The Towhee Bunting is a common summer resident in Illinois 

 and Wisconsin, frequenting the hedges and thickets, from April until 

 October (earliest Chicago record, March 16). The characteristic note 

 of this species is a loud, clear chee-we or che-wink. 



It breeds from the latter part of April until July. The nest is 

 built on or near the ground and is composed of leaves, strips and 

 shreds of bark, etc., and lined with fine grass. The eggs are from 

 3 to 5, white or pinkish white or buff white, speckled all over with 

 brown, occasionally showing a few blotches at the larger end; size 

 about .95 x .71 inches.
