found in the eastern Serrania de Maje. In eastern Darien it is common 

 on Cerro Pirre and Cerro Tacarcuna. There are 2 records from Cerro 

 Sapo on the Serrania de Sapo, on the Pacific side east of the Gulf of 

 San Miguel. On the Caribbean side, H. von Wedel collected several in 

 the hill country of San Bias back of Puerto Obaldia (Griscom, Bull. 

 Mus. Comp. Zool., vol. 72, 1932, p. 370). On March 23, 1949, I shot 

 a pair from high tree tops at Cerro Azul; they were moving actively 

 through the branches with other birds, and were very near breeding. A 

 female taken March 17, 1950, at Cerro Chucanti, Panama, was laying. 

 Ridgely (in litt.) observed a bird carrying nesting material on the 

 Pipeline Road, Canal Zone, on April 23, 1976.

The Rufous-winged Tanager is an uncommon and little known 

 species that inhabits humid forests and forest borders. It seems to be 

 very localized, and has been reported from a variety of elevations, from 

 the lowlands, where Benson took 1 in the Madden Forest in the Canal 

 Zone, on August 8, 1931, through the foothills on the Caribbean slope 

 (300-900 m) (Ridgely, 1976, p. 319), and the mountains of Chiriqm 

 and Veraguas (Griscom, Bull. Mus. Comp. Zool., vol. 78, 1935, p. 374). 

 Ridgely (op. cit.) feels, however, that it is primarily a bird of the foot- 

 hills. H. von Wedel (Peters, Bull. Mus. Comp. Zool., vol. 71, 1931, p. 

 341 ) collected a female on the Boquete Trail in Bocas del Toro, but the
