FAMILY THRAUPIDAE 



425 



Resident. Known from western Bocas del Toro near Almirante 

 and. adjacent Costa Rica. The Plain-colored Tanager is little known in 

 western Panama, where it was first reported in 1960, and only 2 more 

 have been secured since then. In late April 1980; Ridgely (in lift.) 

 found it fairly common in small groups in clearings and at forest edge 

 along the lower Changuinola River. This species may be increasing as 

 a result of increased forest clearing. Dr. Paul Slud informs me that he 

 has a few sight records that indicate that the range of this race extends 

 through most of the Caribbean lowlands of Costa Rica.

 ish white, occasionally with a very faint wash of pinkish buff (visible 

 only in the hand) ; lesser wing coverts lighter, brighter blue. 



A female collected at the Candelaria Hydrographic Station, Panama, 

 on March 1, 1961, had the iris dark brown; base of mandible neutral 

 gray; rest of bill black; tarsus fuscous-brown; toes and claws dull, 

 dark neutral gray, washed somewhat with dark brown. 



Measurements. — Males (10 from Panama), wing 67.4-71.4 (68.8), 

 tail 43.4-47.4 (45.6), culmen from base 11.0-11.6 (11.1), tarsus 16.0- 

 17.1 (16.6) mm. 



Females (10 from Panama), wing 65.1-68.5 (66.6), tail 42.2-45.4 

 (43.1), culmen from base 10.4-11.5 (10.9), tarsus 15.8-17.1 (16.6) 

 mm. 



Resident. Common in the lowlands, on the Pacific slope from Cerro 

 Campana, Panama, and on the Caribbean slope from the upper course 

 of the Rio Code del Norte (Cascajal, Code) and the valley of the Rio 

 Indio (El Uracillo, northern Code; Chilar, western Colon), east across 

 the Colombian boundary to northern Choco; ranging up to 650 m ele- 

 vation on Cerro Pirre and Cerro Tacarcuna, Darien, and to 800 m on 

 Cerro Azul/Jefe. 



Salvin and Godman (Biol. Centr.-Amer., Aves, vol. 1, 1883, p. 273) 

 recorded that this bird "has been included in Arce's collections, made 

 probably in the vicinity of Calobre," a town in the lowland hills on the 

 Pacific slope of Veraguas midway between San Francisco and the 

 Code boundary on a tributary of the Rio Santa Maria. As the Plain- 

 colored Tanager has never been recorded this far west on the southern 

 side of Panama, the locality suggested by Salvin and Godman is highly
