These specimens appear to be quite identical with a series 
of twenty-one examples in the National Collection from 
various localities in South America. 
The young bird is distinguished from the adult by the 
rufous margins to the feathers of the crown and the sulphur 
or orange bases to the feathers of the head, also by the 
rufous margins to the upper wing-coverts. 
[This species is resident, but not common. The haunts 
of these birds are invariably along the forest-streams. I 
have never seen them in the open, and I know nothing 
more about their habits.— W. F]
