4l6 BIRDS OF THE REPUBLIC OF PANAMA PART 3 



the Vermilion-crowned Flycatcher, where the two live peacefully 

 even though their homes may be only a few meters apart. 



In Panama the nesting season begins in February and continues 

 through May. 



Skutch writes (loc. cit., p. 411) that the usual set is of three eggs, 

 occasionally two, and rarely four. The color is "dull white, speckled 

 and coarsely blotched with pale lilac and shades of brown, chocolate 

 and burnt umber." In a series the measurements ranged from 20.6- 

 25.0x15.9-17.5 mm. with the average for S3 eggs 23.3x17.0 mm. 



The female incubates alone, calling and singing regularly in the 

 nest, with the male resting near. When the young appear, the male 

 assists in feeding them. Young call frequently and in noisy manner 

 in the nest. Skutch noted them in family groups until September 

 and October, when apparently the young may separate in pairs.

Measurements. — Males (10 from Darien and northwestern Co- 

 lombia in Choco and Cordoba), wing 84.0-88.1 (86.0), tail 65.6-70.8 

 (68.5), culmen from base 14.1-16.7 (15.3), tarsus 18.2-18.9 (18.6) 

 mm. 



Females (10 from Darien and northwestern Colombia in Choco 

 and Antioquia), wing 78.2-83.6 (80.7), tail 60.6-68.7 (63.5), culmen

Resident. Found locally in the Tropical Zone through Darien and 

 eastern San Bias. 



This race is less abundant than the western one because of the 

 forests that cover most of Darien. It is found mainly along the 

 streams in the larger valleys, ranging out as the land is cleared for 

 planting and for pasture. Habits and mannerisms are those described 

 for the nominate race. In eastern San Bias to date it has been re- 

 corded only at Perme. In Darien, at Jaque I collected one from a 

 high perch in an open pasture grown with guayaba bushes. Near 

 the mouth of the Imamado, on the upper Rio Jaque. I found a pair 

 over the river at the border of a small clearing. Near the mouth 

 of the Rio Paya in the Tuira River Valley they came to feeding trees
