Carriker : List of the Birds of Costa Rica. 387 



Odontopkorus castigatus Hangs, Auk, XVIII, 355 (Divala, Chiriqui [Brown]); 

 Auk, XXIV, 1907, 291 ( Boruca and El Pozo de Terraba [Underwood]). 



Bangs Collection: Sabanilla (Underwood). 



Carnegie Museum : El Pozo de Terraba, Boruca (Carriker). Three 



skins. 



Specimens from El Pozo compared with the type from Divala, 

 Chiriqui, were found to agree perfectly, while the same birds when 

 compared with O. marmoratus (from which it was separated) were 

 found to be very different, and I see no reason for placing this species 

 under the synonymy of O. marmoratus as was done by Messrs. Salvin 

 and Godman. 



It is found only in the southwestern portion of Costa Rica, occupy- 

 ing the Pacific lowlands, up to about 2,000 feet, from Chiriqui north 

 to Pozo Azul, and perhaps a little farther. It is strictly a denizen of 

 the forest and prefers the thick jungle, wild plantains, and tangled 

 undergrowth to the more open forest. They are almost always to be 

 seen in small coveys, and when flushed usually alight in the low trees 

 and sit perfectly still for some time before flying off again.

A female from Talamanca has a much brighter rufous pileum than 

 all the birds from northeastern Costa Rica, which have the crest 

 feathers shaded with dusky towards the tips. This may be due to age, 

 for otherwise they appear the same. An immature female from Rio 

 Sicsola is quite different from the adult, as follows : the tertials, 

 scapulars, and interscapular region broadly marked with black sub- 

 terminal bars on each feather, the black bars bordered on either side 

 by a narrow bar of buffy or pale rufous ; only the middle of the breast
