BIRDS IN THEIR RELATIONS TO MAN. 



of spring-beetles and snout-beetles are but two per cent., the 

 numbers eaten are of some significance. My notes show that 

 these birds were eating each at the daily rate of one and one- 

 half curculios, and consequently had averaged a total of about 

 two hundred and fifty to each thrush for the season. The 

 brown thrush takes ants more freely than the robin, but eats 

 comparatively few caterpillars ; seven per cent, of each were 

 found in the food of the year. Diptera are taken in very 

 trivial quantity and Hemiptera in moderate numbers only.

This bird eats thousand-legs mere freely than the robin, espe- 

 cially in early spring. In the garden it plays a part very 

 similar to that of the other thrushes, but is less mischievous, 

 on the whole. Its average of the edible fruits for June, 

 July, and August is thirty-eight per cent., as against sixty per 

 cent, of the robin and forty-nine per cent, of the cat-bird. 

 It relishes the whole list of garden fruits, and later in the 

 season resorts to the wild fruits of the woods and thickets."
