Data Zone
Justification of Red List category
This species has a small range where habitat loss/degradation is ongoing, particularly at lower elevations. It therefore qualifies as Near Threatened.
Population justification
This species is poorly known and its population size has not been quantified, though has been described as uncommon to fairly common (B. Beehler in litt. 1994, D. Gibbs in litt. 1994, G. Dutson pers. obs 1997).
Trend justification
There are no data on population trends. Remote sensing data (Global Forest Watch 2024, using data from Hansen et al. [2013] and methods disclosed therein) indicate that forest loss is slow but ongoing: in the three generations (21.6 years) to 2023, 2-3% of forest cover was lost within the range, and since 2017 the rate appears to have accelerated (to a rate equivalent to c.4% in three generations). Given much of this species' range lies above elevations affected by logging however, it is not clear whether this is driving population declines. Trends in area of habitat between 1998 and 2020 have remained stable overall (calculated by sRedList [2023], using underlying data from Jung et al. [2020]) and remaining forest appears to have high intactness (Grantham et al. 2020). The population trend is therefore considered unknown.
Long known only from the montane massif of southern New Ireland, Papua New Guinea, Lorius albinucha was subsequently found on the Lelet Plateau in the middle of the island (Hornbuckle 1999). It is uncommon to fairly common in forest between 500-2,000 m and has occasionally been seen down to 250 m in logged forest (B. Beehler in litt. 1994, D. Gibbs in litt. 1994, G. Dutson pers. obs 1997, Forshaw 2006).
It is a hill forest species, which like other members of the genus, feeds on fruit and flowers. It occurs in forest between 500-2,000 m, occasionally as low as 250 m in logged forest (B. Beehler in litt. 1994, D. Gibbs in litt. 1994, G. Dutson pers. obs 1997, Forshaw 2006).
Logging previously reported to be in operation up to 500 m on the southern massif but unlikely to extend into montane forest (G. Dutson pers. obs 1997, Hornbuckle 1999). Remote sensing data (Global Forest Watch 2024, using data from Hansen et al. [2013] and methods disclosed therein) indicate that forest loss is slow but ongoing: in the three generations (21.6 years) to 2023, 2-3% of forest cover was lost within the range, and since 2017 the rate appears to have accelerated (to a rate equivalent to c.4% in three generations). It is unclear whether this is driving population declines given that much of this species' elevational range lies above that affected by logging, however the apparent acceleration of forest loss in recent years suggest that operations may be expanding to higher elevations.
