FINCHES, SPARROWS, ETC. 365 



Distribution. — Breeds in Transition and Upper Sonoran zones on the 

 Plains and eastern foothills of the Rocky Mountains from the Saskatche- 

 wan soutii to southern Colorado, and from the Missouri west to western 

 Montana ; winters south to Texas and west to Washington ; casually to 

 Iowa and Wisconsin. 



Nest. — On the ground, made at times of pine needles and lined with 

 grass. 



The towhees of the maculatus group are shy birds of the chap- 

 arral, and when caught singing on top of a bush, where you can 

 study the amount of white mixed with the black and brown of 

 their plumage, they are liable to stop short in their song and pitch 

 down to the ground with only an aggravating flash of the white 

 tail corners. And though you wait patiently, all the reward you 

 are likely to get is a nasal ichank or a mewing tow-hee as they rattle 

 the dead leaves, scratching for worms under the dense cover of 

 brush. 



Both their call-notes and songs have a quaint twang that give 

 them peculiar zest. One of the commonest songs in general time 

 and emphasis may be given -dsyang', kit-er-cr.
