482 BIRDS OF THE REPUBLIC OF PANAMA — PART 3 



1962, also had the iris dark brown ; maxilla black ; mandible dark 

 honey yellow, with a tiny area at the pointed tip fuscous ; tarsus and 

 toes dark brown ; claws black. 



Measurements. — Males (10 from Code, Province of Panama, and 

 Tacarcuna, Darien), wing 59.5-64.0 (62.3), tail 48.5-53.5 (51.4), 

 culmen from base 11.0-12.8 (12.0), tarsus 12.0-12.8 (12.3) mm. 



Females (7 from Veraguas, Code, and Tacarcuna, Darien), wing 

 57.1-61.3 (58.6), tail 46.7-51.0 (49.4), culmen from base 11.4-12.2 

 (11.8), tarsus 12.3-12.6 (12.4) mm. 



Resident. Found locally, in small number, on the mountains of 

 eastern Veraguas (from both Pacific and Caribbean slopes), and of 

 northwestern Code ; Cerro Campana, western sector of the Province 

 of Panama; and Cerro Tacarcuna, Darien (including the eastern 

 face in Choco, Colombia). 



Benson collected one on the Rio Calovevora, on the Caribbean slope 

 of Veraguas, September 3, 1926. My first specimen was a female, 

 taken at 650 meters elevation at Las Peiiitas at the head of Rio 

 Guabal, on the trail leading to the Caribbean lowlands of northern 

 Code. Four from El Valle were collected March 29, 1951, at an 

 elevation of 760 meters in heavy forest along a small stream at the 

 northern end of the Cerro La India Dormida. A few days earlier, 

 on March 21, I had secured one and saw another at 1000 meters eleva- 

 tion on the south face of Cerro Campana. Here, a deadfall that had 

 made a small opening in the forest offered suitable low perches, 

 where two of these flycatchers rested, on the watch for passing 

 insects. 



From Darien, on the base of Cerro Tacarcuna, we have three taken 

 at the ancient village site at 575 meters, and on the high mountain 

 ridge of Cerro Mali at 1280 meters. These birds at times varied 

 from the usual habit of low perches to range in the high tree crown 

 when this faced a small clearing. The height from the ground empha- 

 sized their tiny size, less evident in those encountered near at hand 

 and lower down. 



Webster, in his revision of this species (Auk, 1968, p. 301) with 

 only part of the material now available, assigned the few seen from 

 the Tacarcuna area to the race emimilus. Additional specimens now 

 available indicate clearly that birds of this area are the subspecies 

 vividus. Those of Veraguas, from which the subspecies was de- 

 scribed, show some affinity to aitrantiiventris in the more cinnamon 

 hue of the foreneck and breast. Birds from Cerro Campana and 

 Cerro Tacarcuna, which are definitely paler cinnamon on the breast
