 distribution of North American birds arc housed.

 in the Bird and Mammal Laboratories housed in

 by Division employees, arc available t<> investiga- 

 tors both in and out of the Bureau. The assistance 

 of thousands of banders, observers, and collectors 

 who have cooperated in obtaining these specimens, 

 or in providing data on them, makes this compre- 

 hensive service possible.
