THE ILLINOIS AUDUBON SOCIETY 
The Society was organized over sixty years ago for the protection ) 
of wild birdlife. Throughout its existence the Society has promoted - 
measures to protect birds and to prevent destruction of the natural areas — 
that birds need for their survival. In many cases the Society has worked — 4 
to see that existing laws are observed, since mere enactment of laws 
has not guaranteed their enforcement. We invite you to join us in advanc- 
ing the cause of wildlife conservation and in cooperating with all other i 
organizations which work for the protection of our natural resources. — ie 
Headquarters of the Society are at the Field Museum of Natural _ 
History, Roosevelt Road and Lake Shore Drive, Chicago 5, where literature — 
and information may be obtained, and where public lectures are held. —
