Description. Uniform glaucous blue ; wings and tail blackish, the feathers 

 edged with light blue : total length 5-7 inches, wing 2' 9, tail 2 '3. 



Hab. Paraguay, Uruguay, and Argentina. 



This is a rare Finch, and its massive beak and rich blue plumage 

 give to it a highly interesting appearance; but about its habits I have 

 little to tell, for it is essentially a bird of the wild forest, seldom coming 

 near the abodes of man, and being, moreover, shy in disposition, it is 

 difficult to observe, it even in its haunts. It is migratory, and is usually 

 seen singly or in pairs, or in small companies of four or five individuals. 

 The male sings, but his performance is merely a confused medley of 

 chattering notes, uttered in so low a tone that they can scarcely be 

 heard at a distance of twelve yards.
