FOOD HABITS OF THRUSHES. 



regularity (3.86 per cent) throughout the season, but not in large 

 quantities. Diptera (flies) are eaten in small quantities and rather 

 irregularly. Most of them were the long-legged crane flies (Tipuli- 

 dee), both in the adult and larval form. The total for the season is 

 2.70 per cent. Hemiptera (bugs) do not appear to be a favorite 

 food, though a few were taken in all of the seven months except 

 October. The average for the season is only 1.33 per cent. Orthop- 

 tera (grasshoppers) are eaten in small quantities until July, after 

 which they form a fair percentage till September. The total con- 

 sumption amounts to 2.28 per cent of the food. A few other in- 

 sects make up a fraction of 1 per cent. Spiders and myriapods 

 (thousand-legs) appear to be a favorite food with the wood thrush, 

 constituting in April 20.94 per cent of the. food, but gradually de- 

 creasing in quantity until September. The aggregate for the year- 

 is 8.49 per cent. A few sowbugs (isopocls), snails, and earthworms 

 (1.83 per cent) close the account of animal food.

Vegetable food. — More than nine-tenths of the vegetable food of 

 the wood thrush can be included in a single item — fruit. Culti-

 taken from June to September, inclusive. It was eaten regularly
