Birdsong Big Sit Team Places 3rd!

In late September, a state birding event, The Big Sit, was hosted by the Illinois Audubon Society. The event is very similar to a Global Big Day; a competition in which bird watchers counts as many species as possible in a 24-hour period. While Global Big Day involves moving from place to place to maximize the number of species spotted, The Big Sit competition is exactly as it sounds and stays in one place.

A circle 17’ in diameter, called a "count circle”, is set up and only species observed or heard from that circle count for the final species total. A Birdsong Chapter team took third place out of 41 teams across Illinois in the number of birds observed and first place in hours of observation with a total of 71 species and 15 continuous hours of birding.

Our team, “Just Winging It” was made up of five observers, including Dave Brewer, James Hampson, Stephen Hager, and Adrianh Martinez-Orozco. We assembled a team of ringers! Jim has birded forever and has participated in over 50 Christmas Bird Counts, Steve is a Biology/Ornithology professor at Augustana, and Adrianh is a photographer,  veterinarian and occasional bird tour leader. Our count circle was located at Gremel Wildlife Sanctuary near Amboy at the edge of the woods and by the edge of a pond and a small wetland. If the birds are in our favor, next year, we’re taking first!

Education & Outreach

The 352 acres of Amboy Marsh and 430 acres of Gremel are critical habitat that was once part of the wetlands in Lee County called the Inlet and Winnebago Swamps. These peaceful sites are home for many flora and fauna.  With the goal of restoring and protecting habitat, the areas do not offer amenities for people, but you may enjoy great hikes, photography and birdwatching.  An additional 20 acre Ryback site and 80 acre Grigalouski site provide additional habitat in Lee County.  

 

If you feel a connection to the marsh, join the group that cares for this place: The Birdsong Chapter of Illinois Audubon Society. Learn more about what we do and how you can join. Contact amboymarsh@illinoisaudubon.org

Our main goal is to preserve habitat for plants and animals at the sites.  We hold work days, offer programs at monthly meetings of the Birdsong Chapter and host other outdoor events.  Contact us to learn more about our organization on Facebook at Birdsong Chapter-Stewards of Amboy Marsh/Gremel, or at https://illinoisaudubon.org/location/amboy-marsh-nature-preserve/.  Our email is
amboymarsh@illinoisaudubon.org.

 Please contact us to schedule any day you would like to come out to work.  There is plenty to do and we'll work with you to find something that suits your interest and schedule. amboymarsh@illinoisaudubon.org
