Resident. Found locally in forested areas through the tropical zone, 

 to 1,200 meters in Chiriqui (Barriles) ; apparently most common on 

 the Pacific slope. 



The species has not been recorded to date from Bocas del Toro nor 

 from Darien, though it should be found. A specimen taken by Mrs. 

 Davidson Terry at Barriles is the only record for Chiriqui. They are 

 fairly common in northern Herrera, and range to the southern end 

 of the Azuero Peninsula, below Pedasi.
