Alophoixus bres, A. frater and A. tephrogenys (del Hoyo and Collar 2016) were previously lumped as A. bres following Sibley and Monroe (1990, 1993).

Population justification: The global population size has not been quantified, but the species is described as common to very common (del Hoyo et al. 2005). One of the most highly traded birds in Java, exploitation may be leading to considerable population declines.
Trend justification: Within the last ten years, it has been recorded at remaining forested sites scattered across Java (all considered accessible to trappers), and in several locations on Bali (eBird 2019). From the numbers recorded in trade, a continuing population decline can be inferred within the species’s range due to exploitation. While the rate of decline has not been quantified, it could potentially be as high as 98% over 10 years (Symes et al. 2018). Until detailed information becomes available, the rate of decline has tentatively been placed in the band 10-25% over ten years.
