CHAPTER IV. 



VEGETABLE FOOD OF THE CROW. 



As already shown, the vegetable food of the Crow amounts to about 57 

 per cent of the whole food. Of this, corn is of the greatest importance 

 to the farmer, since its destruction is one of the most serious charges 

 made against this bird. But in addition to corn the Crow feeds on sev- 

 eral other kinds of grain and also on mast and many fruits and seeds. 



The following table shows the various vegetable substances found in 

 Crows' stomachs and the percentage of each to the whole vegetable 

 food for each month :
