This Tangara is confined in Costa Rica to the northeastern foot-hills 

 of the Caribbean slope, from the Reventazon northward as far as the 

 Sarapiqui River (so far as is now known), at. an altitude of between 

 1,000 and 2,000 feet. It is most abundant in the gorge and along the 

 slopes of the Rio Sucio, whence nearly all of the known specimens have 

 come. It is most in evidence in August and September, feeding on a 

 certain fruit there in company with T. icterocephala and several species 

 of Euphonia.
