THE FOOD AND FEEDING OF FLEDGLINGS. 
BY NEWTON MILLER. 
(Abstract). 
Several species of young birds were observed 
throughout a complete bird’s day. The data thus col- 
lected show rhythms of feeding and give a good idea of a 
day’s work of the various birds. The data also gave an 
index to the amount and kind of food consumed. The 
amount and kind of food used is one of the determining 
factors in computing the economic importance of a 
species. 
Young birds do not get all the food they desire. 
There is a struggle for the offerings of the parents and 
usually one gets more than his share. This in part 
accounts for the frequent occurrence of one large or one 
small fledgling in each nest. The young cowbird is the 
notorious example. 
The complete article will be illustrated with charts.
