Fourteen skins. 

 (Underwood in lift.) : Pozo Pital, San Carlos, Reventazon. 



This cacique is found only in the lowlands and foothills, but is equally 

 common on both the Caribbean and the Pacific slopes, from sea-level up to 

 not more than 1,500 feet, with perhaps a few straggling higher. They are 

 usually found in the forest, although at times frequenting scattered trees 

 in pastures, the edges of the forest and banana plantations. They have 

 a weak, rather musical note, which is often uttered as the birds, in small 

 bands, are feeding or flying about among the trees. I have never seen 

 the nest.
