Migration 



The study of bird migration is one of the most fascinating 

 branches of bird study. The air of mystery that pervades the 

 travels of birds over thousands of miles of land and sea, and the 

 cheery songs that announce their arrival in the spring have fur- 

 nished the inspiration that has led thousands of men, women 

 and children to the study of nature. Many of the phenomena 

 connected with the migration of birds, such as the height and 

 speed of their flight, the origin of their migrating instinct and 

 how they find their way, can not be illustrated with pictures 

 but many of the facts can, and the inspiration that comes to 

 people with the first arrival of birds in the spring should be used 

 to inspire them to pursue the subject of migration further than 

 the mere naming of the different birds as they arrive. Emphasis 

 should be laid upon the definiteness and the regularity of their 

 movements. A chart should be kept preserving arrival dates of 

 the different species each year.
