Carriker : List of the Birds of Costa Rica. 761 



Carnegie Museum: Guapiles (Carriker & Crawford), Carrillo, El Hogar, 



Guacimo, Cuabre (Carriker). Thirteen skins. 



This handsome species is found only in the Caribbean lowlands and 

 lower slopes of the Cordillera, from near sea-level up to not more than 

 2,000 feet, but not at all commonly above 1,200 feet. It also inhabits the 

 heavy forest, but is not so shy as Henicorhina and does not creep around 

 amongst the fallen trees and rubbish so much as that bird. It is also 

 a fine songster, possessing a strong clear song of sweet liquid notes, but 

 not of such great range as Henicorhina prostheleuca. 



They are almost always seen in pairs and are fairly abundant in some 

 sections. I found many nests of this bird at Guapiles, Jimenez, El Hogar, 

 and on the Rio Sicsola, all being built of weed-stems, grass, rootlets, and 

 skeletonized leaves, and always entirely lined with soft skeletonized leaves. 

 It is an elbow-shaped structure, usually hung in an upright crotch of some 

 small tree or shrub from five to fifteen feet above the ground, and is usually 

 about ten inches long and with a diameter of three to five inches at the 

 larger end. Two nests taken with fresh eggs were secured at Jimenez, 

 May 9 and 11, and each contained three eggs, which seems to be the full 

 complement for this species. The eggs are pure white, sparingly speckled 

 over the whole surface (more thickly about the larger end) with cinnamon- 

 brown. Measurements of one set: 23X16, 25X16.5 and 24X17 mm.
