Unlike most of the sparrows the fox sparrow displays an ability 

 to let his notes drop into one another by a quick flexible slide, 

 usualh' accompanied by a slight change in timbre, which is the 

 characteristic of the warbling birds such as the vireos — in this 

 respect he surpasses all of his race that I have ever heard except 

 the rose-breasted grosbeak and the cardinal. 



One of the most interesting circumstances connected with the 

 three occasions when I have heard the full song w^as the fact that 

 each time opportunity was abundantly given for direct comparison 

 of the fox sparrow with the strongest singers of the early spring. 

 Not only the song, vesper, field and tree sparrows and juncos were 

 singing, but tufted titmice, Carolina wrens, meadow-larks, card- 

 inals, bluebirds and robins ; with all of these the fox sparrow 

 held his own. He quite overpowered the other sparrows by his 

 vocal strength and surpassed the wren and titmouse in musical 

 form. Only the meadowlark, robin and cardinal were noticably 

 louder and of all the singers only the cardinal, meadowlark, wren 

 and bluebird were comparable in sweetness and richness of tone. 

 The bluebird came the nearest in qualitj-. One of them perched 

 not thirty 3'ards from the sparrow and sang vigorously as if in 

 answer or rivalr}'. The two songs were not wholh' unlike in 

 warbling character and bore much resemblance in timbre but the 

 sparrow was undeniably sweeter, more sustained, more elaborate 

 and more vivacious. 



As. compared with the wren or cardinal the sparrow was less 

 round and clear in his tones but was equall}' spirited and music- 

 all}' much more interesting. To match him in all respects one 

 would have to induce a rose-breasted grosbeak to sing the vesper 

 sparrow's theme : to surpass him one would have to call upon one 

 of the major singers, the thrasher, the bobolink or the thrushes.
