Irides dark brown; bill, legs, and toes sooty black. 
The September male is somewhat worn and very dark 
above. 
The March birds are all moulting and their new dress is 
more olive above than that of the breeding male; one of them 
is spotted below and is probably not yet fully adult. There 
is a male in Miss Runnacles' collection, taken at Ajo on 
September 27th, which is much worn and very pale below 
and thickly spotted on the under parts except the throat. 
The young male is moulting into the chestnut plumage, 
and most of the new feathers have spots ; in its first plumage 
it was apparently very similar to the adult female. 
The specimen from Bella Vista is rather pale and more 
uniform greyish above than the others : it is undoubtedly a 
male, though it could not be dissected. 
This species is not very plentiful in the Ajo district, 
where it is resident; it frequents, as a rule, the under¬ 
growth in the woods and gardens.
