576 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



but apparently less than a year old, taken near Puerto Armuelles, 

 Chiriqui, March 13, 1966, had the iris light yellow; sides of maxilla 

 and all of mandible very pale grayish white, becoming darker on base 

 of mandibular rami; rest of maxilla pale brownish white, darker on 

 the base of the culmen. 



The distal half of the bill in most is distinctly light-colored, ap- 

 pearing quite yellow in birds in full plumage. In juvenile individuals 

 the bill is darker, but not as deep in color as the slaty black of the 

 juvenile Campephihis melanoleueos malherbii. 



Figure 75. — Foot of flint-billed woodpecker, carpintero picotero, Campephihis 

 guatemalensis guaicmalcnsis, to show form of outer hind toe. 



Measurements. — Males (10 from Chiriqui and Costa Rica), wing 

 179-189 (184.6), tail 87.8-103.9 (97.2), culmen from base 44.5-50.2 

 (48.0), tarsus 36.0-39.4 (37.8) mm. 



Females, (10 from Chiriqui and Costa Rica), wing 181-190 

 (184.1), tail 93.1-104.4 (98.6), culmen from base 41.0-49.9 (45.8), 

 tarsus 36.0-36.6 (36.2) mm. 



Resident. Fairly common in forested areas in western Chiriqui 

 from the tropical lowlands to 1,350 meters on Cerro Pando, and to 

 1,600 meters above Boquete; in western Bocas del Toro east along 

 the shores of the Laguna de Chiriqui to the Rio Guarumo (Chiriqui- 

 cito) ; to 750 meters on the Rio Changuena. On both slopes it ranges 

 west to the Costa Rican boundary. 



The report by Salvin (Proc. Zool. Soc. London, 1867, p. 157), 

 quoted in Salvin and Godman (Biol. Centr.-Amer., Aves, vol. 2, 1895, 

 p. 447), of a specimen taken by Arce at "Santiago de Veragua" must 

 have been an error as the species is unknown that far to the east.
