Justification of Red List category
The species has undergone a population reduction of about 50% since 1970 (Rosenberg et al. 2016). Even though the rate of decline appears to be slowing down recently and the species's range might be larger than previously assumed, the population reduction is projected to continue. It is therefore precautionarily listed as Near Threatened.
