Bird Banding in Northern Michigan 89 



spent the winter either in northern United States or in 

 Canada. With the banding of more birds the likelihood 

 will be greater of finding out just where in the north these 

 or other birds nest. 



3. Do nesting birds use the same nest and have the 

 same mates season after season ? 



4. Do birds wander far from their nests in search 

 of food? 



5. Do certain birds rear a second brood in the same 

 nest or in the same region as the first brood? 



6. Do young birds return to breed to the spot in which 

 they were reared? 



No. 251, a half-fiedged Robin, was banded at Kingston, 

 Rhode Island,' August 4, 1908, and was recovered April 9, 

 1909, at the same place not more than 200 jards from the 

 orchard in which it was reared. 



7. Do migrating birds stop off" at the same feeding 

 places eti route year after year? 



8. Do certain individual birds come and go over the 

 same migration route? 



Records of the movements of individual birds will give 

 valuable information concerning some of the general prob- 

 lems of migration. However, some means must be avaO- 

 able for positively identifying these 'ndividuals, a means 

 to be attained only by banding or otherwise marking in 

 some permanent manner. 



9. What is the rate of travel (not flight) of certain 

 species of birds? 



10. What is the rate of geographical extension of a 

 given species? 



11. How long do birds live? 



A young Common Tern was banded at St. Clair Flats 

 Canal, Michigan, August 13, 1909 (No. 4590). The bird 

 was recovered at Whitebread, Ontario, Canada, August 5,
