330 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



bird common in the northern end of the mountain forests of the 

 Azuero Peninsula, where it ranged from 450 to 900 meters. Farther 

 south in this mountain area C. O. Handley, Jr., collected a male, 

 February 13, 1962, at 1200 meters on Cerro Hoya. Salvin received 

 specimens in the early collections of Arce from Laguna de Castillo 

 and Santa Fe on the Pacific side of Veraguas. In March 1951, I 

 found these birds fairly common at 750 meters on the slopes of La 

 India Dormida above El Valle, and also in the higher forests of 

 the southern side of Cerro Campana at 850 meters. East of the 

 Canal Zone we found them in March 1949, on Cerro Azul, and 

 in 1950 on Cerro Chucanti, where they ranged lower at 200 to 300 

 meters elevation. On Cerro Mali and Cerro Tacarcuna they were 

 common. Females collected here on March 18, 1950, were about 

 to lay. 



On the Caribbean side in Bocas del Toro, Dr. Galindo collected 

 several at 725 meters in the mountain forests on the head of the Rio 

 Changuena in September 1961. Others were taken earlier by Kennard 

 in 1926 and by Wedel in 1928 on the mountain trail leading from the 

 Chiriqui Lagoon toward Boquete. In the early collections of Arce 

 specimens came from Calovevora in northern Veraguas. In February 

 1962, I found them common at 475 meters on the head of Rio Guabal 

 in northern Code. 



There is no further report at present on this slope west of eastern 

 Comarca de San Bias, where Wedel collected specimens at Perme and 

 Puerto Obaldia, and I secured an adult male at Armila and an im- 

 mature on the ridge southeast of Puerto Obaldia in February 1963. 



Beyond Panama this race ranges through the Caribbean slope of 

 Costa Rica and Nicaragua to eastern Honduras. Those of the Isthmus 

 agree in size and color with those of Costa Rica, the type locality. 



Aldrich recorded males of this form in display flight "moving very 

 slowly and evenly through the air with rapidly vibrating wings which 

 produced a distinct humming sound, and with white throat-patch 

 pufifed." On one occasion this slow display flight continued for a 

 distance of 15 meters, accompanied by small explosive sounds as- 

 sumed to have been made by the wings. 



I have found them indifferent to the usual sounds used to attract 

 other birds. Occasionally I have seen them moving with groups of 

 forest birds, but usually they are alone and may be rather secretive. 

 Stomachs examined held seeds, bits of fruit skin, and in one, two 

 small drupes. 



As yet there is no record of nesting of this race.
