Population justification: This is considered a rare species (del Hoyo et al. 2002); the population has been estimated at fewer than 630 pairs (Winkler et al. 1995), placed here in the band 1,000-2,499 mature individuals.

Trend justification: The population trend is suspected to be stable in the absence of any evidence of declines or significant threats.
