It is in the warmer parts of South America that these birds reside, in bushy places on the sides of the rivers. 

 They are sedentary, generally in small flocks of ten or twelve, dispersed in the neighbouring shrubs, on which they 

 are constantly on the move, sometimes leaping from branch to branch, or hopping about on the ground round the stems 

 of the thorny shrubs, which they seem to prefer to other kinds ; these they search for minute insects and seeds. When 

 perched, they erect their crests, and at the same time utter loudly without interruption a varied note.

Bill short, straight, triangular, and bare at the base, with the culmen straight to the tip, which is 

 entire and acute ; the nostrils basal, lateral, and membranous, with the opening longitudinal and narrow. 

 Wings moderate and rather pointed, with the first quill shorter than the second and third, which are 

 the longest. Tail moderate, even, and rounded on the sides. Tarsi strong, the length of the middle 

 toe, and covered in front with broad scales. Toes moderate and strong, with the lateral toes equal, and 

 the outer one united at its base ; the hind toe rather shorter than the middle toe, and strong ; the claws
