eastern half of the state. There are three probable records 
of its occurrence in Lorain county.* In the rougher parts of 
the state this warbler is to be found in the gorges well 
grown with brush and trees. It seems partial to the steep 
hillsides in such localities. 
The first appear in southern Ohio during late April or 
early May, and return south late in September.

While this species seems to be more numerous than the 
last, it is by no means common anywhere in the state. It 
does not remain to breed, but passes north of our border. 
During their migrations these birds are to be found on or 
near the ground, rarely mounting into the lower branches 
of the trees. They seem to prefer brushy tangles within
