Species

Justification
This species is dependent on large tracts of primary or secondary forest, and is therefore likely to be declining moderately rapidly as a result of habitat loss and degradation. It occurs within a small range, in which its habitat and population, however, are not regarded as being severely fragmented or restricted to a few locations. It is therefore currently considered Near Threatened, but the species should be monitored carefully for evidence of further declines.

Distribution and population
Terpsiphone cyanescens is endemic to the Palawan group (Palawan, Busuanga, Culion and Bantac) Philippines, and appears to be fairly common (100 records, 1964-1970) throughout the island (including St Paul's Subterranean River National Park) (Collar et al. 1999).

Population justification
The global population size has not been quantified, but the species is described as uncommon to fairly common throughout Palawan (del Hoyo et al. 2006).

Trend justification
A moderately rapid population decline is suspected to be occurring as a result of habitat loss and degradation within the species's range, particularly given the lack of records from isolated or fragmented secondary forests.

Ecology
This species is confined to primary and secondary forest, mostly in the lower-lying areas. It does not occur in isolated tracts of secondary growth.

Threats
As a forest specialist, this species is threatened by habitat conversion, which is occurring at an increasing rate within its range as a result of logging and agricultural development.

Conservation actions underway
No targeted conservation actions are known for this species, although some of its habitat is protected.

Conservation actions proposed
Conduct repeated surveys within the species's range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Campaign for the long term protection of remaining tracts of lowland woodland on Palawan.
