Taxonomic note
Psophia viridis, P. dextralis and P. obscura (del Hoyo and Collar 2014) were previously lumped as P. viridis following Sibley and Monroe (1990, 1993).

Population justification: The total remaining population is unlikely to number more than a couple of hundred birds, in two disjunct blocks (A. Lees in litt. 2014).

Trend justification: This species is suspected to lose 77-88% of its extent of suitable habitat in the Amazonian portion of its range (which accounts for c. 88% of its global extent of suitable habitat) over 31 years, as projected after 2002 using a model of forest loss in the Amazon basin (Soares-Filho et al. 2006). By taking the pessimistic (business as usual) scenario of forest loss and factoring in the species’s susceptibility to hunting, fragmentation and edge-effects (following Bird et al. 2011), it is suspected to decline by 87% over three generations from 2002.
