Dr. Cooper characterizes this as a li\-ely and familiar songster. It arrives 

 he states, at San Diego ahout April 10, and reaches Puget Sound toward the 

 middle of May, occupying nearly all the intermediate country throuohout 

 the summer. It frequents the deciduous trees along the borders of streams 

 and prairies, coming into gardens and orchards with familiar confidence 

 wherever cultivation has reclaimed the wilderness. Like its Eastern proto- 

 type, Its cheerful and varied song is heard all day long until quite late in the 

 autumn. They too build their nests in the shade-trees of the parks of busy 

 cities singing ever Mieir delightful strains, unconscious of the busy and noisy 

 crowd that throngs the neighboring streets.
