THE SPARROW TRIBE AND ITS KIN 111 



is bufFy. The tree sparrow has a parti-colored bill, the 

 upper-haJf black, the lower yellow with a black tip, while 

 the chippy has an entirely black bill, and the field sparrow 

 a flesh-colored one. Only the tree sparrow, which is 

 larger than either of the others, although only as large as a

 friendly flocks that glean a comfortable hving from the 

 weed stalks protruding from the snow. Their cheerful, 

 soft, jinghng notes have been likened by Mr. Chapman to 

 "sparkling frost crystals turned to music."

 Cdn-Orda, Cdn-a-da-a, while the New Englanders think the 

 bird distinctly says, I-I-PSa-body, PSa-bod-y, PSa-bod-y-I, 

 extolling the name of one of their first families. You may 

 amuse yourself by fitting whatever words you like to the 

 well-marked metre of the dear, high-pitched, plaintive,
