Geographic Range [top]
Range Description: Pelargopsis amauropterus has a coastal distribution in north-east India (locally common in West Bengal, rare elsewhere), Bangladesh (locally common), Myanmar (fairly common to locally common resident in the south-west and Tenasserim), peninsular Thailand (uncommon to locally fairly common on the west coast) and peninsular Malaysia (fairly common but restricted to islands of the north-west) (BirdLife International 2001). Despite being locally common, its total population may not be very large within this highly linear distribution, as it is largely limited to areas of mangrove, creeks and tidal rivers.

Native:
Bangladesh; India; Malaysia; Myanmar; Thailand

Population [top]
Population: There is no data available on population size, although it is possibly not very large; the species is considered rare to fairly common across its range.
Trend Justification: A moderately rapid and on-going population decline is suspected to be occurring as a result of the continuing destruction and degradation of mangrove forests throughout the speciess range.
Current Population Trend: Decreasing
Additional data:
? Number of mature individuals: Unknown ? Continuing decline of mature individuals: Unknown
? 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: It is usually restricted to coasts, favouring mangroves (particularly dense, old growth forests with large trees [BirdLife International 2001, A. K. Nayak in litt. 2008]), but also frequenting creeks and tidal rivers, although it has been recorded occasionally far inland.
Systems: Terrestrial; Freshwater; Marine
Continuing decline in area, extent and/or quality of habitat: Yes
Generation Length (years): 5.7
Movement patterns: Not a Migrant
Threats [top]
Major Threat(s): This species is likely to be negatively affected by the on-going clearance and degradation of mangroves in South-East Asia.
Conservation Actions [top]
Conservation Actions: Conservation Actions Underway
No targeted conservation actions are known for this species.
Conservation Actions Proposed
Conduct repeated surveys throughout the range to determine rates of population decline and range contraction. Campaign for the protection of remaining mature mangrove forest.
