562 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



I have found them mainly in the tops of undergrowth in the forests, 

 where they moved quietly, usually alone, occasionally in company 

 with small groups of other birds. In Chiriqui and in the Province of 

 Los Santos in the Azuero Peninsula they were mainly in heavier 

 stands of forest, but in the lowlands were encountered also in more 

 open areas. At La Jagua they lived in somewhat scattered under- 

 growth through the narrow lines of trees along the borders of the 

 marshes. They came occasionally to eat drupes of shrubs and trees, 

 and also plucked insects from leaves. It was common for one to rest 

 quietly for several minutes, usually on some sheltered perch, when 

 it suggested an Einpidonax or other small species of the family. In 

 my experience they were silent. 



On Isla Verde one ranged near the shore in the border of man- 

 groves. In the forests on Isla San Jose they inhabited the stands of 

 tall trees along the streams. 



Little is known of their nesting. A male, collected May 19, 1953, 

 at Sona, Veraguas, was in breeding stage. Another male, near breed- 

 ing, was collected in the undergrowth in deeply shaded woodland on 

 Isla Urava, near Isla Taboga, December 26, 1955. J. Stuart Rowley 

 (Condor, 1962, pp. 256-257, fig. 1), in Morelos, southern Mexico, 

 found the nests of the closely related Myiopagis v. placens through 

 watching and following females carrying nesting material. The nest, 

 from his description and a photograph was a shallow cup woven of 

 vegetable fibers, with the bottom and lower sides so thin that the 

 contents were visible from the sides. Nests were placed in terminal 

 crotches in the tops of low trees a few meters above the ground. 

 His illustration shows eggs with a white or whitish background 

 "handsomely marked with heavy lilac and chocolate brown colored 

 streaks and blotches over most of the surface." Three nests found 

 in June and July held two eggs each. In one set these measured 

 18x13 and 17x12.5 mm. and in another, 17.8x13 and 17.6x13.1 

 mm. Dr. Eisenmann has brought to my attention description of an- 

 other set of eggs of the race placens from British Honduras (Oates 

 and Reid, Cat. Birds Brit. Mus., vol. 3, 1903, p. 196, pi. 4, fig. 16). 

 These, collected by F. Blancaneaux, are described as "cream-coloured, 

 streaked and spotted, more densely at the broad end where the mark- 

 ings form a wide zone, with purplish brown and deep lavender." 

 The two eggs in this set, said to have been taken in May, measure 

 18.0 X 13.7 and 18.2 x 12.9 mm. 



The record for Garachine, Darien, listed above is a specimen in the 

 Academy of Natural Sciences in Philadelphia, collected in April 

 1941, on the Fifth George Vanderbilt Expedition.
