Geographic Range [top]
Range Description: Pitta caerulea occurs in the Sundaic lowlands, from south Tenasserim, Myanmar, peninsular Thailand, Sabah, Sarawak and Peninsular Malaysia, Kalimantan and Sumatra (not recorded this century), Indonesia and Brunei (BirdLife International 2001). It is scarce or rare throughout its range, although it may be overlooked due to its shy nature. It occurs at low densities, even in optimal habitat (BirdLife International 2001, Yong Ding Li in litt. 2011).

Population [top]
Population: The population size of this species has not been quantified, but it is described as scarce to rare.
Trend Justification: This species is likely to be declining in line with rates of forest clearance throughout its range.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: Unknown ? Continuing decline of mature individuals: Yes
? Extreme fluctuations: No ? Population severely fragmented: No
? Continuing decline in subpopulations: Unknown
? Extreme fluctuations in subpopulations: No ? All individuals in one subpopulation: No
Habitat and Ecology [top]
Habitat and Ecology: This species occurs mainly in primary and tall secondary forests in lowlands and hills, up to 1,200 m. It is most often found in dense, swampy areas, although there are records from overgrown rubber estates, scrub and secondary thickets. Little is known of its precise habitat requirements.
Systems: Terrestrial
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 4.2
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): 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 expansion of oil-palm cultivation is an increasing threat (Yong Ding Li in litt. 2011). The magnitude of these threats may be allayed by this speciess tolerance of hill forest, which is under less pressure from logging and agricultural conversion. Poaching is said to be a potential threat in parts of peninsular Thailand (Yong Ding Li in litt. 2011).
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 speciess 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. Effectively protect significant areas of suitable forest at key sites, in both strictly protected areas and community-led multiple use areas.
