Not very common spring and fall migrant in Middie Ohio. Mr. 
Langdon gives it as quite common in the fall, in the vicinity of Cincin- | 
nati. Summer resident in Northeastern Qhio, 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 (1. c. Fam. Vis.) that it remains to 
breed in considerable numbers in Northern Obio, and that he found the 
‘nest in an almost impenetrable thicket, placed in the fork of a slender 
shrub, four or five feet from the ground,” and that it contained three 
eges, nearly white. It has since beea found to breed regularly.
