 " Vieill. Gal. I, PL clxvi. 



One of the most beautiful of the birds of western South America, though not abundant in 

 Chile. It is allied to the crested wrens of North America and Europe, and appears to resemble 

 them in habits, living in the forests and subsisting on small insects. 



Lieutenant Gilliss observes of this species: "This is undoubtedly the most brilliant bird of 

 Chile, but is not very abundant. It lives in the vicinity of marshy ground where the typlia 

 angusf'i/oUa grows, on one of the stalks of which its nest is usually constructed. The nest is 

 correctly represented in Gay's Fauna Chilena."
