 This species, referred by early writers to H. perspicillatus of Panama, 

 is easily distinguished from that bird by the ruddy flanks and under tail- 

 coverts. Its Costa Rican range covers the whole of the Caribbean 

 lowlands from sea-level up to about 800 or 900 feet. It scarcely 

 gets into the foothills at all, but keeps to the level lands below. The 

 upper edge of its range slightly overlaps the lower portion of that of 

 H. dives, the two birds having been taken in the same locality in the 

 lowermost portion of the foothills. It frequents the portions of the 

 heavy forest which are least filled with undergrowth, and is usually 

 found alone, or sometimes in pairs. It is not such a suspicious bird 

 as Formicarins or Gymnocichla, and when suddenly flushed will fre- 

 quently fly up on a log or low branch and sit perfectly quiet. The 

 call is very similar to that of Formicarius and Myrmeciza, except 

 that it is softer and weaker, and is very seldom repeated more than 

 three times (that is, three notes altogether). Neither is it so much 

 addicted to calling as is Formicarius, and will not respond so readily 

 to the imitation of its note by the collector.
