LC
Bornean Whistling-thrush Myophonus borneensis



Justification

Justification of Red List Category
This species has a very large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Population justification
The global population size has not been quantified, but the species is described as moderately common and widespread (del Hoyo et al. 2005).

Trend justification
The population is suspected to be in decline owing to ongoing habitat destruction and fragmentation.

Distribution and population

This species is endemic Borneo, Indonesia and Malaysia.

Ecology

This species is found in forest from sea level to 2,400 m altitude, occasionally to 2,700 m on Mount Kinabalu (Clement and Hathway 2000, Collar 2004). It is most often found along gullies and streams (Collar 2004).

Threats

This species is threatened by ongoing habitat destruction and fragmentation.
