THE ILLINOIS AUDUBON SOCIETY 
The Society was organized seventy-eight years ago for the protection of 
wild birdlife. Throughout its existence, the Society has promoted mea- 
sures to protect birds and to prevent destruction of the natural areas 
which birds need for survival. In many cases, IAS has worked to see that 
existing laws are observed, since mere enactment of laws never has 
guaranteed their enforcement. Illinois residents are invited to join the 
Society in advancing the cause of wildlife conservation, as well as in 
cooperative efforts with all other organizations which work for protection 
of our natural resources.
