3l6 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



above metallic green ; central rectrices bronze-green basally, blue- 

 black at tip ; others blue-black ; wings dusky with a violaceous sheen ; 

 side of head, foreneck, and upper breast metallic violet-blue; lower 

 breast, abdomen, and sides metallic green to bluish green ; under tail 

 coverts metallic green, edged with white. 



Female, above metallic bronze-green ; middle rectrices the same, 

 but blackish at ends ; others bluish black, tipped with grayish white ; 

 wings as in male ; central under surface including under tail coverts, 

 pure white ; sides metallic green. 



Juvenile, like female but feathers of upper surface edged narrowly 

 with cinnamon-buff; under surface heavily spotted with metallic green. 



An adult male collected at El Potrero, Cocle, March 6, 1962, had the 

 iris dark brown ; maxilla and tip of mandible black ; base of mandible 

 buffy brown ; tarsus, toes, and claws black. Two males from Puerto 

 Obaldia, San Bias, February 18, 1963, and Puerto Armuelles, 

 Chiriqui, February 21, 1966, were similar, except that the base of the 

 mandible in the first was dull reddish flesh color, and in the second 

 pale pink. 



Measurements. — Males (11 from Panama), wing 48.3-50.8 (49.4), 

 tail 30.1-33.8 (32.2), culmen from base 18.2-19.9 (19.1) mm. 



Females (10 from Panama), wing 46.3-49.9 (48.3), tail 27.0- 

 30.1 (28.9), culmen from base 18.2-21.7 (19.7) mm. 



Resident. Common in the lowlands on the Pacific slope from 

 western Chiriqui to the coastal area of western Darien; on the 

 Caribbean slope from the lower Chagres Valley to the Colombian 

 border. Isla Coiba ; Isla Cebaco. 



The bird was described by Gould from David in Chiriqui. I have 

 found it in this general region below Alanje, toward the sea, and 

 at Olivo, in the Puerto Armuelles area; in late February I secured 

 2 in mangroves. In 1953 it was abundant near Sona in western 

 Veraguas. There are early records by Arce for Castillo and Calobre, 

 but the report for Santa Fe (Salvin, Proc. Zool. Soc. London, 1867, 

 p. 156) is doubtful, since it is the only record from the highlands, 

 made at a time when Salvin's notations as to localities were sometimes 

 uncertain. The species is common in the lowlands of the eastern 

 side of the Azuero Peninsula to beyond Pedasi. In eastern Panama 

 I have found it east to the mouth of the Rio Maje, and it occurs 

 also in southwestern Darien around the shores of Golfo San Miguel 

 (Punta Sabana, Garachine, mouth of the Rio Sambu). This is the 

 known eastern boundary on the Pacific side as none have been found 

 inland along the lower Rio Tuira. The species crosses through the
