Song. "Chewee-chewee-chewee, tira-lira-lira-lee." ^Ir. Davie de- 
scribes the song as a clear, sweet trill, finely modulated, or the song spar- 
row's song reversed. 
Investigation of the food habits of the vesper sparrow by the United 
States Department of Agriculture shows that two-thirds of the food of 
the year is of vegetable matter, the rest being largely insects and spiders. 
In summer the birds eat chiefly insects, especially grasshoppers, beetles, 
cut worms and army worms. In July grasshoppers form nearly half 
of the sparrow's food. Thus we see the vesper sparrow aids the farmer 
in his fight against weeds and insect pests.
