 They are tame and rather stupid, like all of the genus, and easily 

 approached.

Mr. Ridgway has recently separated the southern birds from those 

 of Guatemala and southern Mexico (the type locality) on the ground 

 that they are darker, have the wings browner, and are on the whole 

 much less ochraceous. The large series of Costa Rican specimens 

 which I have examined bears out these differences, and it seems to be 

 a well-marked race. 



The species is found fairly commonly (as ant-thrushes go) over the 

 northern half of the Caribbean watershed from an altitude of about 800 

 feet up to 3,000 or 4,000 feet. It is also very sparingly found in the 

 southwestern Pacific lowlands, there being one record from Pozo Azul 

 de Pirris, one from Rio Naranjo (Pozo del Pital) and one from El 

 Pozo de Terraba. I did not find the bird in southeastern Costa Rica, 

 nor are there any records from that region. It is found in the thicker 

 parts of the forest, especially where there are few large trees and much 

 undergrowth and vines. They are arboreal in their habits, but do not 

 go high up in the trees.
