Population justification: Partners in Flight estimate the population size to be 26,000,000 mature individuals (Rosenberg et al. 2016).

Trend justification:

The species is tentatively assessed as being in decline due to habitat loss per Tracewski et al. (2016), warming climate (Waite and Strickland 2006) and exotic diseases.
