Grey-breasted Babbler Malacopteron albogulare

Justification
This species occurs within a relatively large range, but is scarce and local in most areas. Its habitat requirements are poorly understood. It is suspected to be declining moderately rapidly owing to habitat loss, and is therefore considered Near Threatened. If further studies reveal that it is restricted to primary habitats, or declining at a higher rate than currently thought, its status may change to Vulnerable.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Malacopteron albogulare is restricted to Sabah, Sarawak, and peninsular Malaysia; Sumatra (including Batu Islands and Lingga archipelago) and Kalimantan, Indonesia, and Brunei. There are few recent records from many apparently suitable areas, e.g. North Selangor Peat Swamp Forest, Panti Forest Reserve, Pondok Tanjong Forest Reserve, and South Pahang Peat Swamp Forest, Malaysia (D. L. Yong in litt. 2007), which suggests that it is now rare and declining.

Population justification
The global population size has not been quantified, but the species is described as scarce (del Hoyo et al. 2007).

Trend justification
This species has become increasingly scarce in recent years, and is likely to be declining as a result of widespread habitat loss.

Ecology
This species occurs primarily in the understorey of lowland forests on poor soils, particularly freshwater peatswamp and heath forests on alluvial plains or terraces. In some areas it is restricted to lowland peatswamps and kerangas, although it is also recorded from mixed dipterocarp and dryland forests, lightly-logged forests and forests on sandy or rocky terrain. Its absence in many areas of apparently suitable habitat suggest that it may have specific and unidentified habitat requirements that influence its distribution.

Threats
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). Peatswamp forests are being lost at a particularly high rate, and currently receive relatively scant protection from reserve networks.

Conservation Actions Underway


Conservation Actions Proposed
Conduct repeated surveys within the range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Improve the management of any protected areas within the species's range that are suffering encroachment. Increase the area of suitable habitat that has protected status. Implement measures to reduce the number and severity of forest fires.
