Population justification: The population size of this species has not been quantified, but it has been described as locally common. |
|
Trend justification: Data on precise population trends are lacking, but a moderately rapid decline is suspected, as a result of widespread habitat loss and degradation, as well as mortality from hunting and trapping. |
