FAMILY Til RAUPIDAE

of Darien and northern Colombia; in the Canal Zone and eastern Prov- 

 ince of Panama the populations are intermediate. The race delcticia is 

 poorly marked with adult males having- the lesser wing coverts varying 

 from partly green to light yellow, in contrast to bangsi, which has the 

 lesser wing coverts a darker, somewhat more orange-yellow. Hellmayr 

 (Field Mus. Nat. Hist., Zool. Ser., vol. 13, pt. 9, 1936, p. 146) noted 

 that birds from the Canal Zone are intermediate; this intermediate 

 population extends east at least as far as Cerro Azul, eastern Province 

 of Panama. Other races range to northern Bolivia and Amazonian 

 Brazil. 



TANGARA GYROLA BANGSI (Hellmayr) 



C.[alospiza\ gyroloides bangsi Hellmayr, 1911, Proc. Zool. Soc. London, p. 115. 

 (Boquete, Chiriqui, 3,500 feet, Panama.) 



Characters. — Lesser wing coverts more extensively yellow and of an 

 oranger cast. 



A female collected at El Volcan, Chiriqui, on March 20, 1965, had 

 the iris dark brown; maxilla and tip of mandible fuscous-black; base 

 of mandible dull brownish neutral gray; tarsus brownish gray; toes 

 dark brownish gray; claws fuscous. 



Measurements. — Males (10 from western Panama), wing 73.1-78.0 

 ( 76.6) , tail 48.0-52.3 ( 50.2 ) , oilmen from base 1 1 .6-1 3.9 ( 12.5 ) , tarsus 

 15.2-17.4 (16.3) mm. 



Females (10 from western Panama and Costa Rica), wing 70.5-78.0 

 (74.1), tail 45.1-48.7 (46.5), oilmen from base 12.0-13.5 (12.9), tar- 

 sus 15.3-17.1 (16.3) mm. 



Resident. Common in forests and forest borders in foothills and 

 lower highlands of both slopes, as far east as Code. In Chiriqui, it is 

 less commonly found in the lowlands as well; here, however, it is very 

 local, due to deforestation. Monniche (Blake, Fieldiana: Zool., vol. 36, 

 no. 5, 1958, pp. 565-566) collected it on Volcan de Chiriqui between 

 1560 and 1620 m, and W. W. Brown, Jr., took it at Boquete, Chiriqui, 

 between 1050 and 1440 m (Bangs, Proc. New England Zool. Club, 

 vol. 3, 1902, p. 65). On the western side of the Azuero Peninsula in 

 Veraguas, Aldrich and Bole (Scient. Publ. Cleveland Mus. Nat. Hist., 

 vol. 7, 1937, p. 26) found it uncommon along streams 900 m and above. 

 Kennard (Kennard and Peters, Proc. Boston Soc. Nat. Hist., vol. 38, 

 no. 10, 1928, p. 462) collected a male on the Boquete Trail (690 m) in 

 Bocas del Toro. In Code, I have collected it at El Valle and El Uracillo.
