Population justification: The global population size has not been quantified, but the species is described as locally fairly common to rare (del Hoyo et al. 2007). Subspecies macgregori has a tiny but stable population of 50 birds; subspecies tunneyi may number 500 birds and is probably declining; nominate crocea is regarded as common (Garnett and Crowley 2000).

Trend justification: The trend direction for this population is difficult to determine given that there are both positive and negative processes suspected to be affecting it (Higgins et al. 2001).
