Christmas Bird Count at Big Oaks National Wildlife Refuge, Madison, IN

Join the annual effort to census the diversity of birds that spend their winter in the habitats of Big Oaks NWR. We will begin at 8am at the refuge office. Participants can either bird for a half or full day. Big Oak’s Conservation Society will be providing lunch for CBC participants. This is the first year that the National Audubon Society has made the CBC a free event for participants.  If you have questions or would like to confirm your participation, email refuge biologist Ben Walker at


Great Backyard Bird Count

This annual birdwatching and reporting event provides citizen scientists with the opportunity to document the birds seen on their area either in their backyard or a local park. The event is hosted by Audubon, the Cornell Lab of Ornithology, and Canadian partner Bird Studies Canada. The results provide a snapshot of the whereabouts of more than 600 bird species.

Anyone can participate in this free event and no registration is needed. Watch and count birds for at least 15 minutes on any day of the count. Enter your results at, where you can watch as the tallies grow across the continent. The four-day count typically records more than 10 million observations.

Spring Birdathon

The Birdathon is Knob and Valley Audubon’s only annual fundraising event.  The proceeds go to local and state environmental education and conservation activities. Get involved in this year’s Birdathon as a birder, a fundraiser, or both.
The Birdathon is a dawn to dusk marathon to sight as many different species as possible.  Birders cover a variety of habitats including Falls of the Ohio State Park, Charlestown State Park, Big Oaks National Wildlife Refuge and Muscatatuck National Wildlife Refuge.  You can form your own birding team or join one of our established teams. Lend your eyes and ears to the effort and help us reach our goal of 100 species for the 24-hour period.
Fundraising for the Birdathon is where the wings meet the wind.  You can help by making your own pledge, or get pledges from your friends and co-workers.  It’s not hard to do, and even small pledges of five or ten cents per species will make a big impact.
