Population [top]
Population: The global population size has not been quantified, but the species is described as common to locally very common (del Hoyo et al. 2007), while national population sizes have been estimated at c.10,000-1 million breeding pairs in China and c.100,000-1 million breeding pairs in Taiwan (Brazil 2009).
Trend Justification: The population trend is difficult to determine because of uncertainty over the impacts of habitat modification on population sizes.
