they were drawn from live or stuffed specimens.  This may be the only material proof of these birds' existence. Taxonomists are unsure if the birds were a distinct species, or conspecific with the [[echo parakeet]], although genetic analysis supports it being a [[subspecies]] of the echo parakeet.
