abundant during the entire summer throughout the state: 
The food consists of 62 per cent. vegetable to 38 animal 
matter. Only 4 per cent. of the food is grain, and there 
seems to be no evidence that any fruit is eaten. Of the 38 
per cent. of animal food a large part consists of the cater- 
pillars of some of our most injurious insects. In large 
part these are such insects as other birds do not find be- 
cause they are afraid to come so near human habitations. 
Although not larger than your thumb, this little bird is 
among the most useful of our sparrows. 
It may be a resident in the southern counties, unless the 
weather is too severe. In northern Ohio it appears close to 
the first of April, but does not become common before the 
last of the month. The last ones leave the lake shore about 
the middle of October.

The Field Sparrow is really a bush-haunting sparrow, 
and is not infrequently called the brush sparrow. The 
brush fringing woods is the favorite haunt of this species. 
Brushy pastures are usually full of them and their nests. 
Their peculiar accelerando song is characteristic of such 
places. 
The food habits and food are very similar to those of 
Chipping Sparrow. Both deserve strict protection. 
The Field Sparrow spends the entire winter south of 
Ohio, and returns during the third week in March, rarely 
earlier. It remains well into October, and may linger until 
November in the extreme southern part of the state.
