Hudson says: "This little bird is very common in the woods of Pata- 

 gonia, goes in pairs, and builds a large nest of sticks with a narrow long 

 entrance, and lays four pointed white eggs; but there is as little in its 

 habits or language, as in its form or color, to distinguish it from many 

 other members of the extremely monotonous tribe to which it belongs." 

 (P. Z. S. 1872, p. 543.)

E. W. White, speaking of its occurrence at Cordova, Argentina, says : 

 "The abode of this bird seems to be the highlands, where it loves to fre- 

 quent small shrubs and brushwood, into the deepest shade of which it 

 penetrates. When startled, its flight is quick and dipping from one bush 

 to another, uttering meanwhile a pretty trilling cry." (P. Z. S. 1883, 

 P- 39-)
