86 Mr. C. H. B. Grant on Birds collected in Argentina , 
is great similarity in the general tone. When the plumage 
becomes worn the birds have a much more barred appear¬ 
ance on the upper parts. 
Both the February and March adults are moulting. 
The young bird differs from the adult as follows : “ Above 
nearer blackish brown, finely and regularly barred ; below, 
from chin to vent crossed by narrow wavy lines; more or 
less distinct individually." 
A common species and remarkably tame and confiding; 
in call, actions, and habits it resembles the European Wren, 
but carries the tail horizontally. 
It usually nests in holes or crevices in the trees, the nest 
being composed of a few sticks and lined with feathers ; 
eight eggs appear to be the full clutch.
