KAVAS hosts a variety of annual events for beginners and experts alike. Be sure to check below for more information on annual events.

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.

KAVAS Annual Meeting

Join us for this annual fundraising event as we search the forest, fields and streams to see as many bird species as possible and raise funds for our local environmental education and conservation projects.

Fall Big Sit

Knob and Valley Audubon organizes a Big Sit count at Falls of the Ohio State Park for our memebrs to enjoy this national event on the second weekend of October. From our 15ft diameter count circle, participants enjoy great views of the diverse habitats including the Ohio River, fossil beds and waterfalls, Shippingport Island, wooded riparian habitat and the bird feeders in the Interpretive Center. Participants enjoy bagels, donuts and coffee as they spend the morning and often times the afternoon listing the bird species observed from our overlook. Many thanks to Falls of the Ohio State Park for hosting our Big Sit circle. Join us for the next Big Sit!

Clean Sweeps

For several years, Knob and Valley Audubon has supported local efforts to keep our streams clean of litter by sponsoring a Clean Sweep at Lapping Park in Clarksville. Thanks to the success of this effort and the high level of participation over the years, this project has become adopted as part of the annual Ohio River Sweep sponsored by ORSANCO. The River Sweep is held at several locations in Clark County and along the New Albany Riverfront in June of each year. Join this annual effort along the length of the Ohio River (and Silver Creek) to help rid the riverbank of trash that washes down from upstream. Bring your family or group to make a significant difference in the community. For more information about the event, email Floyd County sweep coordinator Travis Elble at or Clark County sweep coordinator Carol Huff, at
