This bird is very common on the coast of Chile, from the humid forests of 
Chiloe to the desert mountains of Copiapo. In Chiloe it is perhaps the most 
abundant of the land birds ; south of Chiloe I never saw it, although the nature of 
the country does not change them. On the eastern side of the continent, I met 
with this bird only at the Rio Negro, in northern Patagonia. I do not believe 
it inhabits the shores of the Plata, although so common in the open country, 
under corresponding latitudes west of the Cordillera. The Diuca, as this 
Fringilla is called in Chile, generally moves in small flocks, and frequents, al- 
though not exclusively, cultivated ground in the neighbourhood of houses : habits 
very similar to those of the Zonotrichia matutina. During incubation, the male 
utters two or three pleasing notes, which Molina has in an exaggerated de- 
scription called a fine song. In October, at Valparaiso, I found the nest of this 
bird in the trellis-work of a vineyard, close by a much frequented path. The 
nest is shallow, and about six inches across ; the outer part is very coarse, and 
composed of the thin stalks of twining plants, strengthened by the husky calices 
of a composite flower ; this outside part is lined by many pieces of rag, thread, 
string, tow, and a few feathers. Eggs rather pointed, oval, *94 of an inch in 
length ; colour, pale dirty green, thickly blotched by rather pale dull-brown, which 
small blotches and spots become confluent, and entirely colour the broad end.

This Fringilla, which was first brought from Chile, is abundant in the southern 
parts of Patagonia.
