Carriker : List of the Birds of Costa Rica. 601 



Carnegie Museum : Carrillo, El Hogar, Cuabre de Talamanca 



(Carriker). Six specimens. 



Confined entirely to the Caribbean lowlands and foot-hills, below 

 2,000 feet. It is quite a rare bird in Costa Rica, and not often taken. 

 They inhabit the thick jungle in places where there are not many 

 large trees to keep out the sun, permitting the undergrowth to become 

 very dense. I also found them in patches of wild cane along the 

 Sicsola River. They are almost entirely arboreal in their habits, 

 very quiet, and not easily alarmed ; and, if they have any call, I 

 never heard it.

This ant-thrush is fairly common in most of the lowlands of both 

 the Caribbean and Pacific, up to about 1,500 feet. Like the pre- 

 ceding species, it is not found in heavy, dark forest, but in wild cane 

 and thick jungle, with only scattering trees here and there. This 

 species is also very fond of the large patches of " wild plantains " so 

 common along the streams of the lowlands and in many places in the 

 forest on the Caribbean side. It is very tame, almost entirely arboreal, 

 and has a rather harsh call, not often heard. It is almost always 



seen in pairs.
