feeding upon the ground, when the white wing-spot is con- 
spicuous against the blue-black wing. 
It reaches southern Ohio as early as the 15th of April in 
favorable years, but seldom appears at Oberlin before the 
first of May. It remains about two weeks, and returns 
again early in September or even late in August, to remain 
until about the first of October.

This is an irregular warbler, sometimes being abundant 
and again hardly even common. It is the carliest to appear 
in spring and the latest to depart southward in autumn. It 
does not breed in the state as far as known. In its north- 
ward movement it is well distributed in the woods and 
parks, but in its southward journey it prefers to travel in 
the more open country, often with the Chipping Sparrow. 
At such times it may be seen in the fields gleaning among 
the weeds like a sparrow, or searching for insects in weed 
stems. It derives its name from its fondness for the berries 
of the myrtle (Myrica cerifera). 
During the spring passage of this species the insect food 
is greatly in the preponderance, although even then myrtle 
berries are eaten when they can be found, but during the 
autumn passage southward, when the fruit of the myrtle is 
abundant, it has been determined that fully 62 per cent. of the 
food is the myrtle berries. It seems remarkable that a bird 
supposed to be an insect eater should feed so largely upon 
this particular fruit. The myrtle berries are good for noth- 
ing, while the insects eaten are injurious. It is clear that 
this warbler deserves protection equally with the other warb- 
lers. 
The Myrtle Warbler appears in Lorain county about the
