Crested Jay Platylophus galericulatus

Justification
This species is relatively scarce across its range, and is restricted to forest habitats. It is likely to be declining moderately rapidly overall, as a result of on-going habitat loss. It is therefore currently considered Near Threatened, and should be monitored carefully.

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
Platylophus galericulatus is restricted to the Sundaic lowlands, from south Tenasserim, Myanmar, peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Kalimantan, Sumatra and Java, Indonesia and Brunei (BirdLife International 2001). It is generally uncommon throughout this range.

Population justification
The population size of this species has not been quantified; it is considered locally common.

Trend justification
A moderately rapid population decline is suspected to be occurring as a result of forest clearance. The rate of decline is not believed to be more rapid because the species may be tolerant of secondary habitats.

Ecology
This species occurs in lowland evergreen forest, both primary and tall secondary, up to 1,500 m.

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 hill and submontane forests, which are under less pressure from logging and agricultural conversion.

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 within the species's range to determine its current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community-led multiple use areas.
