Population justification: The global population size has not been quantified, but this species is described as 'uncommon' (Stotz et al. 1996). However, in Brazil the species is common in Sao Paulo (F. Olmos in litt. 2003), it is also common in Argentina (M. Pearman in litt. 2003), and has been recorded from seven Misiones departments (Chebez 1996) and may occur in others.

Trend justification:

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