Taxonomic note

Chloropsis cochinchinensis and C. moluccensis (del Hoyo and Collar 2016) were previously lumped as C. cochinchinensis following Wells et al. (2003).

Population justification: The population size is unknown, but the species has been considered rare for some time (Wells 2016). More recently it has been only infrequently observed at sites where it was easy to see in the recent past (Eaton in litt. 2016), or indeed has completely disappeared (S. van Balen in litt. 2019).

Trend justification: The population is suspected to be undergoing a very rapid decline owing to capture for the cage bird trade, which may be exacerbated by past habitat loss greatly reducing the area of suitable habitat. The entire range is considered accessible to trappers and the species is assessed as being in high demand for the cagebird trade (Symes et al. 2018). Leafbird species experienced a surge in popularity as cagebirds after 2012, with all species becoming more desirable and numbers being sold increasing rapidly. Initial reports from repeated visits to sites where the species was commonly seen in the late 1990s are that the species has disappeared or is now very scarce (B. van Balen in litt. 2019). Expert opinion from the IUCN SSC Asian Songbird Trade Specialist Group (ASTSG in litt. 2018) considers that the current suspected rate of decline in the species exceeds 50% and, in the absence of any expectation of a reduction in market demand or restriction on trapping activity, is expected to continue at this very rapid rate.
