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 
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 
organizations which work for the protection of our natural resources. 
Headquarters of the Society are at the Chicago Natural History 
Museum, Roosevelt Road and Lake Shore Drive, Chicago 5, where literature 
and information may be obtained, and where public lectures are held.
