three or four seconds, a loud, hollow chirrup, and at times a violent 

 scolding cry, several times repeated. If the bird finds himself approached, 

 he immediately springs to the ground and runs off with amazing rapidity 

 to a safe distance. Then he again ascends a bush and resumes the angry 

 note. Three or four times I have seen one raise itself from the ground, 

 and fly several yards with a low feeble flight ; but whenever I chanced to 

 come on one in an open place I found that I could overtake it running, 

 without the bird being able to raise itself They often fly down from a 

 bush, but always ascend it by hopping from branch to branch. 



"The nest is built in the centre of a bush, from four to six feet above 

 the ground ; it is domed, has a small entrance, and is constructed entirely 

 of dry hair-like grass. They lay four white eggs" (P. Z. S. 1872, p. 543).

This Argentine species was found at San Antonio, at the head of the 

 Gulf of San Matias, by Mr. James L. Peters. He states that it is similar 

 to the preceding species in attitude and manner of carrying the tail when 

 running, and is wholly terrestrial. It differs however in lacking the loud 

 cries of the other species.
