BIRDS OF THE REPUBLIC OF PANAMA PART 4 



this race or an intermediate form from Cerro Jefe, eastern Province of 

 Panama, where D. Hill and Ridgely found it several times between 900 

 and 990 m (Ridgely, 1976, p. 303). 



In my few encounters with this species in Darien it has been in 

 flocks moving through the undergrowth or the lower tree crown. 



This form has been given specific rank by some authors. It does not 

 occur on the Cerro Pirre range, where its place may perhaps be taken 

 by B. melanogenys ignotus.

Resident. Fairly common in the lower highlands of Chiriqui and 

 also known from the foothills of Veraguas and Herrera (Cerro Mon-

 Rica. Other races are found in Mexico, through Middle America, and 

 in South America east of the western Andes of Colombia to southern 

 Brazil, Bolivia, Paraguay, and northern Argentina. Monniche col- 

 lected this race on the Volcan de Chiriqui between 1710 and 1800 m
