Population justification: The population numbers probably about 2,500-3,000 mature individuals, as was estimated in 2002 (D. Ball in Julien et al. 2020). The figure is consistent with counts of 5,100–7,797 adults and immatures during the non-breeding season (Julien 2017) and estimates made using previous methodologies, e.g.: (1) 2,205–3,160 derived from the product of 0.25 birds/ha (derived from counts in 12 2-ha plots) and the area of vine forest in Eungella National Park (88 km2 above 900 m [excluding the 4.7 km2 burnt in 2019]; Julien et al. 2020); and (2) an estimate of 3,400 (2,400–4,700) which is the product of the density of its closest relative, the Bridled Honeyeater B. frenatus (0.41 birds/ha, 95% confidence 0.29–0.57; Anderson et al. 2015) and the area of high altitude rainforest (88 km2). To encompass these uncertainties, the population is considered here to number between 2,000 and 4,700 mature individuals, with a best estimate of 2,500-3,000.

Trend justification:

The population was estimated at 2,500 mature individuals in 2002, which is roughly consistent with counts and estimates from recent years, suggesting that the population is stable (Julien & Garnett 2021). Variation in counts outside the rainforest (Julien 2017) are considered likely to reflect variation in breeding success rather than continuing decline. Population losses caused by wildfires in 2019 are assumed to have ceased, although this threat may become increasingly frequent (with climate change) in the future and has the potential to cause population declines.
