 19, p. 94. (New Grenada, line of Panama Railroad.) 



Habia rubica aurantiicapilla Aldrich, 1937, Sci. Publ. Cleveland Mus. Nat. Hist., 

 7, p. 132. (Cerro Viejo, altitude 3000 ft, between the headwaters of the Negro 

 and Mariato Rivers, 18 miles east of Montijo Bay, Veraguas, Panama.) 



Medium size; adult male, dull red, with brighter patch on center of 

 crown; female and immature male mostly olive with orange-yellow 

 patch in center of crown. 



Description. — Length 162-177 mm. Adult male, center of crown be- 

 tween coral red and scarlet, edged blackish; rest of upper surface, in- 

 cluding wing coverts, dull red; remiges and rectrices slightly brighter; 

 entire undersurface slightly lighter red, brighter on throat. 



Adult female, center of crown orange-yellow; rest of upper surface 

 olive; throat tinged yellow; breast, sides, flanks, and undertail coverts 

 olive-brown; center of undersurface lighter. 



Immature male, like female. 



A female collected at El Cope, Code, on February 21, 1962, had the 

 iris light mouse brown; maxilla dull black, except cutting edge, which, 

 with mandible, was fuscous-brown; tarsus fuscous-brown; toes grayish 

 fuscous-brown. 



Measurements. — Males (10 from Panama), wing 86.8-97.0 (89.7), 

 tail 74.4-81.8 (78.2), culmen from base 17.1-19.3 (18.6), tarsus 21.8- 

 24.7 (22.7) mm.

 (73.5), culmen from base 17.5-19.1 (18.2), tarsus 20.8-23.1 (22.0)

Resident. Fairly common but local in forest and woodlands on the 

 Pacific slope in lowlands and foothills; in the Canal Zone area, where 

 it is scarce, it also occurs locally on the Caribbean slope in the middle 

 Chagres River Valley (Ridgely, 1976, p. 323). In Chiriqui, W. W. 

 Brown, Jr., collected it at Boquete and Volcan de Chiriqui between 1200 

 and 2250 m. This race is also found in Costa Rica; 16 other races, rang- 

 ing from central Mexico to northeastern Argentina and southeastern 

 Brazil, are recognized. 



Birds from west of the Canal Zone were separated by Aldrich 

 (1937, Sci. Publ. Cleveland Mus. Nat. Hist., 7, p. 132) under the name 

 aurantiicapilla, a race that has not generally been admitted. The 

 scarcity of specimens from the Canal Zone eastward makes compari- 

 son difficult, but the few available specimens do not appear to be con-
