Vegetable food. — Over 50 per cent of the robin's food consists of 

 fruit and more than four-fifths of this are wild species, even if straw- 

 berries, raspberries, and blackberries are classified as cultivated, 

 which is not always the case. Many complaints have been made 

 against this bird on the score of fruit eating and in many cases they 

 are well founded. In the vicinity of towns where cultivation and 

 improvements have swept away the wild fruits, or when for any 

 reason the crops of wild fruit fail, the birds are forced to resort to 

 cultivated varieties, and disaster to the farmer results. 



While such cases are not numerous or of very great importance 

 in the East, it is quite otherwise in California, where the robin is a 

 winter bird and is abundant at just the time when wild fruits are 

 largely out of bearing, except such as retain their fruit over winter. 



In years when this customary food is scarce, robins appear in the 

 valleys in immense numbers and eat olives so eagerly and persist-
