FAMILY TYRANNIDAE 4OI 



The early records of this species were by Arce who sent specimens 

 to Salvin taken near Chitra, Calovevora. and Calobre on the Pacific 

 slope of Veraguas. Three of these from the last two localities are now 

 in the British ^Museum. H. J. \\'atson collected a male at 1220 meters 

 above Boquete, April 19, 1905, and Mrs. M. E. Davidson a male at 

 1524 meters at Chiqiiero, December 17, 1933. and a female at 1615 

 meters at Horqueta above Boquete, February 5, 1934. The Monniche 

 collection in the Field Museum has others from Lerida and Quiel in 

 this same area, and also a male at 1584 meters at Camp Cilindro on 

 the Holcomb Trail in adjacent Bocas del Toro. In February 1955, 

 I collected a male and saw at least two others on the long, forested 

 ridge of Cerro Picacho at 1880 meters west of El Volcan. Others 

 were seen here somewhat lower down on February 7, 8, and 13, 1960. 

 We have one other male, collected by Dr. C. Lynn Hayward above 

 Cerro Punta on March 8, 1962. 



I found them in the high tree crown, moving rather slowly among 

 the leaves, and also coming to a feeding tree. In this, one flew out, 

 seized the small drupes one at a time and then came back to a lower 

 perch to swallow them. Their low calls, heard rather indistinctly, 

 suggested those of the streaked flycatcher, a resemblance heightened 

 by their similarity in movement, but with a confusing suggestion of 

 the Boat-billed Flycatcher because of their yellow breasts and dark 

 backs. 



In Costa Rica, where Skutch (Pac. Coast Avif., no. 34, 1960, 

 pp. 392-395) found them more common, he heard a high, sharp call 

 and a three-noted melodious phrase that resembled a song. They were 

 found in pairs throughout the year. Two nests that he observed were 

 placed in recesses among the mosses and epiphytes abundant in the 

 cloud forest, elevated 20 to 30 meters above the ground. The nests, 

 built by the female alone (though accompanied by her mate), were 

 made mainly of green moss. As they were inaccessible, he made no 

 notes on the eggs or young. 



Though Hellmayr has listed hemichrysus as a race of the more 

 southern M. chrysoccphalns, it differs so distinctly in the brighter 

 yellow of the under surface, without streaking on the breast, even 

 in the juvenile stage, that it is to be treated as a separate species.
