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

Trend justification: A slow to moderate population decline is suspected to be occurring, owing to the destruction of Araucaria woodlands. However, data are lacking on the magnitude of this decline.
