Dr. Wheaton gives this warbler as a “Common summer 
resident.” It is so reported by a few observers well scat- 
tered about the state, but is regarded by most as common. 
only during the migrations. My studies in different parts 
of the state have convinced me that it is to be found breed- 
ing in suitable places over the entire state, but is common 
only locally. It breeds sparingly about Oberlin. During 
the summer it must be sought in the deeper high woods. 
Its creeping habits and weak song make it an inconspicuous 
bird at best, and in the deep shadows of the woods it may be 
easily overlooked. 
This warbler is among the first of the great host of warb- 
lers which pass across the state—a few of them remaining all 
summer—late in April and early in May. It appears on our 
southern border about April 25th, and our northern border 
about three days later. In Lorain county it is common up 
to the middle of May and then the few which remain to 
breed retire to the deeper woods. The last have left the 
county by the 25th of September.

The distribution of this handsome warbler is largely de- 
termined by the special conditions favorable to its breeding.
