The December and February adult birds are worn and the 

 March bird is moulting. 



The two May females are in the new dress and are much 

 browner than those in worn breeding-plumage. 



The young male is rather paler above than fresh-moulted 

 adult females, and is whiter below with more numerous and 

 narrower streaks. 



This is a common resident species at Ajo, where it is 

 called tlie " Canary " or " Yellow House-Sparrow." 



It is very tame and often found round habitations, and 

 has a rather sweet song. 



It usually breeds in the old nests of Furnarius rufus and 

 occasionally under the roofs of outbuildings. The nest is 

 cup-shaped and composed of wool. Eggs were brought 

 home taken at Ajo.

The male is much browner above than the breeding-birds
