Taxonomic note
Ducula spilorrhoa (del Hoyo and Collar 2014) was previously split as D. spilorrhoa, D. subflavescens and D. constans following Sibley and Monroe (1990, 1993), but D. constans was subsequently lumped with D. spilorrhoa because Christidis and Boles (2008) did not recognize it (an Australian endemic) as a separate species. D. bicolor, D. luctuosa (del Hoyo and Collar 2014, Sibley and Monroe 1990, 1993) and D. spilorrhoa (del Hoyo and Collar 2014) are retained as separate species contra Christidis and Boles (2008), who included constans, spilorrhoa, subflavescens and luctuosa as subspecies of bicolor.

Population justification: The global population size has not been quantified, but the species is reported to be uncommon to seasonally or locally common (del Hoyo et al. 1997).

Trend justification:

The species is tentatively assessed as being in decline due to habitat loss per Tracewski et al. (2016).
