Carriker : List of the Birds of Costa Rica. 649 



This curious little species ranges over the whole of the Caribbean 

 lowlands up to 3,000 feet (rare above 2,000) and over the Pacific 

 lowlands and foothills from the Gulf of Nicoya southward. I have 

 seen no record from Guanacaste or the Nicoya peninsula. It is found 

 in the heavy forest and is always seen busily climbing about on the 

 tree-trunks and large limbs in search of insects. It usually keeps 

 well up in the trees, and is quite solitary in its habits, even two 

 birds of the same species being rarely seen in company. I found a 

 single nest of the species on the northern slope of the Volcan de Tur- 

 rialba at about 2,000 feet, which was taken on April 17, 1903, and 

 contained two eggs with the incubation far advanced. The nest was 

 in a natural cavity on the side of a tree, the entrance being secured 

 through a small crack, while the nest itself was a loose mat of black 

 rootlets about one quarter of an inch in thickness. The eggs are 

 pure white, long, and bluntly pointed, and measured 12 X 19 mm.

Differs from D. a. anabatina Sclater in being darker and more 

 olivaceous. Pileum olive-brown, nearly concolorous with back, with 

 scarcely a trace of the rufous so prominent in D. a. anabatina ; tips 

 of primaries blackish-sooty instead of grayish-sooty ; tail darker and 

 richer chestnut, with prominent blackish tips which are wanting or 

 obsolete in true anabatina ; the buffy-ochraceous of the throat darker 

 and intermixed with grayish-olive (immaculate in D. a. anabatina) ; 

 bill much darker, maxilla decidedly blackish. Measurements of 

 type: length, 218 ; wing, 100; tail, 80 mm.
