Not very common spring and fall migrant in Middle Ohio. Mr. 

 Langdon gives it as quite common in the fall, in the vicinity of Cincin- 

 nati. Summer resident in Northeastern Ohio, where it breeds. The 

 Chestnut-sided Warbler is to be found early in May in small numbers in 

 woods, rarely in the gardens of the city. It is one of the most beautiful 

 birds of the family. Mr. Read states (I. c. Fam. Vis.) that it remains to 

 breed in considerable numbers in Northern Ohio, and that he found the 

 " nest in an almost impenetrable thicket, placed in the fork of a slender 

 shrub, four or five feet frum the ground," and that it contained three 

 eggs, nearly white. It has since been found to breed regularly.
