From WTTW’s Chicago Tonight, April 27, 2016: The bison herd at Fermi National Accelerator Laboratory just got a little bigger. On Tuesday, the first bison calf of 2016 was born at the particle physics laboratory located in suburban Batavia, roughly 35 miles from Chicago.

Fermilab is looking for volunteers to help with its annual prairie seed harvest. Two harvest events are planned, on Saturday, Oct. 5 and Saturday, Nov. 2, beginning at 10 a.m. Fermilab’s site hosts 1,000 acres of restored native prairie land, and each year community members pitch in to help collect seeds from those native plants.

Enjoy a day of bison, birds and bugs while learning about science and fun things to do outside at Fermilab’s Family Outdoor Fair on Sunday afternoon, June 10, 2012.
