This past weekend, I went on a field trip with South Bend-Elkhart Audubon Society to Kankakee Sands (and briefly Willow Slough Fish and Wildlife Area) in Newton County, Indiana. Kankakee Sands is a nearly 8000-acre restoration area where prairie (ranging from dry to wet) is the target plant community. Many of the grasslands where we were birding are still quite weedy botanically, but the birds didn't know the difference.
Dickcissel (Spiza americana), shown below, and Grasshopper Sparrow (Ammodramus savannarum) seemed to be the most common birds, singing incessantly while we were birding.
Our bird list for the morning:
Northern Bobwhite (heard only)
Great Blue Heron (while driving)
Turkey Vulture (while driving)
Sandhill Crane (while driving)
Ring-billed Gull (while driving)
Bell's Vireo (heard only)
