Beehler & Pratt (2016) treated the Biak population as a subspecies of the polytypic and widespread Rainbow Lorikeet. This taxon is a member of a hyper-variable lineage for which species boundaries are problematic and full molecular analysis is needed. Conversely, del

), which dramatically changed their attitude to the taxon. It is difficult to determine when it began to decline on Biak, but clearly much smaller numbers were present from
.2000 onwards. Birders now make special efforts to seek this endemic but invariably struggle to see more than one or two. However, these observations are all from southern Biak, the most heavily populated and degraded part of the island. Large areas of apparently undisturbed forest persist in northern Biak and over much of Supiori, and a survey of these areas to determine the status of the taxon there is much needed. M. Halaouate (
