Data Zone
Justification of Red List category
This species has a restricted range, and although much of its habitat remains secure by virtue of its inaccessibility, it is at some risk from habitat loss and degradation, as well as trapping. It is therefore listed as Near Threatened.
Population justification
The global population size has not been quantified. Described as uncommon by Eaton et al. (2021), although Marsden et al. (2023) found them along 77 transects at 21 sites, with an encounter rate similar to other montane endemic passerines. Nijman et al. (2021) estimated that c.1,200-1,500 birds were sold in markets each year, somewhat sustainably. It is unclear what percentage of these are wild-caught; if a majority, this would suggest that the population of L. albonotatus numbers at least several thousand birds.
Trend justification
There are no robust data on the trends of this species. Habitat loss in its range has been minimal over the past two decades, although at the lower elevations of its range there is evidence of some clearance and additional degradation (Global Forest Watch 2024, using data from Hansen et al. [2013] and methods disclosed therein), the impact of which is unknown. The price of L. albnonotatus has remained relatively stable in the past 12 years suggesting that supply of birds is not decreasing (Nijman et al. 2021); however, it is unclear whether all of these birds are wild-caught, nor whether this is strictly a reliable indicator of trend. The trend is therefore considered unknown.
Laniellus albonotatus is restricted to west Java, Indonesia.
This species is found in the canopy and edge of broadleaved montane forest at 900-2,500 m but mostly above 1,400 m (Eaton et al. 2021, Nijman et al. 2021).
Main threat to this species is probably trapping for the cagebird trade, although evidence so far suggests that this is not having a severe impact on populations trends (Nijman et al. 2021). There is some evidence of forest cover loss and degradation at the lowest elevations of its range (Global Forest Watch 2024), though the impact of this on global trends is also relatively unknown.
Conservation Actions Underway
No targeted conservation actions are known for this species but it occurs in numerous protected areas.
Conservation Actions Proposed
Monitor populations and habitat trends at known sites. Repeat surveys (similar to those by Marsden et al. 2023) at regular intervals to determine likely trends. Conduct ecological studies to identify the precise habitat requirements of this species. Monitor the presence of this species in the local bird trade and control if necessary. Protect areas of suitable habitat. Raise awareness of the species and its status in an effort to reduce the potential for trapping.
