p. 160). Carl Kelsey reported it as a tolerably common summer 

 resident in Poweshiek county and W . H. Bingaman writes that 

 he has found one nest, containing four fresh eggs, May 30, 1903, 

 on the ground in a swampy place along King Creek in Kossuth 

 county. I have ob.served the species on very rare occasions in 

 Winnebago county, in summer, but have found no nests, although 

 the species occurs quite commonly during migration. B. H. Wil- 

 son reports the species as a "rare migrant; one shot June 9, 1889, 

 and another May 14, 1892" (Scott).

The Gray-cheeked Thrush is a tolerably common migrant in 

 most parts of the state, usually during the first three weeks of 

 May, but it has been observed as early as April 24 and as late as

 quenting low trees and shrubs. The species resemble the Olive- 

 backed Thrush very closely, but may be known from it by having 

 110 buif ring around eye.
