Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).

Trend justification: This species's habitats are affected by cattle grazing and agriculture (del Hoyo et al. 2004), and the species is suspected to be in decline as a result.
