Measurements. — Males (10 from Panama and northwestern Co- 

 lombia), wing 215-224 (219.8), tail 149-157 (152.1), culmen from 

 base 135.6-173.0 (160.5), tarsus 51.4-57.2 (54.6) mm. 



Females (10 from Panama and northwestern Colombia), wing 

 211-233 (219.7), tail 142-163 (151.4), culmen from base 142.2-156.0

Resident. Common locally in forested areas ; on the Pacific slope 

 from the Costa Rican boundary in western Chiriqui, including the 

 Burica Peninsula, Cerro Pando, the western base of Volcan de 

 Chiriqui to 1,250 meters near Santa Clara and El Volcan, and the 

 coastal area to Alanje and David ; also in the far eastern area of the 

 Province of Panama from the Rio Maje east through Darien to 

 Colombia, ranging to 550 meters on Cerro Pirre, and to 1,500 meters 

 on Cerro Tacarcuna; on the Caribbean side on the Rio Changuena, 

 Bocas del Toro, throughout to the Colombian boundary. 



The species has not been reported on the Pacific side between 

 central Chiriqui and central eastern Province of Panama, or from the 

 whole of the Azuero Peninsula. In my personal field work I have 

 found it most common in the lower Chagres Valley, and in Darien in 

 the valley of the Rio Tuira and the coastal area to the south, includ- 

 ing the Rio Jaque. 



In flight and general aspect in the forest it is closely similar to the
