FINCHES, SPARROWS, ETC. 337 



As he sits he has a trick of raising his crown every few minutes, 

 calling especial attention to his directive face marking, and the 

 moment he flies his white tail crescent shows conspicuously. 



He is much in evidence, not only from his abundance and his con- 

 spicuous markings but from his musical song, which is heard almost 

 continuously wherever he is found. The song is long and varied and 

 has a purring phrase which is especially characteristic. Like the 

 house finch he sings with fine fervor when dancing before his mate 

 with spread tail and quivering wings.
