Conserving Our World

The good stewardship of planet Earth.
This cause compels and motivates us at the Northwest Illinois Audubon Society (NIAS). Of course we love birds, but since our founding in 1971 we have embraced a bigger picture, emphasizing the interrelatedness of resource protection, habitat conservation, and connecting people with nature.

With a membership of more than 300 families, our chapter owns, manages, and works to protect two local biodiversity preserves — each with more than 40 acres and hundreds of identified species of plants, animals, and birds.

Conserve Butterfly on Purple Coneflowers Wildlife Wednesdays

We publish a bimonthly newsletter announcing regular activities and events, such as educational programs, bird walks, and field trips — all open to the public.

We also sponsor annual special events such as:

  • Butterfly and bird festivals
  • Christmas Bird Count
  • Bird-A-Thon
  • Birdseed sales
  • Annual banquet

Help us conserve our world and enhance our own special piece of the planet, right here in northwestern Illinois. Join us.
