The bison herd at Midewin National Tallgrass Prairie in Wilmington just got a little bit bigger and a whole lot cuter after officials announced the birth of the first calves of the season.
So far, they've confirmed there are two new calves roaming the prairie.
The births couldn't have come at a better time considering the bison tours are set to kick off on May 6.
The tours will be held every Saturday and Sunday starting at 11 a.m., where volunteer rangers will lead guided hikes in search of these impressive national mammals.

The bison have been a big draw at Midewin since the herd’s arrival in October 2015, but can be elusive for visitors to find considering they roam a 1,200 acre area. In 2016, a Bison Cam was installed to help provide a real-time view.
While the Iron Bridge Trailhead is closest to the herd's grazing area, visitors also can access Midewin via the Forest Preserve District's Wauponsee Glacial Trail. The Midewin-Wauponsee Trailhead, which opened in 2015 and was created through a partnership between the Forest Preserve District of Will County and the U.S. Forest Service, is located at the intersection of Hoff Road and the Forest Preserve District's Wauponsee Glacial Trail.
