Population justification: Although a full population census is yet to be completed, the species is thought to be rare at all known sites in Guatemala, there are few recent records from Mexico, Honduras and Nicaragua, and no recent records from El Salvador. Considering this, the population is thought to hold fewer than 10,000 individuals (K. Eisermann in litt. 2010), hence is best placed in the band 2,500-9,999 individuals, which roughly equates to 1,500-7,000 mature individuals.

Trend justification: This species is thought to have undergone a moderately rapid decline in the past decade, largely through the severe impacts of widespread human-induced habitat alteration and overhunting (R. Gallardo et al. 2012); forest loss within the species's range currently totals ~3% per decade (Tracewski et al. 2016). The rate of decline was suspected to total between 30-49% during the past 10 years as habitat loss and hunting increased throughout its stronghold of Guatemala as a result of human population increases and opencast mining (Eitniear and Eisermann 2009; K. Eisermann in litt. 2010).
