4 thoughts on “Long-bearded Honeyeater (Melionyx princeps)”
As with many high altitude restricted-range species, it is very poorly-known and might well have an AOO <2000 km2 and population <10,000. If we map known locations, and not extrapolate to unsurveyed locations, the AOO is <2000 km2. Please consider a NT B2(a)+(b)
Many thanks to everyone who has contributed to this discussion. We greatly appreciate the time and effort invested in commenting. The window for consultation is now closed and we are unable to accept any more comments until 22 May 2026. We will now analyse and interpret the information, and we will post a preliminary decision on this species’ Red List category on this page on 22 May 2026, when discussions will re-open.
Many thanks to G. Dutson for the helpful comment above. Overlaying a 2 x 2 km grid over the mapped range yields an AOO value of approximately 14,000. It is noted that only a proportion of this range is likely to be occupied, however even at 20% occupancy this would exceed the threshold of 2,000 km2. Additionally, the species is thought likely to occur in areas of suitable habitat/elevation beyond the currently known localities (Beehler and Pratt 2016). To be considered approaching thresholds under Criterion B there must also be a continuing decline in EOO, AOO, habitat area/extent/quality, locations/subpopulations, or mature individuals. There is currently no evidence for this, and habitat loss is minimal within the species’ elevational range.
Based on available information therefore, our preliminary proposal for the 2026 Red List would be to adopt the proposed classifications outlined in the initial forum discussion.
There is now a period for further comments until the final deadline on 31 May 2026, after which the recommended categorisations will be put forward to IUCN.
The final 2026 Red List categories will be published on the BirdLife and IUCN websites in November 2026, following further checking of information relevant to the assessments by both BirdLife and IUCN.
