Introduction 



Migratory birds make up a resource that is shared by many people of many 

 nations. Public awareness of marine birds their manifold values, eco- 

 logical requirements, and problems is prerequisite to their protection. I 

 am proud that the Fish and Wildlife Service can further this needed aware- 

 ness by publishing these proceedings of the international symposium 

 "Conservation of Marine Birds of Northern North America."
