This species has been downlisted to Least Concern as it has been found to have a high tolerance of habitat degradation and disturbance, and deforestation may even be increasing the amount of suitable habitat. It is not believed to be a regular target for hunters and the population is therefore suspected to be stable or increasing. It has a very large range and thus does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be <10% in ten years or three generations, or with a specified population structure).
