Blue-backed Parrot (Tanygnathus sumatranus) - HBW 4, p. 393

French: Perruche de Müller German: Everettpapagei Spanish: Loro de Müller
Other common names: Müller's/Azure-rumped Parrot

Taxonomy: Psittacus Sumatranus Raffles, 1822, Butung.
Proposed race mulleri is synonym of nominate, and indeed species formerly listed as T. mulleri; birds of Banggai have been awarded race incognitus, based on supposedly different iris colour, but data come from unreliable labels. “T. heterurus” (Rufous-tailed/Salvadori's Parrot) probably described from an aberrant specimen of present species. Six subspecies recognized.
