Black-banded Barbet Psilopogon javensis


Justification of Red List category
This species has a moderately large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over three generations). The population size is unknown, but is not suspected to be sufficiently small to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The population size of this species has not been estimated, although it is described as uncommon (Eaton et al. 2021) but is frequently encountered in forest blocks across Java (Squires et al. 2021, eBird 2022), including in small, isolated patches (Dewi and Kurnianto 2021).

Trend justification
Historically this species has undoubtedly declined substantially, with forest cover on Java having been reduced by more than 85% since pre-exploitation. However, over the past 20 years, there has been little-to-no forest loss on Java (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein) and most remaining substantial patches lie partly or wholly in protected areas (UNEP-WCMC and IUCN 2022). The species is very occasionally captured for the bird trade (see, e.g., Chng et al. 2018) and this may be causing very slow declines.

Distribution and population

This species is endemic to Java, Indonesia, where it is widespread and often common in suitable habitat, although this is now highly fragmented (BirdLife International 2001).


This species inhabits open evergreen and hill forest, including teak forest, open woodland and woodland fragments. It is found mostly in the lowlands below 1,000 m, but locally to 1,500 m.


Forest destruction in the lowlands of Java has historically been extremely extensive as a result of logging and conversion to agriculture; however, this has since nearly ceased and forest loss since 2000 on the island has been minimal (Global Forest Watch 2022, based on data from Hansen et al. [2013] and methods disclosed therein). It is also sometimes trapped and traded as a cage-bird (e.g., Chng et al. 2018), although this is not thought to be causing substantiative declines.

Conservation actions

Conservation Actions Underway
No targeted conservation action is known for this species, though it does occur several national parks, such as Gunung Gede and Gunung Halimun (eBird 2022).

Conservation Actions Proposed
Conduct repeated surveys across the species' range to determine the population trend. Conduct ecological studies to determine precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Continue to protect areas of suitable habitat. Raise awareness of the species and its status in an effort to reduce trapping.
