Black-throated Babbler Stachyris nigricollis
BirdLife is updating this factsheet for the 2016 Red List
Please email us with any relevant information

This widespread species is listed as Near Threatened because it is suspected to be in moderately rapid decline as a result of habitat destruction and degradation across its range. It is apparently a successful colonist of some secondary habitats, suggesting that the population decline is not more rapid.

Distribution and population
Stachyris nigricollis occurs in the Sundaic lowlands, from peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Kalimantan and Sumatra, Indonesia and Brunei. It is uncommon to fairly common across this range, being most abundant in degraded forests in the lowlands of Borneo. It formerly occurred on Singapore, where it has been extinct since the early 1970s at least (D. L. Yong in litt. 2011).

Population justification
The global population size has not been quantified, but the species is described as generally uncommon to fairly common, although common in Borneo and extinct in Singapore (del Hoyo et al. 2007).

Trend justification
This species's population is suspected to be undergoing a moderately rapid decline owing to habitat loss and degradation throughout its range. Its ability to persist in some modified and disturbed habitats suggests that the rate of decline is not more rapid than this.

This species occurs in primary and secondary evergreen forest, including freshwater and peatswamp forest, from the lowlands up to 1,000 m. Although it is perhaps most abundant in lightly disturbed forests with luxuriant lower-storey growth (e.g. Edwards et al. 2011), evidence from Singapore suggests that it is unable to persist in secondary forest fragments in the long term (Castelletta et al. 2000). In addition, the species is not found in heavily degraded and disturbed habitats such as degraded peat swamp forest (Posa 2011), plantations and scrub (Peh et al. 2006) or in highly fragmented forest (D. L. Yong in litt. 2011).

Rates of forest loss in the Sundaic lowlands have been extremely rapid, owing partly to the escalation of illegal logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas. Forest fires have also had a damaging effect (particularly in 1997-1998). As this species persists in secondary and logged forests, it may not be under immediate threat from selective logging and may be relatively secure in areas where habitat clearance is incomplete, but complete forest clearance (e.g. for plantations and agriculture) remains a real threat.

Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat is protected, e.g. in Taman Negara and Panti Forest Reserve, Peninsular Malaysia (D. L. Yong in litt. 2011).

Conservation Actions Proposed
Conduct ecological studies to improve understanding of its precise habitat requirements and response to fragmentation. Monitor population trends and rates of habitat loss across the range. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community-led multiple use areas.
