532 BIRDS OF THE REPUBLIC OF PANAMA — PART 2 



Resident. Tropical and lower Subtropical Zones on the Pacific 

 slope from western Chiriqui (Santa Clara, El Volcan, Nueva Suiza, 

 Concepcion, Divala, Bugaba, and Cerro Flores) to western Veraguas 

 (Zapotillo). 



One that I saw but did not secure near Tonosi in Los Santos in 

 March 1957, may have been of this race. 



The bird ranges in southwestern Costa Rica to the valley of the 

 Rio Terraba and its principal tributaries. In Panama I have not 

 taken it east of Zapotillo in western Veraguas (20 kilometers from 

 the boundary with the Province of Chiriqui). I encountered it there 

 near the small streams that reach the sea through the mangroves 

 near the mouth of the Rio Tabasara. 



PICUMNUS OLIVACEUS PANAMENSIS Ridgway 



Picumnus olivaceus panamensis Ridgway, Proc. Biol. Soc. Washington, vol. 24, 

 February 24, 1911, p. 34. (Lion Hill Station, Panama Railroad, Canal Zone, 

 Panama.) 



Characters. — Brighter, more greenish above, with the edgings of 

 the inner primaries and secondaries lighter, more yellowish green; 

 lighter below, with upper breast more buffy brown, and lower breast, 

 abdomen, and sides, definitely yellower. 



A male, collected near the La Jagua Hunting Club, east of Pacora, 

 Panama, January 14, 1962, had the iris wood brown; bill black, 

 becoming dusky neutral gray at the base; tarsus, toes, and claws 

 neutral gray with a faint greenish tinge ; toe pads slightly yellowish. 



Measurements. — Males (12 from Panama), wing 50.1-51.2 (50.5), 

 tail 23.8-27.0 (25.8), culmen from base 11.4-12.9 (12.0), tarsus 

 11.8-13.3 (12.5) mm. 



Females (10 from Panama), wing 48.1-51.5 (50.1), tail 23.4- 

 26.7 (25.2), culmen from base 11.0-12.8 (11.9), tarsus 11.9-12.9 

 (12.4) mm. 



Resident. Tropical lowlands from the Canal Zone (Frijoles, Gatun), 

 east through eastern Province of Panama (La Jagua, Chepo) to 

 eastern Darien (Garachine, El Real) ; on Cerro Pirre to the lower 

 Subtropical Zone (Cana) ; on the Caribbean slope from eastern 

 Colon (Colon, Portobelo) to western San Bias (Mandinga). 



It is probable that it ranges to eastern San Bias as it is found in 

 northern Choco in Colombia where it has been taken at Unguia.
