A springtime has not yet passed without the arrival 

 of the migrating birds. Upon this attractive subject an 

 increasing number of new books appear every year, yet it 

 seems probable from the way in which successive printings 

 of this little book have been exhausted that there still ex- 

 ists a need for a simple, compact field manual at a minimum 

 price. 



The present edition is considerably enlarged by descrip- 

 tions of over fifty additional birds, a revised key and a 

 new table of comparative distribution. The entire subject 

 matter also has undergone a thorough revision with the end 

 in view of making the book useful in all localities in north- 

 eastern United States from the Mississippi to the Atlantic 

 coast. 



The authors wish to thank all those who have joined 

 hands with them in the past and hope in the name of the 

 birds that the circle may grow still larger in the days to 

 come.
