This is a southern form of C. guatemalensis, distinguished by its 

 smaller size and much more yellowish under parts and under wing- 

 coverts, and is probably confined to Nicaragua, Costa Rica, and 

 Panama, although specimens from northern Nicaragua show signs of 

 intergradation. Costa Rican birds are nearly typical buxans. 



This bird has a very wide range in Costa Rica, being found on both 

 coasts in abundance, and in smaller numbers up over the plateau 

 region, wherever heavy virgin forest is found. It is an extremely 

 hardy bird and very tenacious of life, carrying away with no apparent 

 inconvenience heavy charges of shot at close range. It is usually 

 seen in pairs, each pair seeming to occupy a certain small district, into 

 which no others intrude.

In the Catalogue of the Birds of the British Museum, Hargitt 

 mentions the fact that Costa Rican examples of C. lineatus were not 

 quite typical, but he did not think them separable. I find that all 

 birds from southwestern Costa Rica are very close to true lineatus of 

 South America, some even being indistinguishable from them, but as 

 one goes northward they gradually become intermediates between line-
