THE TRAVELS OF BIRDS 



miles from Minnesota to Alaska is made in half 

 that time. 



Like flowers and trees, birds are closely de- 

 pendent on the weather. How little change there 

 is for weeks after the first skunk cabbage is seen, 

 or the first pussy-willow blooms! Then, as the 

 days grow warmer, the woods are suddenly filled 

 with flowers and the trees thickly covered with 

 leaves; and with these come the birds. 



From this glance at the birds' time-table, we 

 have learned that nearly every month in the year 

 has its bird travelers. This is one of the reasons 

 why the study of birds is so interesting. There 

 is always something happening in the birds' 

 world. Someone is coming or someone is going. 

 We are continually greeting old friends or mak- 

 ing new ones. 



Will it not add greatly to our pleasure to 

 know where they have been and whither they are 

 bound?
