Population justification: Partners in Flight estimate the total population to number 50,000-499,999 individuals (A. Panjabi in litt. 2008).

Trend justification: The population is suspected to be increasing as ongoing habitat degradation is creating new areas of suitable habitat (Madge and Burn 1993).
