This species is confined to the southwestern Pacific lowlands and slopes, 

 from Puntarenas southward into Chiriqui. Its habits, habitat, song, and 

 breeding are practically the same as those of its near relative of the Carib- 

 bean slope, R. passerinii. I found the birds breeding at Pozo Azul de 

 Pirris, two nests being taken on May 8, 1902, one set fresh, and the other 

 slightly incubated.

This warbler-like tanager is confined to the foot-hills of the Caribbean 

 slope, from 1,200 to about 2,500 feet. It is most abundant in the northern 

 part of the country, from the Reventazon River northward, and reaches 

 its point of greatest abundance in the vicinity of Carrillo, seeming to 

 thrive better in the very humid conditions which prevail at that point. 

 It is an inhabitant of the heavy virgin forest, keeping well up in the trees 

 like the tanagers and many of the warblers, and seems to be almost if 

 not entirely insectivorous.
