from branch to branch much like a warbler or some of the vireos, and 

 usually has its tail considerably spread, which distinguishes it at once 

 by its greater length and blackness. This species is also usually seen 

 farther away from creeks and streams than the other, sometimes high up 

 on the crest of a ridge far from any water, a situation in which I have 

 never seen aureatus.

 11 Only one specimen was obtained, and to the best of my recollection 

 only two or three others were seen. They were observed among the tree- 

 ferns in a deep ravine at Chatham Bay." (Townsend, Bull. Mus. Comp.

Mr. Cherrie first took this species at Jimenez in 1891 (Expl. Zool. en 

 C. R. 1893, 32) and again in Terraba in 1892. These are theonly published 

 records for its occurrence in Costa Rica, except those given by Mr. Ridg- 

 way in his "Birds of North and Middle America." 



The bird is sparingly distributed over the lowlands of both the Caribbean 

 and Pacific, at least the southern part of the latter, from Pozo Azul 

 southward. I took it in Talamanca and at Guapiles, the extreme portions 

 of the Caribbean lowlands, and also at Pozo Azul and Buenos Aires. 



It is not a denizen of the heavy forests, but frequents the low tangled
