86 ^Ir. C. H. B. Grant on Birds collected in Argentina, 



is great similarity in tlie general tone. When the plumage 

 becomes worn the birds have a much more barred appear- 

 ance on the upper parts. 



Both the February and Marcli 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.
