THE ILLINOIS AUDUBON SOCIETY 
The Society was organized seventy years ago for the protection of wi 
birdlife. Throughout its existence, the Society has promoted measur 
to protect birds and to prevent destruction of the natural areas whi 
birds need for survival. In many cases, the Society has worked to s 
that existing laws are observed — since mere enactment of laws nev 
has guaranteed their enforcement. Illinois residents of all walks of li 
are invited to join the IAS in advancing the cause of wildlife conservatio 
as well as in the Society's cooperative efforts with all other organizatior 
which work for protection of our natural resources. 
Headquarters of the Illinois Audubon Society are in the Field Museu 
of Natural History, Roosevelt Road & Lake Shore Drive, Chicago 6060, 
where public lectures are held. Individual and group membership su;
