370 BIRDS OF THE REPUBLIC OF PANAMA PART 2 



Resident. Fairly common in the mountains of Chiriqui and 

 Veraguas, in the Subtropical and upper Tropical Zones; recorded 

 to date only from the Pacific slope. 



In western Chiriqui I found this species on the lower slopes of 

 Cerro Pando beyond El Volcan, at 1,350 meters, where on March 8, 

 1954, 2 fed quietly at the flowers of a low shrub under cover of the 

 forest. Occasionally the 2, both immature males, searched the same 

 spike of blossoms, usually amicably. Once or twice they turned 

 toward one another in threat, moving up and down for a meter or less, 

 but made no other demonstration. Others were seen here searching 

 flowers on the forested slopes to elevations of 1,600 meters. The 

 following year at Santa Clara I found 2 juveniles at 1,150 meters in 

 an open pasture beside the brush-grown banks of the Quebrada 

 Santa Clara, where they rested in the sun on dead branches in a 

 small tree. Elsewhere, they have been taken at Quiel, and at other 

 localities in the Boquete region, to 1,750 meters elevation. 



In the mountains of Veraguas, Arce found them more common 

 and forwarded series of specimens to Salvin from Castillo and the 

 Cordillera del Chucu. A male in our collections was taken by Heyde 

 and Lux at Chitra in July 1888. 



In small size this species suggests the still more tiny Selasphorus 

 of the same mountain area, but in action usually Philodice bryantae 

 is more active in movement. 



Lawrence named this beautiful species "in compliment to Mrs. 

 Bryant, the widow of my friend, the late Dr. Henry Bryant, of 

 Boston."
