This handsome little species is found throughout the highlands, as a 

 rule above 2,000 feet, but a few stragglers have been taken below that 

 elevation on the Caribbean slope. It is not common above 7,000 feet, not 

 being found in company with the mountain species, E. atriceps. It has 

 also been found in the Dota Mountains, but was not taken by Underwood 

 in the mountains of extreme northern Costa Rican or in the Cerro de Santa 

 Maria. It is a woodland species, inhabiting only the heavy virgin forest, 

 where it is always seen in the low trees and shrubbery. The birds are 

 very tame and unsuspecting, permitting themselves to be approached 

 closely without showing signs of fear. 



I took one nest of this bird at Juan Vinas, May 8, 1907, containing three 

 fresh eggs. -The nest was constructed almost entirely of moss, and lined 

 with fine fibres of weeds. It was placed on the broken and jagged end of a 

 fallen tree, about ten feet from the ground, in the midst of the forest. The 

 eggs are rich cream-color, thickly speckled and blotched with light chest- 

 nut-rufous about the larger end, and sparingly over the remaining surface 

 Measurements: 19X14, 19X14, and 19X14 mm.
