Scarlet-breasted Flowerpecker Prionochilus thoracicus

Justification
This forest-associated species is listed as Near Threatened because its population is assumed to be undergoing moderately rapid declines owing to the extensive loss of lowland forests from large areas of South-East Asia. It is not considered more threatened because it can use secondary habitats.

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
Prionochilus thoracicus occurs in the Sundaic lowlands of peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Kalimantan and north Sumatra (including Lingga archipelago and Belitung), Indonesia and Brunei (BirdLife International 2001, Wells 2007). It is considered widespread and fairly common within the region.

Population justification
The global population size has not been quantified, but the species is described as uncommon in Thailand and the lowlands of Borneo, and rare in Sumatra (Cheke et al. 2001).

Trend justification
Rates of forest loss in the Sundaic lowlands have been extremely rapid (Kalimantan lost nearly 25% of its evergreen forest during 1985-1997, and Sumatra lost almost 30% of its 1985 cover), because of a variety of factors, including the escalation of logging and land conversion, with deliberate targeting of all remaining stands of valuable timber including those inside protected areas, plus forest fires (particularly in 1997-1998). However, this species is thought to have avoided rapid declines because it can adapt to secondary habitats, thus it is suspected to be experiencing a moderately rapid decline overall.

Ecology
It occurs in lowland dry-land forest (including peatswamp and heath forest) to 1,280 m. It is recorded from mature secondary and logged forest, and visiting fruits in pioneer regenerating growth. In the Malay Peninsula, the only habitat in which it is numerous is peatswamp forest. It is frugivorous.

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). The magnitude of these threats may be allayed by this species's tolerance of some secondary habitats.

Conservation Actions Underway
None are known. Conservation Actions Proposed
Determine population densities within different habitats and use these to assess the impacts of forest loss, differentiating where possible between primary and secondary forest types. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community-led multiple use areas.
