278 BIRDS OF THE REPUBLIC OF PANAMA PART 2 



(Boquete Trail at 1,500 meters, Almirante, Rio Changuena) ; northern 

 Veraguas (Calovevora, Belen) ; northern Cocle (Tigre, on the head of 

 Rio Guabal) ; western Colon (Chilar, on the Rio Indio) ; San Bias 

 (Perme, Armila, Ranchon, Puerto Obaldia). On the Pacific side 

 recorded on Cerro Campana (900 meters) in Western Province of 

 Panama, and in the mountains of Darien (Cerro Sapo, Cerro Pirre, 

 Cerro Mali, La Laguna, Cerro Tacarcuna). 



Salvin and Godman (Biol. Centr.-Amer., Aves., vol. 2, 1892, p. 315) 

 include Chitra, a locality on the southern slope of the mountains in 

 Veraguas, but I believe this may be in error, as in my examination of 

 specimens from their collection in the British Museum I have not 

 found any from that locality. My only certain record for the Pacific 

 slope of western Panama is of 1 that I saw March 11, I960, at 800 

 meters in woodland on the head of the Rio Escarrea, above Buena 

 Vista, Chiriqui. An important recent record is of a female collected 

 on Cerro Campana, July 9, 1966, by Storrs Olson. Others were taken 

 here by G. V. N. Powell, October 30, 1966. 



This is another species of heavy woodland, found usually in under- 

 growth in such shadows that often only the white tail tip is clearly seen. 

 These hummingbirds decoy easily, but hover for inspection at a dis- 

 tance of several meters, often partly concealed beside the trunk of a 

 tree. The legs are long and strong, and the whole body is strongly 

 muscular. They feed regularly at the angular flowers of heliconias at 

 which they cling, often rather awkwardly, while the curved bill is 

 thrust into the blossoms. At other times they hover while gleaning tree 

 trunks, usually near the ground. The tongue which extends to the end 

 of the bill has the same curvature, so that it lies smoothly in the groove 

 of the lower mandible. 



When Gould named this bird in 1868 in honor of Osbert Salvin, 

 with regard to locality he said only that he had 3 specimens from 

 "Veragua." In an earlier account under the heading Entoxcres aquila 

 in his Monograph of the Trochilidae (vol. 1, November, 1851, pi. 3, 

 with text) he said that at the time 2 specimens were "all that is known 

 of this rare and singular Humming Bird ; of these one is in the Lod- 

 digesian Collection, the other in my own. . . . My own specimen was 

 . . . sent from Veragua in Central America by the well-known botanical 

 collector M. Warszewiez, who, while crossing from Bocco del Toro 

 on the Atlantic side of Panama to David on that of the Pacific, was 

 induced to deviate in search of novelties to the Rovalo peak, where his 

 labours were rewarded by the discovery, among other interesting ob- 

 jects, of this very curious bird." The old trail that crossed from the
