NT
Black-and-yellow Broadbill Eurylaimus ochromalus



Justification

Justification of Red List Category
This species is likely to be declining moderately rapidly throughout its range as a result of the continuing destruction and degradation of forest habitats. It is therefore considered Near Threatened.

Population justification
The population size of this species has not been quantified, but it is described as locally common.

Trend justification
A moderately rapid population decline is suspected to be occurring in line with rates of habitat loss throughout the species's range.

Distribution and population

Eurylaimus ochromalus is confined to the Sundaic lowlands, where it is recorded from south Tenasserim, Myanmar, peninsular and west Thailand, Sabah, Sarawak and Peninsular Malaysia, Singapore, Kalimantan (including the Natuna Islands) and Sumatra (including offshore islands), Java and Bali, Indonesia and Brunei (BirdLife International 2001). It remains locally common in areas of suitable habitat.

Ecology

This species occurs in a variety of forest types including primary lowland evergreen forest, mixed dipterocarp forest, swamp forest and forest edge, as well as secondary growth and adjacent plantations. It occurs mainly in the lowlands, up to 1,200 m in some areas. Persistence in logged forests, secondary habitats and plantations is dependent on the presence of many remnant tall trees.

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 secondary forest.

Conservation actions

Conservation Actions Underway
No targeted conservation actions are known for this species, although it occurs in a number of protected areas.

Conservation Actions Proposed

Conduct repeated surveys across the species's range to determine the magnitude of declines and rates of range contraction. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Campaign for the protection of remaining tracts of lowland forest throughout the species's range.
