356 NATURE STUDY AND LIFE

 one out of the nest ? 



It is a fascinating study to discover how the parent 

 birds tide their nestlings over this most difficult period of 

 their lives. Ask the pupils to watch a family of birds as 

 the young leave the nest and to describe what they see. 

 Olive Thorne Miller writes of seeing one parent bird 

 call her young one into a berry bush, and while the 

 youngster clamored for food and held its mouth wide 

 open, she quietly helped herself, as much as to say :

 class offered to help. They, every one, simply held their 

 mouths open and begged. He tossed the squirming bits 

 on the ground before them. Not one caught the idea,
