bers, since the places where the bird now nests are numer- 
ous enough for its purposes. True, it does not go out of the 
taller woods to breed, but it seems to find woods enough 
suitable for breeding places. It may be, however, that dur- 
ing the earlier days it was confined to the deeper woods and 
the rapid disappearance of them has driven many to other 
regions. In Lorain county it is to be found in every con- 
siderable woods, but is only common here. 
The Cerulean Warbler arrives with the warbler host, 
about the first of May in northern Ohio, and is fairly com- 
mon for two weeks. The departure northward of a major- 
ity of the individuals leaves the state thinly settled with 
Ceruleans. It passes south during the last week of Septem- 
ber.

Of all the warbler host this is to me the most interesting, 
in its parti-colored dress and confiding ways. The day that 
brings them is the brightest day of the season. In their 
northward movement they are not particular about the places 
where they feed, provided the insects are numerous and the 
trees are not too far apart. Every year we see numbers of 
them on the College Campus. I have seen them in the door- 
yard, in the apple-trees, and in the deep woods among the 
highest branches. It is common only locally, apparently. 
Dr. Wheaton gives it as a summer resident in the north-east- 
ern parts of the state. It is not unlikely that it still breeds 
in the northern part of the state, but if so it has not been so 
reported to me. None have been found in summer in Lorain 
county. 
This is one of the warbler host which reaches Oberlin 
about the first of May, remaining about two weeks and then
