before encountered, so procured it, and searched for more, but did not 

 find any. It appears to resemble the next species [tnarithna] closely, 

 and is probably similar in its habits." (Ibis, p. 28, 1897.)

Mr. Peters states that this species was "not uncommon in the vicinity 

 of Huanuluan in the more brushy locations. It appears to be migratory. 

 The first bird seen was on September 11... fledglings were observed 

 on several occasions during November and December 3 a nest was 

 found which probably represented a second brood. It was placed in a 

 thick bush, a very bulky structure lined with feathers of Calopezus elegans 

 and containing three eggs white with some rusty spots at the larger end."
