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