Resident. Found locally on the higher elevations of Cerro Pirre, 

 Darien. 



This was one of the interesting additions to the birds of Darien 

 in the collections made on Cerro Pirre by E. A. Goldman in 1912. 

 The little known of the bird is found in the brief notes left by the 

 collector. On April 12 he established a camp near the head of Rio 

 Limon at 1,575 meters elevation. His first observation of this trogon 

 was on April 17, when a pair passed through the tall trees near camp. 

 The series of 7 that he collected were taken between that date and 

 April 29, mainly between 1,525 and 1,585 meters, with 1 slightly 

 lower down at about 1,375 meters. He recorded them as having rapid 

 wing strokes, and with flight mainly in a direct line. Those taken 

 were in breeding stage. He mentioned especially their calls, unlike 

 those of other trogons, which varied from cawing sounds, like the 

 utterance of crows, to others that suggested the loud notes of the 

 laughing falcon. 



Griscom's inclusion of this species (Bull. Mus. Comp. Zool., 

 vol. 78, 1935, p. 325) from "Mt. Pirri, Darien (fide Chapman)" 

 probably was based on Goldman's specimens. The summit of the 

 Pirre range has been little visited. The only other record of this 

 trogon known to me from this area is a female in the Gorgas Memorial 

 Laboratory taken by R. Hinds on August 7, 1965.
