Rock Parrot
Neophema petrophila
John Gould was the first to describe the species, in 1841.
Neophema combines the Greek neos (new or different) and euphema, a generic name no longer in use, itself derived from the Greek euphemos (auspicious or laudatory); petrophila combines the Greek petros (rock) with philos (loving).
