Resident. Locally fairly common near the sea on the Pacific slope 

 from Los Santos (Tonosi, Pedasi) and Herrera (Rio Santa Maria, 

 Monagrillo) on the eastern side of the Azuero Peninsula, through 

 Code (Aguadulce), the eastern and western segments of the Prov- 

 ince of Panama (Bejuco, Rio Juan Diaz, La Jagua, Chiman, Maje) 

 and the Canal Zone (Miraflores Locks), to Darien (Garachine). 



This bird was reported first in Panama by Hallinan (Auk, 1924, 

 p. 319) from one that he collected October 3, 1915, near the mouth 

 of the Rio Juan Diaz, east of Panama City. The next records were 

 of three taken by R. R. Benson near Aguadulce, Code, in September 

 1925, the series from which Griscom named the race. The Fifth 

 George Vanderbilt Expedition in 1941 collected one near Garachine, 

 Darien (Bond and de Schauensee, Acad. Nat. Sci. Philadelphia, 

 Mem. 6, 1944, p. 35) which to date is the only specimen record for 

 that province. 



The report by Chapman from Barro Colorado Island (Tropical Air 

 Castle, 1929, p. 405 ; Life in Air Castle, 1938, p. 235) under the name 

 Dendroplex picus "panamensis" (a nomen nudum) probably refers 

 to observations he made during a visit to La Jagua in company with 

 Karl Curtis, as this woodhewer is not known in the Canal Zone north 

 of the Miraflores Locks. 



After field experience with several races of this species in northern 

 South America where I saw them in partly wooded pastures, dry
