This common and familiar little bird was met with oveiywhere, except 

 during the winter season ; and in all wooded localities, with the exception 

 of the higher forests, which it gave up chiefly to 1). axduhoni, was the most 

 abundant and generally distributed member of the family. At Sacramento 

 it was one of the commonest birds, iidiabiting every copse, whether of 

 willow, cotton-wood, or oak ; and throughout tlie Interior it was equallv 

 plentiful in every locality producing a growth of willows or other shrubbery, 

 being most multiplied in the river-valleys or lower canons, and gradually 

 decreasing in numbers toward the summits of the mountains. No difference 

 whatever exists, apparently, between the western and eastern birds of this 

 species.
