Species Authority: Sharpe, 1892
Common Name(s):
English Hose's Broadbill
Synonym(s):

Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Benstead, P., Gilroy, J., Taylor, J.
Justification:
This species is likely to be in moderately rapid decline owing to habitat loss and degradation in the lower parts of its elevation range, and is therefore considered Near Threatened.

Geographic Range [top]

Range Description: Calyptomena hosii is patchily distributed in Sabah and Sarawak, Malaysia and Kalimantan, Indonesia (BirdLife International 2001). It is apparently quite common in the Baram drainage, very common in Liang Kubung and recorded in upper Telen, but absent or rare on intervening mountains.

Population [top]

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

Habitat and Ecology [top]

Habitat and Ecology: It occurs in the upper zone of mixed dipterocarp forest on hill slopes, and in lower montane forest. Most records are between 600 and 1,220 m, occasionally up to 1,680 m.

Systems: Terrestrial

Threats [top]

Major Threat(s): Forest loss in the Sundaic region has been rapid and widespread, and is likely to have affected the lower altitudinal range of this species. However, its presence in sloping montane forest suggests that it is not imminently threatened, although logging activities in these habitats are increasing.

Conservation Actions [top]

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. Protect areas of suitable habitat and safeguard against logging and other threats.
