BIRDS OF THE REPUBLIC OF PANAMA PART 4 



found in lowland forest, similar to that in which Dusky Pigeons are 

 found in Colombia. 



This species was previously known from western Colombia and 

 northwestern Ecuador. Haffer (Bonner. Zool. Monog. no. 7, 1975, p. 

 89) records it north to Mutata, Colombia, about 200 km south of the 

 Panama locality.]

Peristera auriculata Des Murs, in Gay, 1847, Hist. Fis. Pol. Chile, Zool., 1, p. 381. 

 (Santiago, Chile.) 



This species is known in Panama from a single immature individual 

 seen and photographed at Coco Solo, Canal Zone, on February 3, 1973, 

 by Ridgely, Eisenmann, J. Gwynne, and C. Leahy. The bird still had 

 scaling on the back and was very tame. It is possible that it escaped 

 from captivity. Normally it is found in the southern Lesser Antilles 

 and most of South America.]
