others at Tacarcuna Village (570 m) and on Cerro Pirre at the head of 

 the Rio Seteganti (450 m). The 3 birds 1 took at Cerro Pirre all had 

 the tail feathers damaged or cut, as though they had been feeding in 

 "cana brava" (Bactris minor), a small palm heavily armed with long 

 slender spines. The male I collected at Tacarcuna Village on March 9, 

 1962, was in breeding condition; its song was clear and sweet with 

 robin tones, but with many notes that suggested an oriole. 



The only other indications of the breeding season of this race in 

 Panama comes from Bangs and Barbour (Bull. Mus. Comp. Zool., vol. 

 65, 1922, p. 221), who reported 3 adults and 2 "spotted young" taken 

 at the headwaters of the Rio San Antonio on Mt. Sapo in April 1922. 

 A heavily spotted immature in the Smithsonian collection (USNM no. 

 427026) was collected by Carriker in Colombia at Villa Arteaga, Antio- 

 quia, on May 6, 1950.
