Population justification: The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996). |
|
Trend justification: Slow to moderate and continuing population declines are likely to be occurring as populations have become increasingly fragmented, and are still influenced by habitat loss and degradation. |
