The Clay-colored Sparrow is not uncommon during migrations 

 and may be considered a summer resident in northern Illinois. It 

 is more common in Wisconsin. Nelson considered it " a rare summer 

 resident about the borders of prairies. Specimens are in Mr. Holden's 

 collection taken near Chicago." (Birds N. E. 111., 1876, p. 108.) Mr. 

 O. C. Poling met with this species occasionally during migrations 

 near Quincy, 111., and says: " Early in May, 1887, I collected a num- 

 ber of specimens and found them quite common in pasture and stub- 

 ble fields near the city." (The Auk, 1890, p. 242.) 



Regarding its occurrence in Wisconsin, Kumlien and HoUister write : 

 "An irregularly distributed summer resident from the southern part 

 of the state northward. * * * * * Has been taken nesting at Lake 

 Koshkonong, where it occurs as a regular summer resident. More 

 common about Stevens Point than any other locality we know of." 

 (Birds of Wisconsin, 1903, p. 100.) 



The nest is in low bushes or on the ground, and is composed of 

 grass. The eggs are 3 to 5, pale greenish blue, speckled and marked 

 chiefly at the larger end with dark brown, and measure about .66 

 X .50 inches.
