• The habits of the Harris sparrow are largeh' common to those of 

 the genus. In describing them Colonel Goss says: "The birds 

 inhabit the thickets bordering streams and the edges of low wood- 

 lands. They are usually met with in small flocks. A favorite resort 

 is in and about the brush heaps, where the land is being cleared. 

 They seldom mount high in the trees, but keep near the ground, 

 upon which they hunt and scratch among the leaves for seeds and 

 insect life. 



" They commence singing early in the spring, and upon warm, 

 sunshiny days their song can be heard almost continually, as one 

 after the other pours forth its pleasing, plaintive, whistling notes, in 

 musical tone much like the white-throated sparrow, but delivered 

 in a widely different song." Prof. Cooke says that in addition to 

 their albicolUs whistle they have a 'queer, chuckling note.' (See 

 Cooke on "Distribution and Migration of Zonotrichia querula," 

 The Auk, i. 332.)
