Population [top]
Population: The global population size has not been quantified, but the species is described as generally common to fairly common, although rare and local in Pakistan (Grimmett et al. 1998), while national population sizes have been estimated at < c.100 introduced breeding pairs in Taiwan and c.100-10,000 introduced breeding pairs in Japan (Brazil 2009).
Trend Justification: The population is suspected to be increasing due to range expansions in Pakistan and Sumatra as ongoing habitat degradation is creating new areas of suitable habitat (Feare and Craig 1998).
Current Population Trend: Increasing
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
