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

Trend justification: This species is in decline, probably owing to a combination of natural and anthropogenic habitat loss and brood parasitism (del Hoyo et al. 2004).
